Rubiaceae. 



Leaves thick, chartaceous, with stout nerves, obovate 10 to 18 cm long. 5.5 to 8.5 cm 

 wide, petioles of 1.5 to 3 cm, somewhat rounded at the apex or bluntly acute, obovate 

 oblong, contracting or cuneate toward the base, glabrous, except on the flat glands in the 

 axils of the nerves, which are usually large and pubescent; midrib impressed above, reddish 

 underneath, stipules triangular, obtuse, 6 mm; peduncles from 16 mm to 8 cm long, whole 

 length of panicle 16 cm or even more, panicle wide and spreading, often 12 cm in diameter, 

 of 3 to 4 whorls, of usually 3 rays, whole inflorescence covered with a rufous pubescence, 

 calyx truncate; corolla 3 to 4 mm, the 4.5 lobes as long as the tube or little longer 

 each with a patch of hairlets at the base; drupe obovoid, small, 6 mm or less, crowned 

 by the truncate limb of the calyx. 



This species, which is a tree 20 to 35 feet tall, occurs in the forests of South 

 Kona, Hawaii, on the slopes of Mauna Loa, especially in the more uniform for- 

 ests above the lava fields of Kapua at an elevation of 3000 feet; the trunk is 

 about one foot in diameter and vested in a smooth black bark. It is associated 

 with Metrosideros polymorplia, Myoporum sandwicense, Xylosma Hillebrandii, 

 Clermontia coerulea, and others. Hillebrand's description of the tree- is not 

 quite correct: he says: "panicles as in No. 2," (Straussia Mariniana). This latter 

 species however has panicles only 4 lines long according to his description, while 

 St. hawaiiensis has exceedingly large panicles. Gray's description of this 

 species is too vague to permit a certain diagnosis. However the plant figured 

 (plate 186) is none other than St. hawaiiensis and was collected in the type 

 locality. The leaves are over 18 cm long, and the panicles 16 cm long, including 

 the peduncle, while on the same tree some panicles are only 3 cm long, but none 

 are 8 mm as stated by Hillebrand. Collected flowering and fruiting Feb., 1912, 

 (no. 10028). The flat circular glands in the axils of veins, are well brought 

 out in the accompanying plate (plate 186). 



Straussia Hillebrandii Rock sp. nov. 



Kopiko. 

 (Plates 187 and 188.) 



Leaves obovate oblong, rounded at both ends, or cuneate at the base, chartaceous to 

 coriaceous, glabrous and dark green above, but with a scattered rufus pubescence under- 

 neath, especially on the very prominent reddish midrib and nerves, whose axils are entirely 

 destitute of glands, so conspicuous in St. iHiinii'u'iixiK, 10 to 15 cm long, 6 to 9 cm wide, 

 on petioles of 10 to 45 mm; stipules ovate-oblong, acute, 12 mm long; panicles stout, 

 rusty pubescent, large and open, 12 to 16 cm long, 7 to 10 cm wide, erect or drooping, 

 with 3 whorls, each with 4 to 6 rays which in turn branch dichotomously, the free peduncles 

 6 to 10 cm long; calyx dentate to subtruncate, subglabrous; corolla 3 mm, the 4 lobes 

 longer than the tube, puberulous inside, anthers partly exserted, style exserted, with two 

 long clavate stigmatic branches; drupe small, obovoid, 6 mm, crowned by the minute 

 dentate calyx-limb. 



This new species of Kopiko, named in memory of Dr. W. Hillebrand, occurs 

 on the Island of Hawaii, on the slopes of Mauna Loa, only 3 miles from the 

 volcano of Kilauea in the famous Kipuka Puaulu, which has already furnished 

 a number of new species and even a new genus. 



The species comes close to Straussia hawaiiensis in one way and in the other 

 to St. oncocarpa. Hillebrand, in a foot note under St. Hawaiiensis says: "A 

 specimen, probably from the Kohala range, has the leaves rounded at the base
