said that the stems of Nymphsea alba, are better than oak galls for dying 
gray ; they have also been long employed advantageously for tanning leather ; 
and a tolerable sort of beer has been prepared from them. Fee, 1, 412.

Sub-Order. HYDROPELTIDE^. 
CABOMBEiE, Rich. Anal. Fr. (1808.) — Podophyllace^, § Hydropeltideae, DC. 
Syst. 2. 36. (1821); Prodr. 1. 112. (1824). 
Essential Character. — Sepals 3 or 4, coloured inside. Petals 3 or 4, alternate with 
the sepals. Stamens definite or indefinite, hypogynous, arising from an obscure torus ; 
anthers linear, turned inwards, continuous with the filament. Ovaries 2 or more, termi- 
nated by a short style. Fruit indehiscent, tipped by the hardened style. Seeds definite, 
pendulous ; embryo fungilliform, seated at the base of firm, somewhat fleshy albume7i . — 
Aquatic plants, with floating leaves. Flowers axillary, solitary, yellow or purple. 
Affinities. These appear to be in reality nothing more than Nymphsea- 
ceous plants with definite seeds and distinct carpels. From Podophyllese, to 
which they are united by De Candolle, they difibr in their floating habit, 
definite seeds, and numerous ovaries. According to Richard, Cabomba is a 
monocotyledon : Hydropeltis is clearly related closely to Caltha.

Order IV. NELUMBIACE.^. 
NYMPH.®ACEiE, § Nelumboneae, DC. Syst. 2. 43. (1821) ; Prodr. 1. 113. (1824) — Nelum- 
BONE^, Martius Conspectus. No. 187. (183.5.) 
Essential Character. — Sepals 4 or 5. Petals numerous, oblong, in many rows, 
arising from without the base of the disk. Stamens numerous, arising from within the 
petals, in several rows ; filaments petaloid ; anthers adnate, bursting inwards by a double 
longitudinal cleft. Disk fleshy, elevated, excessively enlarged, enclosing in hollows of its 
substance the ovaries, which are numerous, separate, monospermous, with a simple style 
and stigma. Nuts numerous, half buried in the hollows of the disk, in which they are, 
finally, loose. Seeds solitary, or rarely 2 ; albumen none ; embryo large, with two fleshy 
cotyledons and a highly developed plumule, enclosed in its proper membrane. — Herbs, with 
peltate, fleshy, floating leaves arising from a prostrate trunk, growing in quiet waters. 
Affinities. The relationship of this order to Nymphaeacese is so obvi- 
ous, that no one ever thinks of disjoining them. And yet its numerous dis- 
tinct ovaries are quite diflJerent from the fruit of Nymphaeaceae, and the seeds 
have no albumen. This latter circumstance forms the only important excep- 
tion to the character of the Albuminous group. 
Geography. Natives of stagnant or quiet waters in the temperate and 
tropical regions of the northern hemisphere, both in the Old and the New
