Professor Gray presented the following paper : — 



Notes upon some Paihiacece^ collected in the South Sea Explor- 

 ing- Expedition under Captain Wilkes. By Asa Gray, M. D. 

 (Continued from April, 1858 : vide p. 50.) 



CopROSMA CALTCiNA : herbacea, repens, fere glabra ; foliis ovato- 

 rotunclis ciliolatis breviter petiolatis ; stipulis obsoletis ; floribus sub- 

 solitariis subsessilibus 4 - 5-meris ; calycis lobis ovato-lanceolatis foli- 

 aceis ovario obovato fequilongis corolla tubulosa vix dimidio breviori- 

 bus. Hedyotis repens, Clos in Gay, Fl. S,p. 208. — Chili, comnion in 

 the province of Yaldivia, &c., C. Gay. — It is odd that this jilant, 

 Laving been correctly described, except that the dry drupe is called a 

 capsule, should yet have been mistaken for a Hedyotis. It really forms 

 a connecting link between Nertera (of which it has the habit) and Go- 

 prosma ; but is peculiar for its large calyx-lobes, which persist on the 

 young fruit. According to Clos, it is monoecious or dioecious, which, 

 with the developed lobes of the calyx, would fix the plant in Coprosma. 

 But the only flower upon my specimen is hermaphrodite ! 



7. Corrections and Additions to the former article. 



Psycliotria parvida, p. 13, is only a form of P. seypens, Linn., as ap- 

 pears upon a comparison with specimens from Hong Kong, and from 

 the Loo Choo and Bonin Islands. 



P. turhinata, p. 12. — Mr. Bentham has distributed No. 2086 of 

 Spruce's Amazon collection under the same name ; but as the flowers 

 of that plant seem equally to be unknown, it may be best to retain 

 the name for the Feejean species, which can hardly be any else than 

 a Psycliotria. 



Among some Polynesian RuliacecB, collected by Mr. Milne in the 

 recent cruises of the Herald, British surveying vessel, and placed 

 in my hands by Dr. Hooker, I notice two species which may be 

 referred to the genus Galycosia, p. 15, although their flowers are in 

 loose cymes : — 



Calycosia pubiflora (sp. nov.) : foliis membranaceis glabris 

 oblongo-lanceolatis acuminatis in petioluin attenuatis (4 — G-poll. longis) ; 

 cyma laxa trichotoma calycisque tubo viscoso-pubescentibus, limbo cra- 

 teriformi extus puberulo ; dnipa turbinata, pyrenis chartaceis intus 

 excavatis. — Viti-levu, Feejee Islands, Mr. 3Iilne. — Limb of the calyx 

 apparently white, half an inch in diameter. Corolla hardly exserted.
