OuDER XXXV. CRASSULACE^. 



Succulent or lieshy plants, mostly herbaceous, and not stipulate, with completely 

 symmetrical as well as regular llowers, the sepals, petals, stamens, and pistils all of 

 the same number (3 to 12) and distinct, or the stamens twice as many, and the 

 petals sometimes united into a tube, always free from the pistils, generally slightly 

 perigynous, and instead of a disk a series of hypogynous scales, one behind each 

 carpel ; these become follicles in fruit. Otherwiso'as in SaxiJ'myacea'. The one or 

 two exce[ttions are not ('alifornian. 



An order of ahout 400 Hpocics in httlu over a dozen genera, of tenii>erute and siil)ln>]»ical re- 

 gions, most ahnnihuit in Kuropo and S. Africa, more fully represented in Caiifoiniu tlian in tho 

 Allanlie Stales. All are inert, witii watery juieo ; many are lullivatod for ornament, mostly for 

 tho foUage rather than tlie llowers. 



Si:mi'i;uvivum tkctoiu'm, Linn., the Ilouseleek or Live-forever, of Europe, is often found 

 half wild about old houses : i>arts of the llowers mostly in twelves : leaves oval or ohovate, 

 mueronate, on the llowering stems oblong and elammyiiubescent, as well as the clustered purple 

 or greenish flowers. 



1. Tilleea. Parts of the flower each 3 to 5 ; the stamens only as many. Small annuals, with 



opposite leaves and minute axillary flowers. 



2. Sedum. Parts of the flower each 4 to 7 ; stamens twice as many. Petals distinct. Low 



annual or perennial herbs, with cymose con.spicuous flowers. 



3. Cotyledon. Parts of the flower in lives ; stamens 10. Petals .somewhat united. Stout 



perennial herbs, or fleshy-woody at base, with showy spicate or racemose flowers.

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

 distinct : styles short-subulate : ovules one to many. Seeds longitudinally striate. 

 — Small and slcmler somewhat suc(;ulent glabrous annuals ; leaves opposite, entire ; 

 llowers minute, axillary, mostly while. 



A cosmopolitan genus of about 20 speci.'s. In addition to tho following, there is a single 

 species on the Atlantic coast and another in Texas. 



-.v Flowers clustered: petals acuminate: hypogynous scales viiniite or none: carpels 

 1 - 2-seeded. — TlLL/EA proper. 



1. T. minima, TNIiers. Dill'usely branched, 1 to 3 inches high, erect or ascend- 

 ing : leaves ovate to oblong, connate at base, acute, about a line long : llowers in 

 short leafy axillary panicles, nearly sessile or on pedicels a line or two long : sepals 



4. scarcely half a line long, oblong-ovate, acute, a little exceeding tho linear lanceo- 

 late acuminate; petals: carpels not longer, acute : seeds usually solitary. — Torr. & 

 Gray, Fl. i. 557. 



Var. subsimplex, Watson. Ihunchlets more elongated, mostly from the base : 

 pedicels usually shorter. — 2'. leptopetala, Denth. PI. Ilartw. 310. 



On sandy soils, in the rainy season, often abundant, from Sonoma Co. to San Diego ; Guada-
