Zephyritis Taitensis. The common Hawaian species having been 

 dedicated to a celebrated king of those islands, this may bear the name 

 of the gentler Tahitian queen, Pomare. 



The various forms from the Sandwich Islands, including one of the 

 Society Islands, appear to be reducible to two species : — 



Cyathodes Tameiamei^ (Cham.) : fruticosa ; foliis patulis ob- 

 longis cuneato-obovatis linearibusve sjepius abrupte mucronatis mar- 

 gine ad apicem ciliolatis subtus glaucis multinervibus, nervis ssepius 

 ramosis, floralibus parvis ; sepalis bracteolisque orbiculatis ciliolatis ; 

 corollae tubo calycem baud excedente, lobis aut barbatis aut imberbi- 

 bus ; stylo crasso ovario 5 - 8-loculari aequilongo. 



Var. a. Chamissoi (C Tameiameice, Cham., Hook. & Arn., DC.) : 

 corollae lobis intus pi. m. barbatis. — Oahu, &c. 



Var. /3. Brownii (C. Banhsii (Gaud.?) & Macrceana, T>C) : co- 

 rollfe lobis imberbibus. — Maui, Kauai, and especially Hawaii. 



Var. y. SociETATis : corollae lobis intus parcissime barbatis ; foliis 

 plerisque linearibus. — Eimeo, and probably Tahiti. — This is most 

 probably the Tahitian plant mentioned by Brown ; while to our var. /3 

 may belong both the Sandwich Island species to which he alludes. 



Cyathodes Douglasii (sp, nov.) : fruticosa ; foliis suberectis ob- 

 longis seu lanceolatis acuminato-cuspidatis margine plerumque his- 

 pidulo-ciliolatis subtus pallidioribus vel glaucis 5 - 9-nervibus, nervis 

 saepissime simplicissimis ; sepalis bracteolisque ovatis obtusis ciliatis ; 

 corollae tubo calycem jequante, lobis intus barbatis ; stylo subulato 

 ovario 6-loculari bis terve longiore. — Hawaii, on Mouna Loa and 

 Mouna Kea ; also Maui, on Mouna Haleakala. 



Var. /3. STRUTHiOLOiDES : foliis erectis lanceolatis seu ovato-ob- 

 longis ; sepalis acutis ! Mouna Kea, high in the pastoral region ; and 

 perhaps a form on the mountains of Kauai, without flowers or fruit. 



None of the various specimens here combined accord with the C. 

 Banksii so imperfectly characterized by De Candolle. For, although 

 the leaves are more or less ei*ect, and rarely glaucous-white beneath, 

 they are rough and ciliolate or serrulate on the margins, and with 

 a pungent point ; their nerves usually all simple. Also the larger 

 flowers and longer style should distinguish all forms of this from the 

 preceding species, unless that is even more polymorphous than I have 

 supposed. As to the style in this and allied species, I should rely more 

 upon it if I did not entertain some suspicion of dioecio-dimorphism in the 

 genus.
