1. Combretum farinosum; scandens, foliis oppositis obovato-oblongis obtusis utrinque

 subsecundis octandris aurantiacis, fructibus oblongo-pyriformibus tetrapteris. H.B.K.

Hab. Realejo. This seems to have a wide range along the coast of the Pacific, from Acapulco to Realejo. — 

 We think we are right in referring this plant to C. farinosum, but there are some points of difference which 

 we observe in our specimens, which are in much finer condition in the present Mexican collection than in the 

 previous one. It is a very splendid species ; the stems and branches long and very woody. Petiole three 

 quarters of an inch long. Leaves opposite, broadly elliptical rather than obovate, moderately acute at each 

 extremity, between membranaceous and coriaceous, quite entire, indistinctly squamuloso-farinose above, 

 decidedly so beneath, though not very evident to the naked eye : seen under the magnifier the little scales or 

 farina appear white and round. Racemes as frequently lateral as terminal, 4-G inches and more long, the 

 rachis firm and woody. Peduncle short. Flowers very numerous, crowded, deflexed and pointing to one 

 side. Pedicel (or rather pedicelliform ovary) the third of an inch long, tetragonal, mealy ; free portion of the 

 calyx cup-shaped, tapering at the base, mealy, 4-lobed, lobes acute. Petals 4, alternating with the lobes of the 

 calyx, and situated at the hairy mouth of the calyx, very minute, squamiform. Stamens 8, much protruded, 

 four times as long as the calyx. Filaments deep crimson, arising from the mouth of the calyx. Anthers 

 orange-colour, oval-oblong. Capsules about three quarters of an inch long, roundish-rhomboidal, with 4 

 broad, membranaceous wings : the surface is almost destitute of the mealiness which clothed the ovary. 



Schiede says the Combretum farinosum is called " Peyna," signifying a comb, by the Spaniards of Acto- 

 pan, probably because of the closely placed one-sided flowers of the raceme. 



Ord. XVI. ONAGRARIEiE. Juss. 



1. Jussieua peploides ; fruticulosa glabra, foliis spatbulato-oblongis obtusis crassiusculis, 

 floribus decandris, pedunculo nudo, laciniis calycinis lanceolatis acuminatis, capsulis 

 linearibus. H.B.K. Nov. Gen. Am. 6. p. 97. De Cand. Prodr. 3. p. 53. Hook, et Am. 

 supra, p. 291. 



Hab. Between San Bias and Tepic. — Although we believe this to be the J. peploides, H.B.K., we are yet 

 of opinion that it is also the J. Swurtziana, DC. and the J. repens, Linn. ; which latter, though considered 

 by De Candolle to be exclusively a native of the East Indies and adjacent islands, yet we possess specimens 

 from Chile which can in no way be distinguished from it. 



2. J. hirta (Vahl.); frutescens erecta hirsuta, foliis brevissime petiolatis lanceolatis
