parvo fere bipartito, lobis oblongis divergentibus ; seminibus inordinate tuberculatis. -— Upper Valley of the Sacramento, south of Mount Shasta, Brewer. Lake County, Torrey. Mount Bullion, Mariposa County, Bolander.

Var. OVALIFOLIUM: foliis ovalibus retusis, superioribus emarginatis, ramealibus parvis orbiculatis ; calyce breviore, segmentis oblongis. With Prof. Brewer's specimens from the Upper Sacramento. - Larger leaves about an inch long, including the petiole. Flower 5 or nearly 6 lines long; lower lip, with its very prominent palate and oval lobes, very much larger than the upper.

ANTIRRHINUM VAGANS: pilis patentissimis rigidulis interdum glandulosis hirsutum, nunc glabratum ; foliis lanceolatis oblongisve, ramealibus nunc linearibus nunc orbiculatis ; calycis segmentis valde inæqualibus, postico angusto- seu lato-oblongo obtusissimo 3 – 5-nervi corollæ tubo æquilongo, cæteris linearibus ; corollæ purpurea? sacco amplo, labio superiori bilobo palatum adæquante; seminibus inordinate tuberculatis. — Near San Francisco, valley of the Upper Sacramento, and other parts of California, collected by Fremont, Brewer, Bolander, Torrey, Heermann, &c. Also a very glandular-hirsute form by the late Mr. Bridges. Flowers from 6 to 8 lines long, sometimes much scattered, often rather crowded and racemose or spicate at the upper part of the branches.

Var. BOLANDERI: floribus in axillis valde remotis; foliis superioribus orbiculatis vel subcordatis ; calycis maxime inæqualis segmento postico late ovali. — In the Redwoods, Marin County, Bolander. This variable species, and especially the variety here indicated, well shows the cirrhose character of the slender branchlets, which frequently hook or coil with one or two turns around some slender object, the coil thickening and hardening as in analogous cases.

§ 2. MAURANDELLA. (Maurandiæ sp. personatæ.) Corolla palato prominente faucem vix ac ne vix claudente. Filamenta sursum vix ampliata. Capsula fere æqualis. Semina fere Antirrhinastri. – Herbæ pedunculis petiolisve flexuosis vel cirrhiformibus sæpius scandentes, foliis plerisque alternis.

* Herbæ annuæ, pedunculis elongatis tantum scandentes vel erectæ, basi pilosæ, cæterum glabræ ; foliis integris, petiolis brevibus rectis vel subnullis.

A. STRICTUM (Maurandia stricta, Hook. & Arn., Benth.): caule erecto 1 - 2-pedali ; foliis lanceolatis, floralibus linearibus; pedunculis filiformibus flexuosis dissite racemosis ; corolla violacea semipollicari, palato piloso; capsula ovoideo-globosa crustacea stylo longo rigido superata calycis segmentis lato-lanceolatis paullo longiore ; seminibus rugoso-muricatis. — Near Santa Barbara, Douglas; a very slender and strict, small-leaved form. Very dry hillside, Santa Inez Mountains, Santa Barbara, March, 1861, Brewer; more robust and leafy : leaves 11 to 24 inches long, many of the lower fully half an inch wide, contracted at base into a distinct petiole of half an inch in length : branches developing in many of the axils. The tortuous peduncles, about 2 inches long, evidently become prehensile upon occasion.

ANTIRRHINUM FILIPES, Gray (in Ives Colorado Exped. Bot. p. 19): tenellum, diffusum ; foliis lanceolatis imisve obovatis repandis in petiolum attenuatis; pedunculis capillaribus prælongis cirrhoso-tortilibus ; floribus parvis “albis ”; capsula globosa. — Desert arroyos of the Colorado, Dr. Newberry. Specimen imperfect. Allied to the next : but the flowers seem to be very small, and are said to be white.

ANTIRRHINUM COOPERI: gracile, ramosissimum, scandens ; foliis linearibus seu lineari-lanceolatis in petiolum breve attenuatis ; pedunculis capillaribus cirrhosis, superioribus secus ramos filiformes nudos racemosis ; corolla flava semipollicari, palato amplo piloso faucem subclaudente; capsula globoso ; seminibus ventre ruguloso-muriculatis dorso costis 3 – 4 crassis suberosis instructis. — Gravelly ravine near Fort Mohave, Feb. 27, 1861, Dr. J. G. Cooper. “Twining 3 – 4 feet high.” Peduncles 2 or 3 inches long, coiling freely.

§ 3. GAMBELIA. (Gambelia, Nutt. Pl. Gamb., in Jour. Acad. Philad. ser. 2. 1, p. 149.) Corolla tubulosa basi leviter gibbosa, palato prominulo faucem non claudente, labiis brevibus, postico erecto bifido, antico lobis 3 patentibus. Filamenta sursum vix ampliata. Capsula æqualis. — Frutices vel suffrutices Austro-Californici, erecti, foliis oppositis vel ternato-verticillatis passim subalternis integerrimis, summis diminutis. Pedunculi axillares, longiusculi.

ANTIRRHINUM SPECIOSUM= Gambelia speciosa, Nutt. I. c. Catalina Island, Dr. Gambell. Leaves oval or oblong, an inch or less in length, and with a short petiole, not unlike those of A. latifolium. Corolla almost an inch long, said to be “scarlet," apparently rather pink-red, the narrow tube thrice the length of the lips.

ANTIRRHINUM JUNCEUM = Mauraudia juncea, Benth. Bot. Voy. Sulph. p. 41. From San Diego to the Bay of Magdalena, Hinds. I have not seen this; but it seems to be a congener of the last, but with smaller flowers and leaves, the uppermost reduced to minute scales. The seeds as described are those of Antirrhinastrum.

MAURANDIA, Ort. This genus, relieved of the section Antirrhinifloræ Benth., and connected through the wing-seeded M. Wislizeni with Lophospermum, now secures more definite characters.

M. viscida, Gray in Bot. Whippl. (Pacif. R. R. Exped. 4) p. 66, in Ives, Colorado Exped. Bot. p. 19. — In addition to the imperfect specimens gathered by Coulter, Bigelow, Newberry, &c., we now have it with both fine flowers and mature fruit, collected by Dr. J. G. Cooper, February 18, 1861, in a gravelly ravine at Fort Mohave. The specimens mostly do not exceed a span in height; but it is noted that the plant attains the height of two feet. The flower is fully an inch and a half in length. As already stated, I suspect Antirrhinum conferti florum, Benth., may be founded upon an imperfect specimen of this remarkable plant; yet the flowers are not subsessile, nor the calyx-segments shorter than the tube of the corolla. .

TONELLA COLLINSIOIDES, Nutt., taken up by Benth. in DC. Prodr. 10, p. 593, as Collinsia tenella, — having solitary ovules, corolla scarcely gibbous at the base and with an open limb, with the sinuses between the two lateral and the lower (explanate) segment rather deeper than on the posterior side, — may fairly claim the generic ranki Bolander collected it in Mendocino County.

COLLINSIA TORREYI: caule tenello ramosissimo superne cum pedicellis calyceque glandulosis ; foliis glabris linearibus subdenticulatis basi attenuatis, floralibus superioribus minimis vel obsoletis; pedicellis quasi verticillato-racemosis calyce duplo longioribus ; calycis segmentis lanceolato-oblongis obtusis corollæ labiis inæquilongis plus dimidio brevioribus. — Mariposa, Big-tree Grove, and near Donner Lake, Dr. Torrey. At Clark's Ranch, Bolander. A span high, the cauline leaves 14 inches long. Verticillastri 4-6-flowered, mostly in a naked raceme. Corolla blue, about as large as in C. parvi flora, but the calyx very much shorter, only about one third the length of the lower lip, which moderately exceeds the upper. I name it for the earlier discoverer, that it may be one of the permanent memorials of our oldest active botanist's visit to California, and to the “ Mammoth Grove,” in the shade of which this delicate little plant grows.

COLLINSIA CORYMBOSA, Hortul. (I know not the origin of the name, which is less appropriate than capitata would be), a depressed species, with rounded leaves, almost capitate inflorescence, broad calyx-lobes, and extremely short upper lip of corolla, was collected by Bolander on the coast at Fort Bragg, Humboldt Co.

COLLINSIA SOLITARIA, Kellogg, in Proceed. Acad. Calif. 2, p. 10. Depauperate specimens collected by Prof. Brewer, in April, in Marin Co., remarkable for their ovate calyx-lobes, equalling the broad tube of

the corolla, evidently are of this species. Dr. Brewer notes that the tube of the calyx is rose-colored, while the lobes are green. According to Dr. Kellogg, not only the calyx-tube, but also the peduncles, are bright purple. According to Dr. Brewer, the corolla is dotted with brown spots, the upper lip light yellowish.

PentSTEMON Palmeri (inter P. Jamesii et Cobæam): sesquipedalis; foliis lanceolato-ligulatis argute denticulatis cauleque glaucescentibus, superioribus semiamplexicaulibus, inferioribus spathulatis in petiolum attenuatis; panicula nuda racemiformi virgata laxiflora glanduloso-puberula ; bracteis minimis; pedunculis 2 – 3-floris ; pedicellis gracilibus ; sepalis ovatis glabriusculis ; corolla pollicari pallide purpurea supra calycem latissime campanulato-ampliata, ore hiante, labio inferiore intus hirsuto; filamento sterili leviter exserto apice incurvo insigniter flavo-barbato: — Arizona, in Skull Valley, and on Rio Verde, near Fort Whipple, Drs. Elliott Coues and Edward Palmer. A well-marked species, with sterile filament bearded in the manner of P. cristatus, and corolla even more dilated in proportion than that of P. Cobæa.

PENTSTEMON BRIDGESII (Saccanthera): præter inflorescentiam glaber; caule erecto 1 - 2-pedali ; foliis integerrimis spathulato-lanceolatis linearibusque, caulinis sessilibus; panicula virgata racemosa, pedunculis 2 - 5-floris; sepalis ovato-oblongis acuminatis cum pedicellis æquilongis viscoso-pubentibus; corolla coccinea (pollicari) cylindraceotubulosa sursum leviter ampliata, fauce nuda, labio superiore erecto apice bilobo, inferiore tripartito, lobis recurvis oblongis tubo 2 - 3-plo brevioribus; filamento sterili nudo apice complanato; antheris quasi sagittatis apice solum dehiscentibus (rima hirtello-denticulata), loculis deorsum maxime productis diu parallelis. — No. 218 in Californian collection of the late Thomas Bridges. Yosemite Valley, very scarce, Bolander. A handsome and very interesting new species, having the anthers most distinctly of the section Saccanthera, but the habit and corolla of the section Elmigera. In cultivation it would rival P. barbatus and its allies.*

* To the Cheloneæ there is apparently to be added a new genus, namely,

BERENDTIA, nov. gen. Chelonearum post Leucocarpum. Calyx tubuloso-campanulatus, subangulatus, fere æqualiter 5-dentatus. Corolla infundibuliformis, bilabiata, labiis patentibus subæqualibus, superiore bilobo, inferiore trilobo, lobis brevibus rotundatis. Stamina 4, didynama, absque rudimento
