156 THALAMIFLOR*:. 



traversed on the inner surface with a delicate ridge. Hy- 

 pogynous glandules connected at the base, linear, slightly in- 

 curved. Stamens 8 : filaments of nearly the same length as 

 the petals, monadelphous at the base where they adhere to the 

 hypogynous disk: anthers reniform, curved. Rudiments of 

 the pistil consisting of a small villous ovary and short style, 

 concealed in the centre of the groupe of filaments. <j> Flowers : 

 Calyx and corolla the same ; but the hypogynous glandules 

 shorter and broader than in the barren flowers. Stamens half the 

 length of the petals, (of nearly the same length as the ovary), 

 free at the base : anthers oblong, cordate at the base, apparently 

 destitute of pollen. Ovary oval, 6-angular, pubescent : styles 

 3, erect rather longer than the petals, cohering towards the 

 ovary : stigmata obtuse. Carpels 3, connate to form a capsule 

 2 inches in length, of a somewhat pyriform shape, inflated, acu- 

 minate, tomentulose : seeds globose, shining, black with a white 

 heart-shaped hilum. 



II. SERJANIA. 



Calyx 5-sepalled. Petals 4, appendiculated on the 

 inner surface, with the place for a fifth petal vacant. 

 Stamens 8. Carpels 3 (samaroid) longitudinally con- 

 nected, 1 -seeded at the apex, dilated beneath into a 

 membranaceous wing. De Cand. 



Scandent shrubs, with leaves ternato-compound. 



1. Serjania equestris. Mountain Supple-jack. 



Leaves biternate, leaflets ovate retuse apiculated 

 attenuated at the base crenato-serrated towards the 

 apex glabrous with the upper surface shining, petioles 

 naked, wings of the carpels oblong and rounded at 

 the angles. 



HAB. Common. 



FL. October. 



Stem shrubby, climbing to a considerable height on neigh- 

 bouring shrubs and trees: branches long," virgate, 3-gonal, 

 somewhat sulcated and puberulous toward their extremities. 

 Leaves alternate, bi-ternate : leaflets about 2 inches long, 

 ovate, retuse, apiculated, attenuated (the middle leaflet wedge- 

 shaped) at the base, bluntly serrated for the terminal half, 

 nerved, shining on the upper surface, glabrous except a minute 

 villous tuft in the axils of the nerves beneath, thin, membrana- 

 ceous : common and partial petioles naked, 3-gonal, bisulcated 

 above. Tendrils axillary, bifid. Racemes axillary and termi- 

 nal, solitary, longer than the leaf, divaricating, compound,
