This has hitherto been only seen by Rheede, and known by his figure and 
description ; Lamarck, and following him, Willdenow and De Candolle, have, 
from trusting to the figure, described it with oval flat petals : Rheede, how- 
ever, states the flowers to be the same as in L. Regine, and we suspect the 
flat petal-like bodies to be an exaggerated representation of the calycine seg- 
ments. De Candolle, further, places it among those with the stamens equal, 
and if he be correct there would be no character except the pubescence, 
which is insufficient. of itself, to distinguish it from L. Regine: but Rheede 
says that it differs by having 5 stamens, probably meaning that some are 
longer than the others.

Perhaps this is the same with L. parviflora £: at the same time, there is 
the fragment of a specimen in Dr Wight's collection (Wight ! cat. n. 1037 ) 
with the habit of L. parviflora £, but with the fruit about as large as that of 
L. Regine, which may possibly be the same as Heyne’s plant. 
Subord. 9. CERATOPHYLLERZ. Gray—Calyx 10-12-partite, lobes 
equal. Petals none. Stamens 12-20: anthers ovato-oblong, bilocular, 
bicuspidate, sessile. Ovarium free, ovate, 1-celled: ovule solitary, 
pendulous : style filiform, oblique : stigma simple. Nut |-celled, inde- 
hiscent, terminated by the indurated style. Seed solitary, pendulous. 
Albumen none. Embryo straight : radicle superior ; cotyledons deep- 
ly bipartite, one of the segments smaller, resembling 4 unequal cotyle- 
dons—Aquatic herbs. Leaves verticillate, cut into filiform lobes. 
Flowers uni-sexual. 
. Much as this suborder differs in appearance from the former, we have the autho- 
rity of Richard for uniting them. It must be confessed, however, that their chief 
great resemblance lies in the persistent calyx, free from but surrounding the fruit. -

Character the same as of the suborder. 
956. (1) C. muricatum (Cham. :) fruit elliptical, slightly compressed, fur- 
nished with 3 (or occasionally 4) spines, winged, not gibbous; spines slen- 
der, weak ; wing narrow, regularly many-toothed ; sides of the fruit convex, 
more or less muricated, particularly towards the apex.—Cham. in Linnea, 4. 
p. 504, t. 5. f. 6. c; G. Don, in Mill. dict. 3. p. 706 ; Wight! cat. n. 1038. 
We can see no difference between the Indian specimens and the Egyptian 
ones described by Chamisso, except that the latter appear to have the fruit a 
little more compressed, and its sides less convex. In ours we perceive occa- | 
sionally 4 spines, in which case 2 of them are terminal.

not SUR furnished with 8 een wingless ; spines at first slender and 
Weak, afterwards strong ; sides of the fruit convex. finely tubercled.—Cham.
