56 CARYOPHYLLE^I. 



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

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

 bifid, included ; stamens usually 3 ; capsule equalling the calyx : seeds 8-2, granulose. — 

 Lam. III. t. 51 : Holost.f. 2. — Holosteum, L. — Intermediate forms with D. diandra, Macf. 

 (Holosteum, Sw.f), are of common occurrence ; the original Swartzian type however may be 

 regarded as a special variety. 



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



0. diandra. Leaves minute (2'" diam.) ; sepals puberulous (half the size of o) ; stamens 

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

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



6. CYPSELEA, Turp. 



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

 Capsule circumscissile. — Leaves opposite, and partly alternate, dotted. 



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

 third one is opposite a sepal, that the character of the Portulacece, as proposed by Fenzl, 

 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 Portulacea. 



6. C. humifusa, Turp. — Turp. in Ann. Mus. 7. t. 12. /I 5. — A small, annual, decum- 

 bent, branched, glabrous'herb ; leaves oval, petioled, l^'"-2"' long : stipules laciniate; flowers 

 small, greenish, axillary among the leaves of reduced branches. — Hab. Caribbean*lslands, in 

 dry swamps ; [Haiti to Guadeloupe !]. 



Tribe IV. MOLLTJGINEJE. — Sepals united below. Petals \utually wanting. Capsule 

 plurilocular. — Leaves rosulate : stipules fugacious or obsolete. 



7. MOLLUGO, L. 



Calyx 5-partite, coloured inside. Petals 0. Stamens 5-3 (-10), hypogynous. Styles 3. 

 Capsule trilocular, loculicidal, trivalved, many-seeded. 



7. M. verticillata, L. Annual, glabrous, branched; leaves spathulate or oblanceolate- 

 linear, rosular at each node; pedicels 1 -flowered, umbellate; stamens 3; seeds smooth, 

 3-5-costate. — Gray, Gen. Bor. Amer. t. 101. — Hab. Jamaica!, in barren situations; 

 [United States ! to Brazil !, and Galapagos Islands !]. 



8. M. nudicaulis, Lam. Annual, glabrous, leafless above the base ; leaves spathulate- 

 oblong, rosular at the lowest node ; flowers arranged in corymbiform panicles : pedicels 

 filiform; stamens 5; seeds minutely granulose. — SI. t. 129./. 2; Besc. Fl. 5. t. 317. — M. 

 bellidifolia, Ser. Pharnaceum spathulatum, Sw. — Hab. Jamaica, in dry^situations Sw. ; 

 S. Lucia ! ; [Cuba ! to Guiana !, Nubia !, East Indies !]. 



Tribe V. P OBTUL ACL 'M— Sepals 2, distinct, or combined at the base.— Leaves somewhat 

 fleshy, devoid of scarious stipules. 



8. TALINUM, Ad. 



Sepals 2, distinct. Petals 5, hypogynous, delicate. Stamens 10-30, hypogynous. Style 

 trifid. Capsule unilocular, trivalved, many-seeded. 



9. T. triangulare, JF. Suffruticose ; leaves alternate, obovate-lanceolate, tapering 

 towards the subsessile base ; flowers red (or white), arranged in terminal, corymbiferous 

 cymes : pedicels triquetrous ; stigmas divergent. — Jacq. Amer. Picl. t. 135 : the flowers 

 yellow by some mistake. Jacq. Obs. 1. t. 23. Jacq. Findob. 3. t. 52 : a branched form. 

 — Portulaca, Jacq. P. crassicaulis, Jacq. Tal. crassifolium, JF. T. fruticosum, IF. — A 

 succulent half-shrub ; stem about 2' high, either simple and terminated with a few-flowered 

 cyme (the original T. triangular e), or branched and higher (T. crassifolium): the leaves 

 usually broader in the branched form, often emarginate and mucronate ; sepals somewhat 

 persistent, ovate or ovate-lanceolate, half the length of the corolla ; petals large, rounded (6'" 

 diam.); stamens about 30; seeds minutely granulose.— Hab. Jamaica!, Bist., on dry, sandy 

 seashores; [Guadeloupe !, Brazil!, Peru!].
