 Nobles Kanch, New Kiver, Jepson 1985 ; Willow Creek, Trinity Eiver, Tracy 3447 ; Snow Mt., n. 

 Lake Co. (Zoe 4:171). 



Var. fishiae Jepson. Bush 2 to 4 feet high, often growing up through brush and reclining 

 on it; outer sepals puberulent; inner (large) sepals glabrous or sometimes puberulent; wings 

 purple; keel yellow. — Kocky slopes in the foothills and mountains, 1500 to 3000 feet: South- 

 ern California from Santa Barbara Co. to San Diego Co. South to Lower California. The 

 flower in structure and details of pubescence is remarkably like that of P. cornuta. The un- 

 dulate auricles on inner angles of hood may be present in both forms — the variety and the 

 species. In the variety the large sepals are usually subglabrous but may be puberulent. 

 Notching of the lateral sepals at apex is not a constant character in either form.

3. P. subspinosa Wats. Spiny Poltgala. Steins several, slender, erect, aris- 

 ing from a much-branched underground root-crown, thus forming a low tuft 2 to 

 6 inches high; taproot often very woody, 2 to 8 lines in diameter; branchlets wholly 

 spinose, straight, leafless, 5 to 7 lines long; leaf-blades ovate, acute, microscopically 

 puberulent, sessile, 3 to 7 lines long; flowers solitary and axillary, 4 to 5 lines long, 

 with membranous bracts, on colored pedicels 3 to 4 lines long; pedicels reflexed in 

 age; sepals pink; petals linear, pinkish- and yellowish-marked, truncatish and ero- 

 sulate at the dark purple tips; keel whitish and pinkish, with a broad yellow beak 

 as long as or longer than the sac; capsules suborbicular, short-stipitate, veiny, 3 

 lines long

4. P. acanthoclada Gray. Desert Polygala. Spiny shrub I/2 to 2i/^ feet

 on very short but distinct callus-like petioles; flowers yellowish-white, 2 lines long; 

 petals purplish-tinged at apex, very shortly and very unequally 2-lobed at apex;

 Desert; eastern Mohave Desert in the Shadow Mts. and New York Mts. East to 

 Arizona and Colorado. Julj^ 



Habit note. — Divaricately, numerously and shortly branched, this species as it occurs in the 

 eastern Mohave Desert forms low circular mounds 1 to 5i/^ feet broad and 6 to 14 inches high 

 which probably present a denser weave in the plant body than is found in any other woody species 

 in California. It grows near Barnwell ; it has also been collected at the Yucca Grove road sta., 

 east of Halloran Spr., Shadow Mts. (Jepson 15,805) ; and it is reported from Cottonwood Spr. 

 (Peirson).
