lateral petals is the same in both; the germen of V. odorata 
is hairy, in the other species almost smooth. 
60. Viola palustris.—May, 182.—Stipules fringed, not 
serrated, (I think,) but nearly entire, as stated in Eng. Fl. 
Lateral petals with a purple central line, not hairy; the 
petals, however, are slightly hairy on one side, near the base. 
61. Erythrza pulchella.—Anglesea, July 15, 1828.—An- 
thers very short. Segments of the calyx strongly keeled, very 
deep in proportion to the tube.. Herbage very smooth. 
62, Samolus Valerandi.—July, 1828.— Filaments very near 
the base of the tube of the corolla. 
63. Rhamnus catharticus.—June, 1827.—In the barren 
flower, the tube of the calyx is campanulate, segments ovate, 
3-ribbed. Petals (4) oblong-ovate, inserted just below 
the mouth of the calyx, alternate with its segments. Stamens 
inserted just below the petals: there is an abortive germen 
visible. In the fertile flower, the petals are linear, incurved 
above. Stamens abortive. Styles 4, united half-way up, 
spreading. Stigmas small, slightly decurrent along the inner 
edge of the styles: germen superior.—October, 1826.—The 
Seeds are ovate, acute at the lower extremity, rounded at the 
back, with two flat sides, forming the internal angle. Embryo 
with kidney-shaped cotyledons laterally bent, surrounded by 
the albumen. 1 thought I saw two skins, within the hard 
external one, and the latter seems to split at the internal 
angle. Serratures of the leaf very close and regular, rounded 
- and glandular; ribs of the leaf aene ume qe eta 
furrowed or depressed on the other. d 
64. Rhamnus Zrangula.—June, 1827. 2: Pioweretals and | 
calyx generally downy, also the ribs on the back of the leaf. 
Anthers white. Style very short.
