calls for a small capsule, while these are large. ' ' But had Heller seen the original 

 description he would have noticed Mann 's remark, ' 'Ripe fruit unknown, ' ' which 

 accounts for his capsules being small, as they were not fully developed. The 

 writer has abundant fruiting material in which the capsules are of various sizes 

 from 12 mm to over 30 mm in diameter. Collected Halemanu flowering and 

 fruiting February 14, 1909, no. 2292, and Kaholuamano, September, 1909, no. 

 5292, and fruiting October, 1911, no. 10214 in Herbarium, College of Hawaii.

From within 5 minutes walk of the summit of Kauai, Mt. Waialeale, the writer 

 collected a specimen of a Pelea which must be referred to this species ; it is, how- 

 ever, a small stunted shrub, but answers otherwise the description of P. Kauai- 

 ensis. The capsules are much larger and all cocci are fully developed ; the diam- 

 eter of the mature capsule is 3.5 cm. Collected September 24, 1909, Waialeale, 

 Kauai, 5000 feet elevation, no. 4990. 



Hillebrand reports a variety /?. glabra, from the same locality with glabrous 

 leaves which are on longer petioles; perhaps the writer's no. 1994 from Hale- 

 manu, without flowers or fruits.

A small tree or shrub, leaves sessile or subsessile, orbicular to ovate, rounded and 

 emarginate or acute at the apex, cordate at the base, thick coriaceous, prominently nerved 

 below, the intramarginal nerve arched, distant from the edge, with intervening meshes 

 entirely glabrous 6 to 12 cm long, little less wide, flowers several in a short peduneled 

 somewhat racemose cyme in the axils of the upper or occasionally lower leaves; bracts 

 and bractlets opposite, minute, ovate, subulate; male flowers: sepals ovate, acute, puberu- 

 lous, 4 mm high, petals more than twice the length, oblong, acute, glabrous; stamens 8, 

 4 longer than the petals, protruding, the remaining ones shorter and of unequal size, on 

 broadened filaments; anthers sagittate, acute; rudimentary ovary pubescent, four lobed, 

 pubescence encroaching on the lower part of the style, which is 2 mm in length and ter- 

 minates into a bluntly 4 lobed stigma; female flowers shorter, about half the length of 

 the male flowers, petals slightly longer than the sepals, the 8 stamens not longer than the 

 ovary; ovules 2 in each cell; fruit nearly as in Pelcti rolcinii.ra, but smaller, minutely 

 pubescent, the carpels united at the base. 



This peculiar species can be found not uncommon in the mountains back of 

 Honolulu, and is easily recognized by its rather large sessile cordate leaves, and 

 rambling or long drooping branches. Wawra quite correctly remarks that the 

 otherwise excellent figure shows undeveloped flowers ; the detailed drawings rep- 

 resent female flowers, so does Gray's description, as he had not seen the much 

 larger male flowers. It is peculiar to Oahu and occurs throughout the main 

 Koolau range at an elevation of 2000 to 2500 feet.
