dark green, very smooth and shining above, rounded and 3-lobed; lobes 

 short, crenately-toothed: peduncles pendulous, 2— 5-flowered: fl. bright 

 red, often 2 in. long from the base of the ovary to the tips of the long- 

 exserted .stamens; calyx cylindraceous, the 4 (rarely 5) lobes erect;

Obdbb xxxix. CRASSULACE/E. 



Succulent herbs with exstipulate leaves. Flowers symmetrical, 

 cymosely arranged. Sepals 3 — 20, more or less united at base. Petals 

 as many, inserted in the bottom of the calyx, distinct or cohering below 

 fco form a gamopetalous corolla. Stamens as many or twice as many as 

 the petals, when of the same number alternate with them; filaments 

 subulate. Ovaries as many as the petals, opposite to them, each with 

 or without a hypogynous scale at base. Fruit follicular. Seeds attached 

 to the margins of the suture, small, albuminous. 



1. TILLJilA, Micheli. Small and slender fleshy glabrous annuals. 

 Leaves opposite, entire. Flowers minute, axillary, white or pinkish. 

 Sepals and petals 3—5, distinct or united at base. Stamens as many. 

 Carpels distinct; styles short-subulate. Follicles 1 — several-seeded. 

 Seeds striate lengthwise.

1. T. minima, Meiers. Simple or with few or many ascending 

 branches, 1 — 3 in. high: herbage very light green when young, in age 

 reddish: internodes short: leaves ovate or oblong, obtuse, 1 line long, 

 connate: fl. in short axillary panicles, mostly subsessile, occasionally 

 some with long pedicels: sepals 4, % line long, acute, nearly or quite

2. T. Drummondii, Torr. & Gray. Stems very slender, dicholomous, 

 diffuse, rooting at some of the lower nodes, 1 in. long or more: leaves 

 oblong-linear, slightly connate: pedicels at length equalling or exceeding 

 the leaves: petals red, fully equalling the obtuse carpels, and twice or 

 thrice the length ot the calyx-lobes. — Common in moist low places in 

 wheat fields near Suisun. May. 



3. T. Bolauderi, Greene. Stems sloutish, simple, 2—5 in. long, the
