wide, petioles of St) 3 em, pilates rounded a the apex or bluntly nay aikte 
oblong, contracting or cu eate toward the bas pag rictie except on the flat glands in the

length of panicle r even sad panicle w wide and spreading, often 12 em in inuies, 
of 3 to 4 whorls, ee ae 3 rays, whole inflorescence covered with a rufous pubescence,

This species, which is a tree 20 to 35 feet tall, oceurs 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 polymorpha, 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 em long, and the panicles 16 em long, ineluding 
the peduncle, while on the same tree some panicles are only 3 em long, but none 
are 8 mm as stated by Hillebrand. Collected flowering and fruiting Feb., 1912, 
(no. 10028). The flat cireular glands in the axils of veins, are well oe 
out in the accompanying plate (plate 186). 
Straussia Hillebrandii Rock sp. nov.

(Plates 187 and 188.) 
Leaves obovate oblong, enone at both ends, or cuneate the base, chartaceous to 
ovaccias glabrous and dark green above, but with a pee silat rufus pubescence under- 
neath, especially on the very prominent reddish m idrib and nerves, whose axils are entirely 
destitute of glands, so conspicuous in St. hawaiiensis, 10 to 15 em long, 6 to 9 em wide, 
on petioles of 10 to 45 mm; —— ovate- Rute acute, 12 mm long; panicles stout, 
rusty pubescent, large and open, 12 to 16 em long, 7 t o 10 em wide, erect or drooping, 
with 3 whorls, each with 4 to 6 rays which in pein branch “dichotomously aes free 264g ES

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 
voleano of Kilauea in the famous Kipuka Puaulu, which has er 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: * 
specimen, probably from the Kohala range, has the leaves rounded at the base
