170 ORPINE FAMILY. 



H- -i- Leaves sprinkled with resinous dots ; flowers larger, with oblong- 

 bell-shaped calyx berries larger, black, aromatic and spicy, glandular- 

 dotted. 



R. fl6ridum, L'Her. WILD BLACK C. Woods N. ; leaves slightly 

 heart-shaped, sharply 3-5-lobed and doubly serrate ; racemes drooping, 

 downy, bearing many whitish flowers, with conspicuous bracts longer 

 than the pedicels. 



R. mgrum, Linn. GARDEN BLACK C. Cult, from Eu. ; much like 

 the preceding, but has greener and fewer flowers in the raceme, minute 

 bracts, and a shorter calyx. 



* * Flowers highly colored (red or yellow}, much larger. 



R. sangufneum, Pursh. RED-FLOWERED C. From Ore. and Cal. ; 

 glandular and somewhat clammy, with 3-5-lobed leaves whitish-downy 

 beneath, nodding racemes of rose-red flowers, the calyx tube oblong- 

 bell-shaped, the berries glandular and insipid. 



R. GORDONIANUM is supposed to be a hybrid between this and the 

 next. 



R. aureum, Pursh. GOLDEN, BUFFALO, MISSOURI or CRANDALL CUR- 

 RANT. From Mo. to Ore. ; abundantly cult, for its spicy-scented bright- 

 yellow flowers in early spring ; smooth, with rounded 3-lobed and 

 cut-toothed leaves (which are rolled up in the bud), short racemes with 

 leafy bracts, and tube of the yellow calyx very much longer than the 

 spreading lobes ; the berries blackish, usually insipid. 



XL. CRASSULACE^E, OKPIKE FAMILY. 



Succulent plants, differing from the Saxifrage Family mainly 

 in the complete symmetry of the flowers, the sepals, petals, 

 stamens, and pistils equal in number, or the stamens of just 

 double the number; the pistils all separate and forming as 

 many (mostly many-seeded) little pods, except in Penthormn, 

 where they are united together. (Lessons, p. 81, Figs. 222- 

 225.) Penthorum, which is not succulent, is intermediate 

 between this family and the foregoing. Several are somewhat 

 monopetalous. 



1. Leaves not at all fleshy, but thin and membranaceous ; the 5 ovaries united into 

 one 5-horned ^-celled pod ; no scales behind the ovaries. 



1. PENTHORUM. Sepals 5. Petals 5, small, or usually none. Stamens 10. Pod open- 



ing by the falling away of thp 5 beaks, many-seeded. Karely the parts are in sixes or 

 sevens. 



2. Leaves thickened and succulent; ovaries separate, a minute scale behind each. 

 * Petals separate; sepals nearly so or united at the base. 



2. SEMPERVIVJJM. Sepals, narrow petals, and pistils 6-12 or even more, and stamens 



twice as many. Plants usually multiplying by leafy offsets, on which the leaves are 



crowded in close tufts like rosettes. 

 3.. SEDUM. Sepals, narrow petals, and pistils 4 or 5; the stamens twice as many, the 



alternate ones commonly adhering to the base of each petal. 

 4. CRASSULA. Sepals or lobes of the calyx, petals, stamens, and many-seeded pistils 5. 



Perennial herbs or fleshy-shrubby plants, with flowers in cymes or clusters.
