Gesneriacece, Cyrtandrece. 



Of Cyrtandra hijiora, Forst., from Tahiti, the original of the genus, I 

 have nothing to remark. The species inhabiting the Sandwich Islands 

 I have been able to study under favorable circumstances ; the substance 

 of the revision is presented in the following analysis and diagnoses. 



CyrtandrcB Sandwicenses. 

 1. Flores mediocri, ultra-semipoUicares. 

 Folia cordata, ampla. 



Calyx rotatus, lobis ovatis : ovarium villosum. C cordifolia. 



Cah'x campaniilatus, lobis lanceolatis : ovarium glabrura. C. platyphylla. 



Folia utrinque acuta vel acuminata. 



Calyx crateriformis breviter 5-lobus. C. Piclceringii.

Calyx 5-partitus : folia utrinque viridia. Var. lysiosepala. 



Calyx 5-partitus : folia subtus ferruginco-scricea. C. Lessoniana. 



2. Flores parvi, baud semipollicares. 

 Folia elliptica, subtus cancscenti-velutina: calyx 5-fidus. C. Garnotiana, 



Folia lato ovata, subtus pruinoso-canescens ; calyx 5-partitus, lobis

Folia utrinque viridia, oblonga seu lanccolata : calyx 5-partitus, 



lobis setaceis elongatis. C. Menziesii. 



Cyrtandra cordifolia (Gaud.) : villosissima ; foliis rotundo- 

 ovatis cordatis acuminatis argute dentatis supra hirsutis subtus calyci- 

 busque dense tomentoso-villosis subincanis (5 - 7-poIl.) ; pedunculis 

 plurifloris ; calyce rotato angulato-quinquefido fere a?quali corollam 

 suba^quantibus, lobis late ovatis acuminatis ; ovario cum stylo brevis- 

 simo villoso. — Oahu. Gaudichaud's plate pretty well represents this 

 species, except that the shaggy pubescence is omitted, the leaves are 

 not large enough, and the rotate calyx not expanded. 



Cyrtandra platyphylla (sp. nov.) : foliis subrotundo-cordatis 

 breve acuminatis (5-9 poll, latis) argute denticulatis supra hirsutulis 

 subtus canescenti-pubescentibus, costis cum petiolis ramis calycibusque 

 pube ferruginea villosis ; pedunculis plurifloris ; calyce ina^qualiter 

 quinquefido, lobis lato-lanceolatis corolla brevioribus ; ovario cum stylo 

 gracili glaberrimo. — Hawaii, in forests. Stem 10 feet high. 



Cyrtandra Pickeringii (sp. nov.) : ferrugineo-villosa ; foliis ob- 

 longo-lanceolatis utrinque acuminatis subserrulatis supra hirsutis subtus
