75. Thysanocarpus curvipes madocarpus Piper, 1. c, p. 306. 



Differs from the species in having its pods glabrous instead of 

 puberulent. 



Prom field observations this seems worthy of subspecific rank. 

 While both forms may occur close together, yet so far as my obser- 

 vations go a particular colony of plants is of one form or the other; 

 the two do not occur mixed. 



Mr. M. L. Pernald kindly examined the type of T. curvipes in the 

 British Museum and writes that the pods are puberulent, a point not 

 brought out in the original description. 



Specimens examined: Pullman, Elmer, 79 (type); Wawawai, Piper 

 1480 in part; Spokane, Henderson, June, 1892; Tacoma, Plett 886; 

 near Clarkston, Hunter 49; Waitsburg, Horner 76 in part.

 the type. 



77. Saxifraga odontophylia Piper, 1. c, p. 314. 



Perennial by stout rootstocks, not bulbous, entirely glabrous up to 

 the inflorescence; leaves all basal, reniform-orbicular, somewhat fleshy, 

 coarsely and evenly dentate with 15 to 25 teeth, 2 to 8 cm broad; petioles 

 usually 2 to 3 times as long as the blade; scapes 10 to 40 cm high: 

 inflorescence a loose, erect panicle, glandular; bracts linear, the lower 

 more or less dentate or occasionally foliaceous; pedicels slender; calyx 

 5-parted, the lobes oval, obtuse, 2 mm long, reflexed in anthesis; petals 

 white, orbicular and unguiculate, longer than the calyx; filaments spatu- 

 late, acuminate; ovary free; capsules usually purple, somewhat inflated. 

 7 to 8 mm long, cleft to the middle, the beaks becoming divaricate. 



This species has long passed in American herbaria as S. punctata L.+ 

 a rare European species. Among American species it can only be con- 

 fused with S. nelsoniana Don, which is a smaller plant with lobed rather 

 than dentate leaves, pubescent stems and inflorescence, elliptical un- 

 clawed petal's, and a more or less condensed flower cluster. S. odonto- 

 phylia ranges from British Columbia to New Mexico and California.
