44. S. Foulteri, Hort. 
Ventral leaf. Nearly circular or slightly oblique, slightly pointed, 
with a faintly spiny margin. Stomata occur along the margin and 
near it; also on the ligular surface. The aligular epidermis consists of 
elongated cells with exceedingly wavy margins and with a few sclerotic 
fibres interspersed. 
Dorsal leaf. Oblong oblique with backwardly directed basal lobe 
and spiny margins. Stomata occur here also on the ligular face near 
the margin. 
Section. As in A. delicaiissima. 
45. S. rubella, Moore. 
The ventral and dorsal leaves are somewhat like those of S. Poulteri 
in form. The margins are faintly spiny. Stomata occur on the 
margin, and along the edge of the ligular face. Warty sclerotic 
cells and stomata are frequent on the aligular surface. 
The dorsal leaf is peltate, the basal lobes joining behind the point 
of insertion of the leaf. There are no stomata on the ligular face, but 
they occur plentifully on the aligular surface. All the cells of the latter 
face are warty. 
Section. As in S. delicatissima. 
46. S. lepidophylla, Spr. 
The ventral and dorsal leaves are both elongated ovate with 
delicate tapering apices and of nearly the same size. The cordate 
bases are fringed with hairs, and the margins are warty and spiny. 
The cells of both ligular and aligular faces of both leaves are strongly 
sclerotic. Stomata occur on both ligular and aligular faces of both 
ventral and dorsal leaves. As already stated (p. 127), Wojinowic and 
Erikson state that although stomata occur on both sides of the ventral 
leaf, they are absent from the aligular face of the dorsal leaf. I have 
examined a large number of dorsal leaves from several plants, 
and never failed to find stomata both on the ligular and aligular 
epidermis. 
Section. The mesophyll consists of reticulate parenchyma only. 
47. S. involvens, Spr. 
The leaves are rhomboid and fringed with spiny processes. The 
apices are long and tapering, like those of A. lepidophylla. The 
epidermis of both sides is like that of the preceding species, and
