on the strength of the new material, the specifie description is herewith enlarged. 
It is one of our most interesting species of Pelea in that it has the greatest 
number of flowers in its inflorescence, bearing often more than 200 flowers. It 
belongs to the same group as Pelea cinerea and Pelea barbigera, though it is spe- 
cifically very distinct from both. At Auahi, to which place this tree is peculiar, 
it is associated with Alectryon macrococcus, Pterotropia dipyrena, Bobea Hookeri, 
Alphitonia excelsa, Sideroxrylon auahiense, Antidesma pulvinatum, ete.

The plant was collected by Valdemar Knudsen - Kauai, for whom it was 
named by Hillebrand. It is recorded as growing at an elevation of 1500 feet 
back of Waimea, Kauai, and is, of course, a dry district plant. It is not known 
to the writer, who collected extensively in the above referred to locality, but 
never met with this species. It is evidently closely related to the writer’s Pelea 
multiflora, which differs, however, from the foregoing in the exceedingly large 
inflorescence, which is 15 em long, in the 6 em long peduncle, and in the number 
of flowers, which is up to 200; the ovary in this species is glabrous. 
The capsule of P. Knudsenii is not known, but is unquestionably apocarpous, 
under which latter heading it is placed in Hillebrand’s key to the species.
