Rutaceae. 



This rather interesting species, called Uahe a Pele by the natives, meaning 

 smoke of Pele, owing to the peculiar smoky gray color of the leaves, is only found 

 on the Island of Kauai, where it inhabits the drier districts especially near Ka- 

 holuamano and Halemanu, above Waimea, at an elevation of 3600 to 4000 feet. It 

 is a rather small tree or often only a shrub. It is quite different from Pelea 

 cinerea in general aspect as well as in the leaves, which are thinner and curved, 

 and mainly in its fruits, which are glabrous, and have also a glabrous endocarp. 

 It comes, however, nearest to that species, though specifically distinct from it and 

 not a mere form, as Wawra tried to make out.

A small tree; leaves thin chartaceous, with pellucid dots, elliptico-oblong 7.5 to 12.5 

 cm long, 2.5 to 3.5 em wide, on petioles of 8 to 16 mm, broadly obtuse or rounded, even 

 emarginate at both ends, faintly nerved, with the sinuous marginal nerve rather distant 

 from the edge, sparsely dotted underneath with a pale pubescence, but soon glabrous 

 and pale; flowers 1 to 3 on a short angular peduncle of 2 to 6 mm, the pedicels 6 mm, 

 bracteolate below the middle with dentiform bractlets; sometimes several cymes in one 

 axilla; sepals and petals coriaceous, persistent below the capsule, both canescent in the 

 bud, but sub-glabrate in a later period; sepals 2 mm, obTuse, petals valvate in the bud, 

 oblong 3 to 5 mm; style obscurely 4-lobed, almost capitate in the sterile flowers; follicles 

 discreet to the base, gray, puberulous, 8 to 10 mm, thin papery, dehiscent in both sutures, 

 one or more abortive. 



The plant was first collected by the U. S. Exploring Expedition on Kaala of the 

 Waianae range. Island of Oahu. The writer is not familiar with this species, as 

 he has never collected it. Hillebrand describes five varieties of this species, two 

 from Maui, one from Niu Valley, Oahu, and the last var. c. from Kalae and 

 Mauna Loa, Molokai.

Young shoots covered with a grayish or ochraceous tomentum; leaves opposite, ovate 

 oblong 7.5 to 10 cm long, 3.75 to 5 em wide, on petioles of 16 to 24 mm, shortly acuminate,, 

 subcoriaceous, with faint nerves, the marginal nerve distant and arcuate, tomentulose to 

 pubescent underneath, glabrate when old; flowers 3 to 5 in a short cyme or raceme, thp- 

 angular peduncle 6 to 12 mm, the pedicels 4 to 8 mm, bibracteolate at the middle; petals 

 4 mm, valvate in the bud, but some edges forced out before expansion, gray puberulous; 

 ovary tomentose; capsule 20 to 24 mm transversely, the follicles cohering slightly at the 

 base only, soon glabrate, thick coriaceous, opening only along the ventral suture, gener- 

 ally all maturing; the thick endocarp pubescent; seeds 1 or 2 in each follicle, 4 to 6 mm 

 in diameter; cotyledons plano-convex, extending the whole length and breadth of the 

 albumen.
