 tinct, tardily dehiscent, semielliptical, at length stipitate-. style incurved. — S. Ivira, Sw., 

 partim. — A high tree ; leaves 6-8" long : petiole tumid at the base and at the top ; calyx 

 yellowish, 4'" long; follicle li" long: the carpophore nearly of the same length. — Some of 

 the Dominica specimens have the leaves 3-lobed. — Hab. Jamaica!, Pd. ; Dominica!, Imr., 

 to S. Vincent !, Guild. ; Trinidad !, Pd., in the hills at S. Ann's. 



2*. COLA, Schtt., Endl. 



Calyx rotate, 5-fid. Column depressed, scutelliform, bearing on the margin 10 ovoid an- 

 thers : anther-cells convergent. Carpids 5, many-ovulate : stigmas distinct, sessile. Seeds 

 exalbuminous. — Leaves entire: petiole tumid at both ends ; panicles short, corymbose, axil- 

 lary. 



3*. C. acuminata, P. Br. et Benn. Leaves oblong, pointed at both ends, glabrate ;

 sile. — Beauv. Owar. 1. t. 24. — Sterculia, P. B. — Leaves 6"-8" long; calyx 8'" long, pale-

 in Jamaica !, March ; [introduced from tropical Africa]. 



XXVIII.^BUETTNERIACE^l. 



Calyx valvate. Stamens monadelphous, usually definite, the fertile ones opposite to the 

 petals: anthers 2(-3)-locular, with the pollen smooth. Pistil syncarpous, rarely simple: 

 carpids 5 (-1). — Leaves alternate, stipulate: down usually stellate. 



The Cacao (or oily and nutritious seed of Theobroma) is the most important product of 

 this Order, and a fatty oil prevails also in the embryo of the allied genera. The general 

 properties are the same as in Malvaceee. Thus Guazuma and Waltheria yield a mucilaginous 

 drug, and Ayenia magna is a fibre plant. 



Tribe I. THEOBROMBJE. — Column free from the petals, divided into definite, 

 fertile, and sterile filaments. 



The East Indian Abroma angusta, L., occurs in the S. Vincent collection, but is to be 

 considered only as a cultivated plant. Lunan^remarks that specimens introduced into Ja- 

 maica were in a sickly state. 



1. GUAZUMA, L. 



Calyx 3-(2-4) -partite. Petals 5 : limb cucullate, with a terminal, linear, bifid appen- 

 dage. Column shortly 10-fid : fertile lobes triantheriferous : anthers bilocular. Styles 5, 

 contiguous. Nut tubercled, 5-celled : cells polyspermous. Embryo inflexed, enclosed by a 

 thin endosperm : cotyledons fleshy, plaited. — Trees ; leaves distichous, serrate, usually ob- 

 lique at the base ; coiymbs mostly axillary. 



1. G. tomentosa, Kth. 'Leaves oblong-lanceolate, acuminate, semicordate at the base, 

 scabrous or glabrescent above, pubescent and usually hoary beneath ; nut ovoid-globose, with 

 5 obsolete furrows above. — Cav. Ic. 3. t. 299. — Theobroma Guazuma, L., Sw. Bnbroma, W. 

 Guaz. polybotrya, Cav. G. ulmifolia, Macf. {non Lam.). G. parvifolia, Rich. — A middle- 

 sized tree, usually 15'-20', sometimes 40-50' high : branches with a very tenacious rind, 

 hoary with stellate down ; corymbs nearly twice the length of the petiole ; petals yellow, 1£"' 

 long, with the appendage as long ; nut subdrupaceous, purplish-black, 12"'-8'" long, 9"'-6"' 

 diam. — I cannot confirm the observations published by Richard {Fl. Cub. p. 189) on this and 

 the following species. In both the column bears externally at its base five tufts of hairs, and 

 the longitudinal furrows, the occurence of which in this species he denied, are observable in the
