clenticulatis subtus ad venas venulasque ocliraceo-liirtellis utrinque se- 

 tulis basi papillatis asperis, petiolo miiricato ; calycis glabri lobis ovali- 

 bus obtusissimis foliaceis tubum elongato-obconicum £Equantibus ; corolla 

 2^-pollicari curvata. — Oahu. (Leaves of one or two seemingly allied 

 species were collected, Avitbout flowers or fruit.) 



3. Cyanea ? PiLOSA (sp. nov.) : caule frutescente ; foliis subpedali- 

 bus membranaceis obovatis utrinque acutis vel acuminatis eroso-crenatis 

 pilis brevibus moUibus hirsutis ; racemis brevibus in pedunculo 1-2- 

 pollicari birsutissimo paucifloris ; floribus " parvis griseo-cseruleis " pedi- 

 cellisque glabris ; lobis calycis linearibus foliaceis ovario oblongo aequi- 

 longis. — Mouna Kea, Hawaii. This and the preceding are doubtless 

 related to Chamisso's Lobelia calycina, ambigua, and pinnatifida, — ob- 

 scure species, referred by Presl and De Candolle to Delissea, but by 

 their foliaceous calyx-lobes apparently effecting a transition to Cyanea. 

 The next species, of which materials are also incomplete, is equally 

 ambiguous. 



4. Cyanea ? Rollandia {Rollandia crispa, Gaud. Lobelia caly- 

 cina, Cham. ?) : fruticosa ; foliis sesqui - tripedalibus obovato-lanceolatis 

 inferne longe attenuatis breviter petiolatis membranaceis fere glabris 

 margine serrulatis undulatis vel integerrimis ; pedunculo petiolum adae- 

 quante superne bracteato paucifloro ; floribus cinereo-puberulis ; calycis 

 lobis oblongis seu lanceolatis foliaceis ovario aiquilongis ; corolla sesqui- 

 pollicari ; fructu pyriformi poUicari. — Oahu. 



5. Cyanea tritomantha (sp. nov.) : caule simplici arborescente 

 orgyali ; foliis lato-lauceolatis membranaceis subintegerrimis fere glabris 

 basi acutis tripedalibus (incl. petiolo crasso 5 - 8-pollicari) ; floribus 

 " confertis " magnis ; calyce pubescente, lobis linearibus pollicaribus 

 foliaceis ovario cylindraceo longioribus ; corolla tripollicari extus tomen- 

 toso-pubescente in segmenta 3 longo-linearia mox divisa. — Mouna 

 Kea, Hawaii. 



6. Cyanea superba. Lobelia superba, Cham. Macrochilus super- 

 bus, Presl. — Oahu. 



7. Cyanea leptostegia (sp. nov.): glabra; foliis ad apicem cau- 

 lis simplicis arborei confertis lanceolatis subsessilibus integerrimis undu- 

 latis (bipedalibus et ultra) ; racemis brevissimis confertifloris ; calycis 

 segmentis praelongis e basi latiori angustissime linearibus patentibus 

 corolla gracili longioribus persistentibus. — Upper edge of the forest 

 near the tabular summit of Kauai. Calyx-lobes fully two inches long, 

 and, except at their broader base, less than half a line wide !
