WIIIPPLKA. 



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 th3 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 placentae projecting into the cells, many- 

 seeded. Seeds pendulous and densely imbricated downward on 

 the thickened placentae, with a loose coat, usually prolonged at 

 both ends or fimbriate at the hilum. 



P. Lewlsii 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-LO lines long; 

 filaments unequal the longer ones about half as long as the petals; styles 

 about equalling the shorter stamens, deeply 2-4-cleft. Common in open 

 woods and rocky hillsides, Brit. Columbia to California. 



2 WHIPPLE i Terr. Pac. R. Rep. iv, 90, t. 7. 



Small diffuse shrubs with opposite simple leaves and small 

 white flowers in cymous clusters on terminal naked peduncle?. 

 Calyx 5-cleft, the tube coherent with the lower part of the ovary, 

 the lobes thin and petal-like. Petals 5. Stamens 10, rarely rdore 

 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. moftesta 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 campanulate, the white oblong lobes longer than the tube; 

 petals white, with a lanceolate blade and broad claw, longer than the 

 calyx-lobes : capsule globose : styles at length deciduous: seeds oblong. In 

 open woods, from near the Columbia river to California. 



Order XXXII. RIBESACE^. 



Spiny or smooth shrubs with alternate oft«n fasci(iled pal- 

 mately veined leaves without stipules, and few to numerous, - 

 mostly perfect, flowers in racemes, either produced from the 

 bud with the leaves and terminating the very short axillary, s 

 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, niarcescent, imbricate in 

 the bud. Petals distinct, equal in number to the segments of 

 the calyx and alternate with them, iuserte I in the thtoat of the 

 calyx. Stamens as many as petals and inserted alternately 

 with them: anthers introrse. Ovary 1-celle I with two parietal 

 placentffi: ovules numerous, or sometimes few; styles 2, larely
