Rubiaceae. 



corolla waxy white, funnel shaped, villous at the tliroat, 6-lobed; anthers subsessile at the 

 throat, acute, little exserted; style slightly exserted, the short lobes dilated; drupe 12 mm 

 crowned with the calyeine limb; pyrenae with 3 ridges at the back. 



This species, for which there is no native name as far as can be ascertained, 

 was originally discovered on Kauai. It was however found by the writer on the 

 Island of Oahu, in the forests of the Koolau range. It is a small tree 15 to 20 

 feet in height and occurs along the Manoa cliff trail back of Honolulu, as well 

 as in the forest of Punaluu, on the windward side of Oahu. The flowers of this 

 species are white and much larger than those of Straussia (Kopiko). 



On Kauai in the mountains of Kaholuaniano and Halemanu occur two other 

 species, one of them a small tree, first described by Wawra as a variety hirta 

 of the above species, but raised since to specific rank by Heller and now known 

 as Psyclwtria Jiirta (Wawra) Heller. It differs from P. liexandra in the leaves, 

 which are obovate cuneate at the base and pubescent underneath; the calyx 

 teeth are also shorter. The third species, Psycliotria grandiflora Mann, is a 

 shrub and was collected by the w r riter in the swampy forests of Halemanu near 

 Alakai swamp. It is the handsomest species, as it has the largest flowers, which 

 are pure white to cream colored on long drooping panicles. Hillebrand records 

 it as a tree, but it was observed by the writer only as a shrub. 



COPROSMA Forst. 



Flowers unisexual, dioecious in all Hawaiian species. Calyx cup-shaped, truncate or 

 more or less toothed or lobed, larger in the female flowers than in the male. Corolla 

 funnel-shaped or campanulate 4 to 9 lobed, lobes in the female flowers often reflexed. 

 Stamens 4 to 9 inserted at the base of the corolla-tube, exserted. Ovary 2, very rarely 

 4-celled; style divided to the base, pubescent. Drupe ovate or globose, fleshy. Prostrate 

 or erect shrubs or trees with opposite or rarely verticillate leaves, entire or dentate stipules. 

 Flowers white or greenish, quite inconspicuous, single or in few flowered cymes, terminal 

 or axillary. 



The genus Coprosma, which consists of about 45 to 50 species, of which the 

 majority are found in New Zealand, has quite a number of species in the Ha- 

 waiian Islands. So far 15 species have been found in these islands, of which 4 

 were described lately, two by the present w*riter in this volume and two by 

 H. Leveille in Fedde repertorium (C. Fauriei and C. parvifolia). The latter 

 was first collected by the writer on West Maui, while Faurie's specimen came 

 from Molokai. C. Fauriei is not a good species and is referable to C. Kauaiensis 

 (Gray) Heller. A few species occur in the Fiji and Norfolk Islands, 8 in 

 Australia, 1 in the Malay Peninsula, and 1 or 2 in Chile. 



None of the Hawaiian species has a foetid odor, as the generic name would 

 imply.
