Leaves impari-pin sec ios 9 dm rire peo es? 11 = 21, ovate oblong, 7 to 19 em 
long, 4 to 8 em wide, S petinten of 2 to 15 mm (the 1 upper pair of leaflets ot 
Sessile in some specimens, the lowest pair of ‘leaflets satak smaller than the others, but 
on the longest pétioluies): seuatiate or rounded at the apex, rounded or truncate * the 
base, coriaceous, sprinkled above, densely mongers underneath; panicle large and 
ample, its 5 primary branches 1 to m long mostly alternate on a common Bidovcsie of 5 to 
“7 em, the secondary branches 4 ef x em, mostly aitennais: ie als 6 to 7, rarely 9, esrag 
tomentose especially in the bud; ovary generally 4- celled, or 3 to 5 celled, stigmas o 
distinet stylopod of 1 mm; drupe arent about 12 mm, ringed below, at, or above the middle, 
he pyrenae chartaceous. 
This species differs very little from P. dipyrena, and is only distinguishable 
from the latter in the raised stigmas, the number of which is usually four in 
P. kavaiensis and two to three to four in P. dipyrena. The characters of the 
leaves can not at all be relied upon, the leaflets of P. dipyrena varying from 
linear oblong to ovoid, and are either cordate, truncate or rounded at the base, 
on petiolules of about 1 mm to 30 mm; the stigmas are more or less sessile in 
P. dipyrena. 
Pterotropia kavaiensis, in the writer’s mind, should be united with P. dipy- 
rena, but as only one good flowering specimen from one locality is at present in 
his possession, he defers such action until the future, when more complete mate- 
rial shall be at hand. 
The Ohe ohe of Kanai is a very beautiful and symmetrical tree reaching a 
height of 50 feet and occasionally more, with a trunk of over one foot in diam- 
eter. It divides near the top into a few ascending stout branches, at the end of 
which are large leaf-whorls. The crown is flat and is about one-fifth the height 
of the tree. When growing, crowded by other trees, it branches 10 or 15 feet 
above the ground and is not as symmetrical as trees growing apart. It is a tree 
which inhabits the mountains on the leeward side of Kauai, above Waimea, in 
the dry regions at an elevation of 2800 to 4000 feet. 
Its associates are Bobea Mannii, Cryptocaria Mannii, Cyanea leptostegia, 
Tetraplasandra Waimeae, Metrosideros, ete. It ean be recognized from afar, as 
it usually towers above the trees surrounding it, giving the landscape a peculiar 
aspect. 
The wood of the Ohe ohe is white and rather soft.
