on both sides, chartaceous to subcoriaceous, glabrous, densely punctate underneath slightly 

 pubescent along the salient midrib, prominently veined, the arcuate intramarginal nerve 

 somewhat distant from the edge of the leaf, rounded at both ends or retuse at the apex, 

 occasionally bluntly acute and mucronate, often subemarginate at the base, (i to 12 cm 

 long, 3 to 7 cm wide, on stout lignescent angular petioles of 3 to 2 cm; inflorescence a 

 cyme, axillary, usually in the axils of the lower leaves, single to 3 flowered, peduncle and 

 pedicels filiform, nodose, the former 6 to 10 mm long, the pedicels of variable length 2 to 3 

 cm, nodose, bibracteolate at each node, bracteoles linear-subulate pubescent; flowers large 

 in both sexes, female flowex's greenish yellow to red, strongly anise-scented as is the whole 

 plant, sepals ovate, acute, 3 mm, almost deltoid, petals linear-oblong, acute, 1 cm long, 

 glabrous as are the sepals, stamens rudimentary, as high as the ovary, the latter 1.5 mm. 

 glabrous; style slender filiform, 6 mm, or more, often protruding beyond the petals, 

 glabrous, with a four lobed stigma, the lobes slender oblong, 1 to 1.5 mm in length, 

 puberulous; male flowers as large as the female flowers or smaller ; petals broad, oblong, 

 acute, usually 12 mm long and 4.5 mm wide, glabrous, many nerved; stamens 8, 4 nearly 

 as long as the petals, the filaments broad, thin, and penninerved, the remaining 4, two- 

 thirds the length of the others, anthers oblong, deeply split at the base; ovary rudi- 

 mentary; style slender 3 mm, with a very indistinctly four notched, almost capitate 

 stigma; capsule nearly 5 cm transversely, and 18 to 20 mm high, somewhat chartaceous, 

 glabrous, the 4 follicles united half their length, in shape much like that of P. volcanica, 

 recurved, 1 to 2 seeded, rarely one or two abortive; endocarp loose, chartaceous, glabrous; 

 seed large, 9 mm long, ovoid to sub-orbiculir, black, shining. 



This exceedingly interesting species, which has been called the mokihana of 

 Hawaii, is a small tree or shrub, and is peculiar to the summit ridges and 

 swamps of the Kohala mountains on Hawaii. It occurs only at an elevation of 

 4000 to 5000 feet, and is exceedingly common at the summit of the Kohala range 

 called Kaala. It inhabits the dense rainforest where moss covers the ground 

 over a foot deep and where most beautiful 5-feet-high violets abound. When 

 bruised it emits an exceedingly strong odor of anise, much more so than the true 

 mokihana of Kauai, Pelea anisata. If a branch is bruised accidentally by work- 

 ing one's way through the jungle, the odor emitted can be detected for a long 

 distance through the forest jungle. The species has the biggest capsule in the 

 genus and also the largest flowers. 



The writer has excellent and most complete material of this species, which 

 seems to be related to P. oblongifolia, in all stages of growth. It was first col- 

 lected by the writer on July 13, 1909, flowering and fruiting, in the forests of 

 Kohala, no. 4455 ; it was again collected in June, 1910, in the same locality and 

 on the summit of Kohala proper, where it is most abundant in the swampy jungle 

 bordering a big open bog. Certain forms resemble somewhat Pelea parvifolia 

 Hbd. 



The type is no. 8306 in the College of Hawaii Herbarium and was collected at 

 the summit of Kohala, Hawaii. It also borders the edges of the great valleys of 

 Alakahi and Kawainui in the heart of the mountains at an elevation of 4200 

 feet, where they are enwrapped by clouds ten months or more of the year. 



Pelea Balloui Rock sp. nov. 



A small tree or shrub; leaves ovate or obovate rounded at both ends, occasionally 

 retuse at the apex, thick coriaceous, opaque, finely reticulated on both sides especially 

 underneath, the salient midrib reddish, pubescent, as is the under surface of the young 

 leaves, soon glabrate, the intramarginal nerve not distant from the edge of the leaf, 

 but with one set of meshes intervening 5 to 10 cm long, 3 to 7 cm wide, on petioles of
