MR. G. BENTHAM ON THE GENERA SWEETIA AND GLYCINE. 261 
at first sight is characteristic of Cæsalpinieæ, occurs also in Barklya, 
Cadia, and several other Sophoree ; the flat coriaceous indehiscent 
pod with thin edges occurs in Dalbergiex and Sophorex, as well 
as in Cæsalpinieæ. 
I have now only to subjoin short diagnoses of the several spe- 
cies contained in the Kew herbaria. 
SWEETIA, Sprengel. 
CHAR. Gen.—Calycis turbinato-campanulati dentes vel lobi valvati aut 
vix imbricati. Petala 5, subsimilia, erecto-patentia, imbricata, summo 
exteriore. Stamina 10, libera, parum inzequalia, exserta; antherc uni- 
formes. Ovarium sessile vel breviter stipitatum, 2-4-ovulatum ; stylus 
filiformis, stigmate parvo vel truncato terminali. Legumen plano-com- 
pressum, coriaceum vel membranaceum, indehiscens. Semina plano- 
compressa, exalbuminosa ; radicula nunc brevis et recta nunc longior et 
incurva velinflexa.—Arbores. Folia pinnata, foliolis coriaceis ; stipulze 
parve vel inconspicuz. Flores parvuli, racemosi, racemis ad apices 
ramorum paniculatis. Bractee et bracteole anguste vel minutze, sæpius 
caducissimz. 
Sect. I. Acosmium. Calycis dentes seu lobi tubo breviores. Embryonis 
radieula incurva v. inflexa. 
l. S. FRUTICOSA, Spreng. Syst. ii. 213. Foliolis (multijugis?) parvis 
oblongis nitidis venosis, racemis gracilibus puberulis, calyce brevis- 
sime dentato, petalis calyce duplo longioribus, vexillo latissimo.— 
Acosmium lentiscifolium, Vog. in Linnea, xi. 395, non Schott. 
Hab. Rio Janeiro, Sello. 
The specimens are all in the same state as those seen by Vogel, 
in flower only, without leaves, except a few loose fragments, show- 
ing leaflets of 3 to 4 lines; the petals are much shorter and broader 
than in S. lentiscifolia. 
2. S. LENTISCIFOLIA, Spreng. Syst. Cur. Post. 406.  Foliolis multijugis 
oblongis nitidis venosis, racemis gracilibus pubescentibus, calycis den- 
tibus tubo vix brevioribus, petalis calyce subtriplo longioribus, vexillo 
paulo latiore.—Acosmium lentiscifolium, Schott, in Spreng. l. > 
Foliola 1-1 poll. longa, basi oblique angustata. Petala longe ungui- 
culata. Filamenta gracilia. Legumen tenue, glabrum, nunc pollicare 
l-spermum, nunc 2-pollicare 2-spermum, inter semina valde con- 
tractum (ovulo tertio intermedio abortiente?). Semina plana, oblonga, 
sub apice lateraliter affixa; cotyledones oblonge ; radicula longiuscula 
basi inflexa, cæterum recta. 
Hab. Province of Rio Janeiro, Schott. 
Sect. II. Mesitis, Vog. Calycis lobi tubo longiores. Embryonis radi- 
cula incurva accumbens. 
.9. S. Bısuca. Foliolis 4-8 ovali-oblongis reticulatis subtus glaucis, 
x2
