685 PHANEROGAMIA. 



The Hawaiian plant is merely mentioned in Dr. Pickering's notes, 

 as if identical with that of Oahu. The only Hawaiian specimen in 

 the collection, — a fertile one with half-grown fruit, — differs from those 

 of Oahu, however, in having elongated-oblong leaves (6 to 8 inches in 

 length), all of them verticillate in threes. The fructiferous cyme is 

 more open; the ovoid ovary is free at its summit; the calyx being 

 adnate only to a little above the middle, its inconspicuous limb there 

 divided into 5, triangular and obtuse, appressed, very short teeth, 

 which are hardly discernible without a lens. Within and alternate 

 with these are as many similar teeth, of equal length, which repre- 

 sent the petals. Of stamens no vestiges are perceived. There is 

 properly no style; but the tapering apex of the fructified ovary is 

 contracted a little below the stigma ; the latter accords with the pre- 

 ceding species, as do the placentas, &c. Unless, therefore, Broussaisia 

 arguta is more variable than could be inferred without evidence, the 

 specimen before us must belong to a second species. — A recent com- 

 parison of our specimen with Gaudichaud's plate, cited above, leaves 

 no doubt that it belongs to his Broussaisia pdlucida, although the 

 plant figured by him has longer and narrower, and (judging from the 

 name) apparently much thinner leaves than ours, probably from 

 growing in deep shade. Further observation must determine whether 

 the characters assigned are constant, so as to specifically distinguish 

 the plant from B. arguta. This certainly cannot be the case if Gaudi- 

 chaud's figures 11 & 12, representing the fruit with a columnar style, 

 really belong to his B. pellucida. The young fruit in our specimen 

 answers to that of his figure B.
