Pl. t. 278; Torr. & Gray, Fl. 1. p. 678. E. (Bergella) 
Texana, Gray, Gen. Ill. 1. p. 218. t. 96. In slow flowing 
rivulets, New Braunfels. August. — This is a pentamerous 
and decandrous or sometimes pentandrous Elatine, with the 
aspect of Bergia, for which, in the work above cited, I have 
indicated a distinct section. 
LYTHRACEZ: 
+ Lyrarum aLatum var. ovaLiFotium: humile; foliis sub- 
orbiculatis et ovalibus, floralibus oblongis calyce brevioribus. 
L. ovalifolium, Englm. Mss. Springs of the Pierdenales, on 
rocks covered by water. October. — Stems a foot high, from 
long and creeping stolons. Leaves one third of an inch long. 
This evidently runs into the next. 
(609.) L. auatum, var. pumiLum: foliis ellipticis oblongisve, 
caulibus spithameis. Rocks partly covered with water, in 
Sister Creek. April. — Mixed with this in the distribution 
are a few fruiting specimens.of 
+L. auarum, var. BREvIFLoRUM: glabrum, ramosissi- 
mum; ramulis angulatis ; foliis linearibus plerisque alternis, 
floralibus, flores approximatos 6-petalos 6-andros subeequanti- 
bus; calyce fructifero campanulato seu brevissime clavato 
subpedicellato; stylo incluso vel breviter exserto. — Damp 
rocks on the Guadaloupe, near running water. ‘The speci- 
men is the branching summit of an apparently rather tall 
stem, which has lost its lower leaves. ‘The floral leaves are 
only from one to three lines long; the flowers are so approxi- 
mated as at length to form a virgate spike. The calyx even 
in fruit is barely a line and a half in length. Petals purple, 
small, those of the later flowers minute or wanting. The 
style is shorter than the petals, often included, or barely equal- 
ling the stamens; but the specimen, perhaps, belongs_to a 
stamineal form. Vide Pl. Lindh. p. 8. No. 52. CS
