acutis longiiiscule petiolatis, venulis conspicue reticulatis ; racemis plu- 

 rifloris petiolum baud superantibus ; calycis bmbo obsolete seu dentibus 

 5 minutis instructo ; corolla pollicari subcurvata. — Kauai, Remy. 



Var. j3. foliis spatliulato-lanceolatis in petiolum brevem longe attenu- 

 atis. — Crater of East Maui. Fruit as large as a cherry. 



5. Delissea obtusa (sp. nov.) : suffruticosa ; ramis junioribus 

 floribusque undique pubescentibus ; foliis (5 — 6-pollic.) membranaceis 

 oblongis serrulatis apice vel utrinque obtusis subtus parce pubescentibus ; 

 racemis plurifloris petiolum gracilem baud superantibus ; calycis limbo 

 fere obsoleto ; corolla gracili subpoUicari incurva. — Mountains of Maui. 



Var. ? MOLLIS : caule crassiori ; foliis elongatis (subpedalibus) ob- 

 longo-lanceolatis basi in petiolum breviusculum attenuatis supra pube- 

 rulis subtus molliter pubescentibus ; " floribus pollicaribus crassiuscu- 

 lis cairuleis." — Mouna Kea, Hawaii. — Possibly both may be varieties 

 of the following. 



6. Delissea acuminata, Gaud. Bot. Freyc. p. 457, t. 70. — Oahu. 

 Var. ANGUSTIFOLIA : foliis elongato-lanceolatis aut angustatis aut 



latiusculis. D. {Lobelia) angiistifolia, Cham., DC. — Oahu. 



7. Delissea undulata, Gaud., to which belongs D. suhcordata of 

 the same work ; leaves with the base subcordate, obtuse, or acute being 

 found on the same stem. The small protuberances on the tube of the 

 corolla represented by Gaudichaud occur in all the forms, but ai*e in- 

 constant. 



8. Delissea ? PLATyrnvLLA (sp. nov;) : caule fruticoso orgyali 

 petiolisque tuberculis aculeisve conicis moliibus obsitis; foliis sesqui- 

 bipcdalibus obovato-oblongis repandis membranaceis glabris ; peduncu- 

 lis axillaribus brevibus crassis paucifloris : lobis calycis glabri brevissi- 

 mis subulatis. — District of Puna, Hawaii. The port is rather that of 

 Cyanea, and the resemblance to Gaudichaud's RoUandia crispa is not 

 remote. 



To Cyanea, Gaud., distinguished by the foliaceous or enlarged and 

 persistent lobes of the calyx, I refer all the following : — 



1. Cyanea Grimesiana, Gaud. 1. c. t. 75. — Oahu. The corolla is 

 variously stated to be " bluish rose-color," or " white striped with red- 

 dish-purple externally." 



Vai". ? CITRDLLIFOLIA : foHis bipinnatipartitis, segmentis sinuatis ; 

 caule aculeis conicis creberrimis horrido. — Mouna Roa and Mouna 

 Kea, Hawaii. Flowers unknown. 



2. Cyanea aspera (sp. nov.) : foliis oblongo-ovatis acuminatis
