those of the stems 2-3 inches long; those of the stolons spatulate. Capsules
a little longer than broad, 2-3 lines in diameter, with a broad and flat
slightly 4-lobed stylopodium. Seeds oblong-oval, smooth and shining.
8. L. alata (Ell.) : glabrous, stem erect, more or less winged by the decurrent
base of the lanceolate leaves;, flowers axillary, solitary, sessile,
apetalous ; bracteoles lanceolate, coherent with the base of the ovary; lobes

9. L . sphrerocarpa (E ll.): minutely puberulent or nearly glabrous ; stem
erect, slightly angled; leaves lanceolate, acute, attenuate at the base; flowers
axillary, mostly solitary, subsessile, commonly apetalous; bracteoles

the lower portion, when growing in water, subject to a peculiar disease of

when present, small and greenish. Capsules 1-2 lines long. Seeds

stolons from the base, slightly angled, much branched ; leaves narrowly lanceolate,
acute, attenuate at the base; flowers axillary, sessile, solitary, or

ovary; lobes of the calyx half the length of the capsule, triangular; capsules
