united at base. Carpels distinct, few- to many-seeded. (Probably Tillaea, +-L. aster—=a 
contemptuous diminutive suffix; from their lack of beauty.) 
A. Leaves obtuse, 46 mm. long; flowers sessile or nearly so, the pedicels elongating 
but little in fruit. E. (Tillaea angustifolia.) 
T.. aquaticum Brit. 
AA. Leaves acute, 2—4 mm. long; flowers with pedicels at least equal to the calyx, 
eventually as long as the leaves or longer. E. 
T. drummondii Brit. 
DUDLEYA 
Perennial. Basal leaves flat, linear to ovate; stem-leaves usually much shorter and 
relatively wider, sessile or clasping. Flowers yellow or orange or red or rarely white, 
mostly in panicles. Calyx conspicuous, 5-lobed; lobes linear-lanceolate to ovate. Petals 
united below middle, erect or somewhat spreading at tip. Stamens 10, distinct. Car- ; 
pels erect, many-seeded. (Honor of W. R. Dudley, an American botanist.)  U. r, 
(Cotvledon farinosa.) D. farinosa Brit. 
GORMANIA 
Low, Sedum-like, perennial by horizontal rootstocks. Basal leaves spatulate to obo- 
vate or nearly orbicular, stem-leaves similar but smaller. Flowers cymose or thyrsoid, yel- 
low to red. Calyx mostly deeply 5-lobed. Petals united below middle, somewhat spread- 
ing above. Stamens 10, on the corolla. _ Carpels many-seeded, united below, erect or 
nearly so even in fruit. (Honor of M. W. Gorman, an American botanist. ) 
A. Corolla red or pink. U. G. laxa Brit: 
AA. Corolla yellow. 
B. Corolla-segments long-acuminate, much exceeding the filaments; pedicels mostly 
shorter than the calyx. W.C.E. (Sedum oreganum. ) 
G. oregana Brit. 
BB. Corolla-segments acute to acuminate, little longer than the filaments; pedicels 
mostly longer than the calyx. 
C. Leaves spatulate. E. (Cotyledon oregonensis. ) 
G. watsoni Brit. 
CC. Leaves orbicular. E. (Sedum debile.) 
G. debilis Brit. 
SEDUM STONE-CROP 
Annual or perennial, mostly glabrous; stem erect or decumbent. Leaves alternate 
in most, often imbricate, entire or dentate. Flowers perfect or dioicous, in racemes or 
cymes; clusters often |-sided. Calyx 4—5-lobed or -parted. Petals distinct or some “ 
of them united at the very base, in ours yellow or purple. Stamens 8 or 10, perigynous, 
the alternate ones usually attached to the petals. Carpels-distinct or united at the very 
base, few- to many-seeded. (L. sedere=to sit; because the basal tuft of leaves is often 
flat on the rocks.) 
A. Leaves spatulate or obovate, widest above their middle, flat. 
B. Flowers purple, dioicous; racemes not I-sided. C. E. (Rhodiola integrifolia; 
S. rhodiola.) S. integrifolium Nels. 
BB. Flowers yellow, perfect; racemes 1|-sided. 
C.  Follicles erect or nearly so; basal leaves spatulate, with line of pits under- 
neath near margin. W.E.  §. spathulifolium Hook.
