oribus minimis, mediis triplo majoribus 9-nerviis lævibus, interioribus brevioribus uninerviis. — On the mountains of Hawaii, Maui, and Kauai. Somewhat resembling M. phleoides, but smaller, and the spikes shorter. (M. & B. 246.)

518. FIMBRISTYLIS UMBELLATO-CAPITATA, Steud.? A very variable plant, from Waterlandt Island, Tutuilla, etc., as well as the Hawaiian Islands. The spikes are always sessile in a head, but the heads are solitary, or few, or numerous, subtended by 3-5 very short (or with one or two longer) awl-shaped bracts. The squamæ are ovate, acutish, concave, and somewhat keeled; the styles trifid and the stamens two; the achenia are less convex on one side than the other, threeangled and very obtuse at the apex. Probably not the species quoted, from which it differs in several particulars, but I am unable to identify it satisfactorily, though it must be well known.

Zeal., while, through some oversight, he refers M. gahniæformis to L. affinis, Brongn. (Gahnia arenaria, Hook. 1. c.), speaks of the Hawaiian

plant as a different but closely allied species; as it is. The character upon which Brown distinguished the genus Lamprocarya from Gahnia (that of not having a transversely grooved nut) only throws the most closely allied species into different genera.

525. GAHNIA BEECHEYI (sp. nov.): glaberrima; culmo tereti lævi; foliis linearibus longissimis superne filiformibus reclinatis arcte convolutis margine scabris dorso aculeis parvis asperatis; panicula (10-12pollicari) spicis axillaribus (sesqui- bipollicaribus) multifloris; bracteis ut foliis; bracteolis ovato-lanceolatis mucronatis, carina ciliata; spiculis unifloris; squamis ovato-lanceolatis acutis, intimis obtusiusculis ; nuce oblonga obscure trigona flava nitida styli basi cuspidata intus transverse sulcata. — On mountain ridges at 1,000 to 3,000 feet elevation. Apparently most nearly allied to G. schoenoides of Tahiti. (M. & B. 91; Remy, 136; Macrae.)

526. GAHNIA GLOBOSA (sp. nov.): glaberrima; culmo tereti lævi; foliis linearibus elongatis culmum superantibus convolutis subtus læviusculis, margine nervis supraque scabris; spicis globosis axillaribus e spiculis (18-25) unifloris arcte congestis compositis; bracteis e basi lata lanceolatis acuminatissimis; bracteolis ovato-lanceolatis acuminatis ; squamis late ovatis orbiculatisve acuminatis, intimis obtusis; nuce ovata flava extus longitudinaliter rugosa styli basi cuspidata intus haud sulcata. With the preceding. At once distinguished by the dense globose spikes in a short interrupted panicle, and the broadly ovate squamæ. Apparently often gathered by collectors, but by Hooker & Arnott confounded with Morelotia Gahniæformis, Gaud., and by others with Lamprocarya affinis, Brongn., &c. Probably identical with a poor specimen of Seemann's, no. 672, from the Viti Islands, which he has called L. affinis, Brongn. (W. T. Brigham.)

527. OREOBOLUS FURCATUS (sp. nov.): dense pulvinato-cæspitosus, ramosus, foliosus; foliis basi vaginantibus nervosis dense imbricatis lineari-subulatis acutis obtusiusculisve rigidis serrulatis; scapo sulcato terminali simplici vel furcato 1-4-floro; bracteis foliosis; bracteolis scariosis; perianthii foliolis ciliatis integerrimis. On the summits of the mountains of Maui and Kauai. Most nearly allied to O. obtusangulus, Gaud., from which it differs in its often several-flowered scape, in the leaves being serrulate, etc. (M. & B. 436; U. S. Expl. Exped.)

Graminea.

The Grasses being all in the hands of Colonel Munro, I cannot at present give a list of them. They show considerable novelty, and a large proportion are peculiar to the Group. There are about fifty species.

Mountains of Waimea, Kauai, 2,000 to 3,000 feet above the sea. This Fern is to be placed in the same group with M. gibberosa (Davallia gibberosa, Sw.), with which species it agrees pretty well in the position and form of the sori and involucres, though the black and shining

stipe and rhachis and the very narrow segments (about of a line wide) make it at once a very distinct and extremely elegant species." Eaton, mss. (M. & B. 546.)

I have never seen, nor do I know of P. geraniafolia occurring at the Hawaiian Islands.
