Straus SI A Kaduana : foliis subsessilibus cuneato-obovatis, juniori- 

 bus subtus ad costas cum pedicellis calycibusque stepissime ferrugineo- 

 pilosulis ; corolla? fauce imberbi ; drupa pyriformi subquadrangulata. 

 Coffea Kaduana, Cham. ^ Schlect. in Linncea, 4, p. 33 ; DC. Prodr. 4,

 Apionema obovata & A. penduliflora, Nutt. in Herb. Hook. — Oahu, 

 Sandwich Islands. — The thin fissure in the axis of the albumen is 

 symmetrical, not lined with a membrane, and not owing to an infolding, 

 like that of a coffee-grain. — It is questionable whether the throat of 

 the corolla is always naked, and whether the second species is distinct 

 from the present. The five bearded spots certainly exist in the Coffea 

 Chamissonis of Hooker and Arnott, although they were overlooked 

 (they are never so conspicuous as vsrould be inferred from Chamisso's 

 description) ; hence that is to be referred to 



Straus siA IVIariniana : tota vel fere glabra ; foliis breviter seu 

 brevissime petiolatis obovato-oblongis ellipticisve ; corolla? fauce inter 

 stamina breviter barbata ; drupa obovato-pyriformi. Coffea Marini- 

 ana, Cham. c3- Schlect. I. c. ; D G. I. c. C. Chamissonis, Book. 8^ Am. 

 Apionema sulcata, Nutt. in Herb. Hooh — Oahu, Sandwich Islands. 



Straussia Hawaiensis (sp. nov.) : foliis longius petiolatis obovatis 

 calycibusque glaberrimis ; coroUte fauce inter stamina barbata ; drupa 

 parva ovoidea vel obovata. — Hawaii, Sandwich Islands. — The con- 

 spicuously petioled and usually large leaves, and the small fruit (only 

 three, instead of six or seven, lines in length), distinguish this species 

 from the preceding. 



The following species of Ghasalia approach Psychotria. 



Chasalia Amicorum [Gray, I.e.): glaberrlma ; stipulis vaginan- 

 tibus ; foliis oblongis ovalibusque basi acutis, venis primariis 6 - 8 ; 

 cyma laxiflora breviter pedunculata ; calycis tubo ultra ovarium obo-
