56 CARYOPHYLLE^. 



5. D. cordata, W. Annual, glabrous; leaves orbiculate, subcordate at the base; pedi- 

 , eels filiform, arranged in lateral cymes ; sepals ovate-lanceolate, acuminate ; petals deeply 



"^bifid, included ; stamens usually 3 ; capsule equalling the calyx r seeds 8-2, grauulose. — 

 Lam. m. i. 51 : Eolast.f. 2.— Holosteum, i.— Intermediate forms with D. diandra, Maof. 

 (Holosteum, Sio.!), are of common occurrence ; the original Swartziau type however may be 

 regarded as a special variety. 



a. Leaves 4"'-6"' diam.; sepals glabrous (IV" long). 



3. dymdra. Leaves minute (2"'-diam.); sepals pubernlous (half the size of a); stamens 

 2 ; seeds less numerous. — Hab. Jamaica !, Maef., March, to Trinidad !, Sieb., Lockh., Cr., 

 common ; [Cuba ! and Mexico 1 to Brazil I and Peru 1 ; East Indies!]. 



6. CYPSELEA, Turp. 



Calyx 5-partite. Petals 0. Stamens 3-1, alternate with the calyx-segments. Sti/les 2. 

 Capsule circumscissile. — Leaves Ofposite, and partly aliernate, dotted. 



Asa Gray having shown by the position of the stamens in Mollugo vertidllata, where the 

 third one is opposite a sepal, that the character of the Portvlaceee, as proposed by Eenzl, 

 cannot be relied upon [Gen., Bor. Amer. 2. p. 10), I consider Cypselea better placed among 

 the Paronychiece, the scarious stipules of which it possesses, its habit agreeing much more 

 with Herniaria than with any true Portulaeea.

 dry swamps ; [Haiti to Guadeloupe !].
