ELATINACE.E. 



390. Elatine (Merimea seu Bergia) Texana, Hook. 1c. 

 PL t. 278; Torr. fy Gray, Fl. 1. p. 678. E. (Bergella) 

 Texana, Gray, Gen. 111. 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. 



LYTHRACELE 



f Lythrum alatum var. ovalifolium: 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. alatum, var. pumilum: foliis ellipticis oblongisve, 

 caulibus spithamaeis. Rocks partly covered with water, in 

 Sister Creek. April. — Mixed with this in the distribution 

 are a few fruiting specimens of 



j- L. alatum, var. breviflorum : glabrum, ramosissi- 

 mum ; ramulis angulatis ; foliis linearibus plerisque alternis, 

 floralibus, flores approximates 6-petalos 6-andros subaequanti- 

 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.
