206 RIBESACE#. PHILLADELPHUS. 
WHIPPLEA, 
the ovary nearly or quite to the summit, the limb 4—5-parted, 
valvate in the bud, persistent. Petals 4-5, large, convolute in 
the bud. Stamens 20-40, shorter than th: petals. Styles 3-5, 
usually 4, united sometimes nearly to the summit: stigmas ob- 
long or linear. Capsule mostly 4-celled. free at the summit; 4- 
valved, loculicidal, the placente projecting into the cells, many- 
seeded. Seeds pendulous and densely imbricated downward on 
the thickened placente, with a loose coat, usually prolonged at 
both ends or fimbriate at the hilum. 
P. Lewisii Pursh Fl. 329. Shrub 3-12 feet high: leaves broadly lance- 
olate, entire or serrate, acute, more or less pubescent both sides: flowers 
in small cymes at the ends of the branchlets;: lobes of the calyx acute, 
twice the length of the tube: petals white, oblong-ovate, 6-10 lines long; 
filaments unequal the longer ones about half as long as the petals; styles 
about equalling the shorter stamens, deeply 2-4-cleit. Common in open 
woods and rocky hillsides, Brit. Columbia to California. 
‘2 WHIPPLEA Torr. Pac. R. Rep. iv, 90, t. 7. 
Small diffuse shrubs with opposite simple leaves and small 
white flowers in cymous clusters on terminal naked peduncles. 
Calyx 5-cleft, the tube coherent with the lower part of the ovary, 
the lobes thin and petal-like. Petals. 5. Stamens 10, rarely more 
or less; anthers short, 2-celled. Ovary 3—-5-celled with a single 
suspended ovule in each cell; styles distinct; stigmas introrse. 
Capsule septicidally dehiscent into 3-5 cartilaginous 1-seeded 
closed valves which open down the ventral suture only. Seeds 
oblong with a closed coat. 
W. modesta Torr. 1.c. Stems slender, spreading or trailing, rooting 
at the nodes, 1-2 feet long or more: leaves ovate or oval, obtusely few- 
toothed or entire, somewhat 3-ribbed, 8-12 lines long, tapering below to a 
short petiole, acute or acutish, pubescent both sides: flowers white, few, in 
in a close cyme at the end of a rather long slender peduncle hardly 2 lines 
broad ; calyx gee vyebin, the white oblong lobes longer than the tube; 
petals white, with a lanceolate blade and broad claw, longer than the 
calyx-lobes: capsule globose: stvles at length deciduous: seeds oblong. In 
open woods, from near the Columbia river to California. 
Order XXXII. RIBESACE/R. 
Spiny or smooth shrubs with alternate often fascicled pal- 
mately veined leaves without stipules, and few to numerous, 
mostly perfect, ~flowers in racemes. either prodyeed from the 
bud with the leaves and terminating the very short axillary 
branchlets, or sometimes leafless buds. Calyx campanulate or 
tubular, colored, the tube adherent to the ovary, the limb 4-5- 
cleft, with mostly equal segments, marcescent, imbricate in 
the bud. Petals distinct, equal in number to the segments of 
the calyx and alternate with them, inserte | in the throat of the 
calyx. Stamens as manv as )etals and inserted alternately 
with them: anthers introrse. Ovary 1-celle with two parietal 
placentz: ovules numerous, or sometimes few; styles 2, rarely
