 2.5 cm. in diameter at point of attachment of the petiole, the pulvinus 

 of which is also hairy. Staminal tube 9 to 10 cm. lung, curved. Seeds

KOKIA DRYNARIOIDES (Seemann) Lewton, now comb. 



Gossypium drynarioides Seemann, Fl. Vit., 1865, p. 22. 



Hibiscus drynarioides Kuntze, Rev. Gen. PI., 1891, vol. 1, p. 68. 



With the exception of the calyx, this species is adequately de- 

 scribed in Hillebrand's Flora of the Hawaiian Islands. A frag- 

 mentary specimen in the Gray Herbarium of Harvard University, 

 collected by Dr. Hillebrand, and identified as G. drynarioides, has the 

 narrow bracts of his " variety " here described as Kokia lanceolata ; 

 while an immature capsule in a pocket attached to the sheet has the 

 broad, almost cordate bracts of the typical form which the writer 

 considers as representing Kokia drynarioides. The same herbarium 

 contains a sheet representing Remy's No. 568 from Molokai, evi- 

 dently from a diseased tree. The involucral bracts are smaller than 

 in Hillebrand's specimen, but are as broad as long. 



The U. S. National Herbarium, contains two sheets of this species. 

 The first, consisting of two scraps, represents Hillebrand's No. [921, 

 no locality being given. The second specimen, consisting 1 f a branch 

 and two mature capsules, was collected at Mahaua, tsland of Molokai, 

 by J. F. Rock I No. 7076) April, 1910. The latter specimen has 

 leaves which are glabrous below except for a few brownish hairs at 

 the base of the veins.
