latis ; pedunculis axillaribus brevibus crassis paucifloris; pedicellis sub- 

 poUicaribus nudis ; lobis calycis brevibus subulatis ; floribus fere bipol- 

 licaribus. — Puna, Hawaii, in woods near Hilo. (M, & B.) 



266. Delissea RACEMOSA (sp. nov.) : fruticosa ; foliis oblongo-lan- 

 ceolatis vel ovato-lanceolatis utrinque acutis minute eroso-crenulatis in 

 petiolum brevem longe attenuatis, supra pilis conicis brevibus raris, sub- 

 tus albidis pubescentibus venis brunneis ; pedunculis folium adajquanti- 

 bus bracteatis ; pedicellis bracteolatis ; calycis lobis glabratis oblongis 

 obtusiusculis ovario multo brevioribus. — Oahu. — An unbranched 

 shrub, 5 or 6 feet high. Leaves a foot long, about 4 inches wide, 

 tapering gradually at the base into a petiole but an inch long. The 

 pubescence on the under surface of the leaf whitish, except on the 

 brown veins, and quite characteristic. Peduncles loosely several-flow- 

 ered. Ovary 6 or 7 lines long. Sepals hardly exceeding a line in 

 length. (M. & B.) 



267. Delissea caltcina (Presl. Prodr. Lob. p. 47) : foliis ob- 

 longo-lanceolatis utrinque acutis in petiolum brevem louge attenuatis 

 in^equaliter eroso-crenulatis supra planis pilisque conicis brevibus raris 

 sparsis conspersis subtus reticulato-venosis in rete fuscescente prsesertim 

 hirtis ; calyce glabro, lobis oblongis obtusiusculis uninerviis ; ovario sub 

 anthesi obconico, grossificatione olivosformi, vertice lobis calycis erectis 

 coronato ; corolla limbo hirtella ; tubo antherarum circa basin sursum- 

 que in sulcis hirto. Lobelia calycina, Cham, in Linniea, 8, p. 222. — 

 Leaves crenulate, shining above, li feet long, 3 inches wide. Petiole 

 1 inch long. In some notes which Prof. A. Braun has obligingly 

 communicated concerning Chamisso's specimen of this plant in the 

 Berlin herbarium, he shows that the common peduncle is but an inch 

 or two long, much thickened, and that the sepals are ovate-lanceolate, 

 3 lines long and half as wide. It thus differs in several respects from 

 the preceding species, which I had at first thought should be referred 

 here, but I am not so sure now that this species should not stand in 

 Cyanea, and near C aspera. Gray. 



268. Delissea pinnatifida (Presl. 1. c. p. 47) ^: ramosa; foliis 

 oblongo-lanceolatis utrinque acutis in petiqlum brevem decurrentibus 

 remote pinnatifidis leviter sinuato-duplicato-dentatis, dentibus brevibus 

 pinnisque obtusis calloso-mucronu latis, supra planis glabris, subtus 

 reticulato-venosis in rete fuscescente pra5sertim hirtis ; racemis axil- 

 laribus ; calycibus coroUisque hirtis ; ovario obconico lobis calycis auri- 

 culatis ovatis obtusis coronato. Lobelia pinnatijida, Cham, in Linntea, 

 8, p. 220. — Oahu.
