350 SAXIFRAGACEAE 



and a leafy axial stem terminated by a loose panicle of relatively large purplish flowers. 

 Rootstocks short and bulbiferous. Leaves reniform, most of the cauline with conspicuous 

 stipules. Panicle with more or less leafy bracts. Hypanthium deeply urceolate-campanu- 

 late, free from the ovary. Sepals 5, long-attenuate. Petals 5, purplish, subulate-lanceolate, 

 long-attenuate, persistent, sessile, alternating with the sepals. Stamens 5, opposite the 

 sepals; filaments subulate to filiform; anthers 2-lobed. Carpels 2, attenuated above, united 

 at the base for one-third to one-fourth their lengths ; ovary completely 2-celled ; stigmas 

 small, capitate; placentae axile, many-ovuled; seeds pendulous. [Dedicated to Dr. Henry 

 N. Bolander, one of the botanists of the California Geological Survey.] 



A genus confined to the Pacific States, containing the two following species. Type species, Bolandra cali- 

 fornica A. Gray. 



Lobes and teeth of the leaves rounded, mucronulate; sepals 3-4 mm. long; carpels connate a third their lengths. 



1. is. calif ornica. 



Lobes and teeth of the leaves triangular, acute; sepals 6-10 mm. long; carpels connate at most a fourth their 

 lengths. 2 - B - oregana.

Stems 1-3 dm. high, very slender, glabrous below, glandular-puberulent above. Basal and 

 lower cauline leaves petioled ; petioles 2-10 cm. long ; blades reniform. thin, glabrous, more or 

 less deeply 5-7-lobed ; lobes rounded-ovate, their teeth crenate-serrate and mucronulate ; upper 

 cauline leaves sessile, ovate-toothed ; the middle ones often auricled by the union of the stipules 

 and the blades ; hypanthium proper greenish or purplish, about 5 mm. long ; sepals lance-subu- 

 late, 3^ mm. long, often acuminate ; petals subulate, more or less attenuate, greenish, the edges 

 and' tips purplish, slightly longer than the sepals; filaments narrowly subulate. 



In moist places or on wet rocks, mostly confined to the Canadian Zone; Yosemite and Lake Tahoe region of 

 the Sierra Nevada, California. Type locality: "Yosemite Valley, on the Mariposa trail, among rocks. June-July.

 Bolandra imnahaensis M. E. Peck, Rhodora 36: 266. 1934. 



Stamens 1.5-4 dm. high, glandular-puberulent above, somewhat stoutish toward the base; 

 basal and" lower cauline leaves long-petioled ; blades reniform with a narrow sinus, thin, gla- 

 brous, acutely lobed with many triangular-ovate acute lobes and with smaller acute callus-tipped 

 teeth ;' middle cauline leaves short-petioled, with very large, foliaceous, acutely and mucronately 

 toothed stipules ; upper leaves sessile and often auricled, usually more finely dentate, glandular- 

 puberulent ; hypanthium proper greenish or purplish, 5-7 mm. long; sepals linear-lanceolate, 

 long-attenuate, 6-10 mm. long ; petals similar but narrower and still more attenuate, dark purple ; 

 filaments reddish, filiform. 



Rocky banks and cliffs, Humid Transition Zone; northern Oregon and southern Washington, chiefly in the 

 vicinity of the Columbia River Gorge. Also in the Wallowa Mountains and in the Snake River region of eastern 

 Oregon. Type locality: banks of the Willamette River, near Oregon City, Oregon. May-July. 



2. HEMIEVA Raf. Fl. Tell. 2: 70. 1836. 



Glandular-puberulent perennials with fibrous roots from very short bulbiferous root- 

 stocks. Blades of the basal leaves ternately divided to the base, the segments crenately 

 lobed ; cauline leaves with more or less well-developed foliaceous stipules. Flowers in a 

 corymbiform panicle. Hypanthium broadly campanulate, adnate to the lower half of the 

 ovary. Sepals 5, triangular-lanceolate. Petals 5, obovate or oval, narrowed to a short 

 broad claw. Stamens 5, opposite the sepals, erect, inserted on the outer margin of a short 

 thick disk; anthers cordate, 2-celled; filaments purplish, subulate-filiform. Ovary half 

 inferior, 2-celled, with axile placentae; styles erect, distinct; stigmas capitate. [Name 

 Greek, meaning half well, probably in allusion to the shallow hypanthium.] 



A monotypic genus confined to northwestern North America.

Entire plant light green; stem 1-3 dm. high, glandular-pubescent. Basal and lower cauline 

 leaves long-petioled; blades ternately divided to the base, the middle division broadly cuneate 

 and with 3 rounded lobes, 1-2.5 cm. long, the lateral ones oblique and similarly 4-lobed ; petioles 

 glandular-pubescent or glabrous, 3-12 cm. long ; middle cauline leaves similar but smaller, with 

 shorter petioles which are dilated into foliaceous stipules at their bases ; the uppermost merely 

 3-lobed at the apex and enlarged and auriculate at the sessile base, or simply ovate-lanceolate and 

 not lobed sessile and without stipules ; inflorescence short and suhcanitate ; hypanthium turbinate,

 and on the Rocky Mountains." June-July.
