424 MEXICO— SUPPLEMENT. [Cucurbitacece. 



Hab. Realejo. — Stems stout and woody, almost terete, the branches obtusely 4-sided, clothed, as are the 

 leaves, calyx and ovary, with erect, close-pressed, pale, rusty coloured shining setae, giving a silky appearance 

 to the eye. Leaves 2 inches or 2| inches long, on rather short petioles, oblong-lanceolate, entire, acute, 

 marked with from 3-5 strong, parallel nerves. Flowers corymbose on small terminal branches, which collec- 

 tively form a corymbose panicle. Flowers crowded, and rather small. Calyx 5-cleft ; the tube ovate, marked 

 with ten slightly elevated lines, and, as well as the Ianceolato-subulate erect lobes, clothed with appressed, 

 rigid hairs; the lobes are eventually deciduous. Petals 5, oblongo-obovate, ciliated. Stamens 10, 4 large 

 and 4 small ; but the anthers all uniform, linear, opening by a single conspicuous pore at the extremity, and 

 furnished at the base with a projecting horizontal tubercle. Ovary ovate, the lower half adherent with the 

 base of the calyx, the upper half free, and covered with erect, close-pressed bristles ; style clavate, glabrous. 

 The fruit is a capsule included within the truncated calyx. 



Ord. XIX. CUCURBlTACEvE. Juss. 



1. Bryonia attenuata; monoica, caule profunde striato* glabro, foliis late ovatis oblon- 

 gisve integris vel profunde trilobis basi cuneatis utrinque scabris subtus pubescentibus 

 sinubus obtusis lobis cuneato-oblongis obtuse serratis serraturis mucronatis, floribus 

 racemosis, pedicellis inferioribus subfasciculatis — Anguria? dubia, Hook, et Am. supra, 

 p. 292. 



Hab. Acapulco. — From the former Mexican collection we attempted to draw up a character of this plant 

 with the aid of only very imperfect specimens. Those from Dr Sinclair have both flower and fruit. The 

 male flowers are green and about as large as those of our Bryonia diocia. Filaments 3. Anthers combined 

 and flexuose. The berries are rather larger than those of the common Bryony, filled with white mealy pulp, 

 and flat seeds. 



1. Momordica? quinquefida, Hook, et Am. supra, p. 292. 



Hab. Acapulco. — The fruit here is more perfect than in our former specimens, and is ovoid.
