– Shasta Co. California, A. Wood, 1866. On the divide between Russian and Eel Rivers and northward, Bolander, 1867. Professor Wood has naturally characterized this very striking and handsome plant as a new genus, — to which, indeed, it has as good a claim as Dichelostemma or perhaps even Stropholirion. But, however Brodiæa be limited, it cannot well fail to include this species, which has wholly the structure of the typical B. grandiflora, only that the tube of the flower is proportionally longer, the scales answering to the other set of stamens much broader, and the color peculiar in the genus, although not unlike that of Stropholirion. In referring it to Brodiæa we may venture to discard the objectionable double-headed specific name, given by the stage-driver, Mr. Burke (who showed the plant to Professor Wood), “ in affection for his little daughter.

ALLIUM OCCIDENTALE = A. reticulatum, Ilook. Fl. Bor.-Am. pro parte, & Pl. Hartw. No. 1995 ; ab A. reticutato Fras. differt bulbo nunquam vaginis reticulatis tecto, segmentis perigonii latioribus, cristis seu dentibus ovarii brevissimis, etc. Apparently common in California.

ALOE YUCCÆFOLIA (Yucca ? parviflora, Torr. Bot. Mex. Bound. p. 221): acaulis ; foliis elongatis angusto-linearibus recurvo-patentibus rigidis canaliculatis tenuiter striatis lævibus margine Yuccæ modo filiferis ; scapo 2 – 4-pedali scarioso-bracteato; racemo vel panicula elongata ; fioribus fasiculatis; perianthio æquali cylindrico dilute rubro ; filamentis rectis subexsertis ; stylo demum longius exserto; capsula ovata primum carnosa demum 6-valvi. – S. W. Texas, C. Wright (685, with flowers and mature fruit), 1908 (with unripe fruit, &c.), J. M. Bigelow, ex Torr. Flowers an inch long. Style at length with the exserted portion incurved or geniculate in the flowers developed in Cambridge Botanic Garden. Fruit and seeds, no less than the leaves, resembling those of Yucca.

HESPEROCALLIS, Nov. Gen. Liliacearum. Perigonium corollinum, infundibuliforme, marcescendo-persistens ;. limbo regulari 6-partito tubo longiore, segmentis conformibus oblongospathulatis basi attenuatis medio 5 – 7-nervatis. Stamina 6, fauci inserta : filamenta filiformia, recta : antheræ lineares, supra basim introrsum affixæ. Ovarium triloculare, loculis multiovulatis: stylus filiformis: stigma depresso-capitatum. Capsula subglobosa, loculicida, polysperma. Semina compressa, exalata, testa ut videtur subcarnosa molli. — Herba

glaberrima ; caule foliato bipedali e “ bulbo eduli” (an cormo?); foliis linearibus elongatis crassis planis margine insigniter undulatis ; racemo paucifloro ; pedicellis brevibus bractea scariosa suffultis cum flore articulatis.

HESPEROCALLIS UNDULATA. — Desert plains at Jessup Rapids, Arizona or New Mexico ; " the bulb eaten by Indians,” Prof. Newberry. Gravelly plains at Fort Mohave, Dr. J. G. Cooper. Flower 2 inches long. Capsule half an inch or more in length, apparently thickish. The seeds seen not fully ripe, but evidently with a soft or rather fleshy-coriaceous testa. The plant appears to be most related to Hemerocallis, and the generic name is intended to suggest that affinity, along with the far western, instead of eastern habitat. The “ bulb,” whatever it may prove to be, did not accompany the specimens of either collector.

NARTHECIUM OSSIFRAGRUM, Linn., var. OCCIDENTALE. Swamps at Red Mountains, Humboldt Co., Bolander. An interesting discovery in a geographical aspect, this, with the recent detection of a new species (N. Asiaticum, Maxim.) in Japan, greatly extending the range of the genus. While the Japanese species, by its narrow sepals, shortish anthers, and shorter more crisped wool of the filaments, most approaches N. Americanum, the present plant, with loose raceme and broadish leaves, closely resembles the W. European plant; from which it seems to differ only in the rather broader, and perhaps larger, divisions of the perianth. The position of the bractlet varies, as it also does in the other forms.

VERATRUM FIMBRIATUM: foribus fere pollicem diametro insigne, perianthii phyllis obovato-cuneatis supra unguem. brevem latum composite longeque fimbriatis ; foliis V. viridi similibus, majoribus sesquipedalibus. — On the undulating plains west of the Redwoods in Mendocino County, Sept., 1865, Bolander. The flowers of this most remarkable species are apparently greenish-white, with two darker spots at the base of the lamina.

HEMICARPHA OCCIDENTALIS: pallida ; capitulis solitariis binisve ovatis vel subglobosis hystricinis ; squamis e basi ovata scariosa costa valida percursa in acumen patulum rigidum æquilongum productis achenium cum squamula interna ovata eroso-truncata vel excisa ter longioribus. — Common in Yosemite Valley, Bolander. This apparently grows, just as does H. subsquarrosa in the Eastern United States, in company with Cyperus inflexus. Heads much thicker than those .


of the original species, owing to the long and squarrose points of the scales, pale greenish.

ELEOCHARIS BOLANDERI: E. uniglumi similis, absque rhizomatibus repentibus modo E. multicaulis ; caule tenuiori striato-angulato; stigmatibus 3 ; achenio albido lævi pyriformi angulis 3 acutis costato, apice quasi truncato tuberculo latissimo depresso fere disciformi prorsus confluente coronato; setis tenuibus 3 – 4 retrorsum scabris achenio 2 – 4-plo brevioribus. — Mariposa County, on banks of stream near Clark's, Bolander. Fruit mostly immature in the specimens : scales of the spike dark brown.

SCIRPUS (ISOLEPIS) PYGMÆUS, — preserving the earliest specific name for this common Californian as well as S. American and Australian plant, which was inadvertently named “ Isolepis carinata” in an early distribution of some of Mr. Bolander's plants, No. 57. It is Isolepis leptocaulis, Torr. in Bot. Whippl. p. (153) 97. It appears to grow in company with, but is quite distinct from,

SCIRPUS (ISOLEPIS) CARINATUS, the Isolepis carinata, Hook. & Arn., which is near I. cartilaginea, R. Br.

Scirpus (TRICHOPHORUM) CRINIGER : caulibus e rhizomatibus dense cæspitosis strictis (bipedalibus) triquetris, angulis sub apice scabris; foliis planis, radicalibus angusto-linearibus elongatis, caulinis lato-linearibus brevibus sæpius vagina brevioribus; spicis paucis oblongis in capitulum unicum rariusve geminatum arcte congestis ; involucro monophyllo subulato vel subnullo ; squamis ovatis tenuibus trinervibus fulvis muticis (infima majore bracteante' acuminata vel cuspidata) filamentis 3 et perigynii setis 6 tenuibus antrorsum scabris dimidio brevioribus ; achenio obovato-triquetro cuspide brevi apiculato. - In bogs, on Red Mountain, Humboldt Co., Bolander. An interesting plant, with nearly the habit and inflorescence of Eriophorum Virginicum, but usually with only one glomerule, composed of 5 to 9 very crowded spikes, and the involucre small and simple or none, and comose with fulvous, but not very tortuous, long bristles and persistent filaments. The number and the serrulation of these bristles refer the species to Trichophorum ; rather than to Eriophorum. The rather broad cauline leaves are from 3 to only 14 inches long, acute, smooth, or the edges minutely scabrous.

The Carices of these collections having been referred to Mr. Olney, he has obligingly furnished characters of the following proposed new species, along with two or three of Eastern habitat.

Carices Novæ a STEPHEN T. OLNEY, A. M., descriptæ, 1868. CAREX BOLANDERI, Olney, n, sp.: spica elliptica pallida albo-viridi demum lutescente e spiculis 5 – 6 (rarius 4-10) parvis ellipticis sessilibus plerumque androgynis basi masculis, superioribus contiguis, infima vel binis inferioribus remotis bracteatis ; stigmatibus 2; perigyniis ovalibus vel ellipticis acuminato-rostratis bifidis plano-convexis margine acutis serratis nervatis basi spongiosis squama ovata hispida aristata albo-hyalina nervo viridi longioribus; achenio orbiculato vel ovato punctulato straminco, basi styli plus minus bulbosa. — California, Yosemite Valley and Mariposa Big-tree Grove, Brewer, 1665; Dr. Wm. Hillebrand, 2313 ; Bolander, 6201, 6209. This is closely allied to C. Deweyana, Schweinitz, from which it differs in its less acutely angled culm, more approximate and many- (10 – 30-) flowered spikes, shorter bracts, the oval or elliptical and nerved perigynia, and longawned hispid scales.

CAREX ATHROSTACHYA, Olney, n. sp. : spica globosa capitata in- . volucrata straminea e spiculis 8 – 20 basi masculis dense congestis vel infima subinde discreta ; bracteis 3 – 5 inferioribus foliaceis spicam longe superantibus, basi expansa hyalino-marginata ; stigmatibus 2 ; perigyniis ovato-lanceolatis in rostrum elongatum attenuatis basi spongiosis marginibus alatis serratis alte bifidis leviter nervatis ; squama ovato-lanceolata acuminata membranacea ; achenio orbiculato planoconvexo lucido nec punctulato. — California, Yosemite Valley, June 17, Brewer, 1650; Hillebrand, 2311, a var.; Bolander, 6213; Silver Valley, alt. 7,400 feet, Brewer, a variety. — Cæspitose : culms acutely triangular, leafy, 13 - 2 feet high; leaves narrow, shorter than the culm. Allied to C. sycnocephala, Carey ; from which it differs in its shorter leaves, heads with more spikelets, bracts expanding at the base into a membranaceous border, and broader and more ovate irregularlynerved perigynia.

CAREX STRAMINEA, Schk., var. congesta, Boott, in litt. Apr. 1863: spica congesta, squamis castaneis. — California, Brewer, on Mount Shasta, 1375, 1397, 1398, 1399.

Carex Silicea, Olney : “spiculis 2 – 10 pallidis demum stramineis plerumque alternatim remotiusculis omnibus (terminali sæpe magis conspicue) basi conico-masculis nudis, infima subinde composita ; perigyniis ovalibus vel orbiculatis e basi late alatis brevi plerumque sensim rostratis compressis appressis plus minus plurinerviis squama lanceolata acuminata acuta latioribus paulo longioribus vel æquantibus.” VOL. VII.



C. straminea, var. moniliformis, Tuckerm. Enum. p. 17. C. straminea, var. Sartwell, Exsicc. No. 49. C. foenea, Boott, Ill. Car. 3, p. 118, tab. 377. C. fænea, var. ? sabulonum, Gray, Man. ed. 5. C. adusta, Carey in Gray, Man. ed. 1. non. Boott. C. festucacea, Sartwell, Exsicc. No. 44, ex parte. — Maine, on the coast, rocks and beaches, Tuckerman. New Hampshire, Isle of Shoals, Canby. Rhode Island, on rocks and beaches, Narragansett Bay. Massachusetts, Ipswich, in sand, Oakes. New York, Sartwell. Cape Henlopen, Delaware, Canby. June, July. — The different color, the alternate spikelets, nutant spikes (in this resembling C. straminea, var. aperta, Boott), and involute leaves, surely separate this from C. fænea. The fruit matures early ; that of C. fænea ripens a month or more later.

CAREX SENTA, Boott, n. sp. : “Mr. Brewer has recently found in California specimens which, in habit, closely resemble C. angustata, Boott, but differs in the perigynum being conspicuously toothed at the margin, and the vagina of the leaves externally scabrous, and in the larger size of the perigynum.” Boott, Ill. Car. 4, p. 174. It is Brewer's No. 350, which was collected in a cañon of the Santa Inez Mountains, California.

CAREX BIFIDA, Boott, n. sp. “ With the habit of C. Buxbaumii Wahl. differs in the bifid orifice of the perigynum, which is not granulated ; the leaves are broader, and scales shorter.” Boott, MSS. April, 1863. It is Brewer's No. 574, of Salinos Valley, south of Monterey, and Bolander's 6476 from Red Mountain, Humboldt County.

CAREX GYNODYNAMA, Olney, n. sp.: spicis 4-5 cylindricis erectis ferrugineis, terminali masculi apice fæminea, reliquis fæmineis, suprema masculam longe superante, infima remota longe vaginata pedunculata ; bracteis involutis ciliatis, infima culmo subæquali vel breviore; stigmatibus 3 ; perigyniis ellipticis rostratis bifidis olivaceis basi leviter nervatis (apice purpureo pilis longis albis vestito, basi glabra) squama ovata membranacea ciliata mucronata vel acuta castanea medio pallida latioribus et brevioribus; achenio obovato triquetro olivaceo. — California, near Mendocino City, Bolander, 4700. Cæspitose : culms 10 – 18 inches high, leafy, and with long sheaths : leaves much shorter than the culm, flat, ciliate. This species probably belongs to the Ferrugineæ group.

Carex WHITNEYI, Olney, n. sp.: spicis 4 (rarius 3 – 5) erectis albo-viridibus, terminali masculi (rarius 2) oblonga vel cylindrica rarius pedunculato, reliquis foemineis evaginatis sublaxifloris oblongis
