JOHNSON: A REVISION OF THE SECTION BORAPHILA 53 



The above description is borrowed from the original of Coville (2) 

 who described the plant as a variety of Saxifraga integrifolia Hook. The 

 type specimen, which has not been available for study, is in the United 

 States National Herbarium. "No. 1705, Death Valley Expedition, Col- 

 lected August 25, 1891, about eight miles northwest of Whitney Meadows 

 on the Headwaters of Kern River, Sierra Nevada, Tulare County, Cali- 

 fornia, by Frederick V. Coville." Coville states that the plant is found in 

 the Rocky Mountains also. Collections from various localities show several 

 distinct forms referred to 5". Sierrae of which only those are here given 

 recognition which conform most closely to the descriptions of Coville. 

 The others constitute such a confusing array of forms that the problem of 

 their status must await further study. In addition all Rocky Mountain 

 specimens referred to Micranthes arnoglossa Small are included here.

Saxifraga winnebagoenis sp. nov. 



Receptaculum ovario non alte adnatum; folliculi praeparvi globosi 

 superne multo contracti stylis brevissimis stigmatibus parvis; filamenta 

 subulata gracilia brevia ; sepala parva oblonga vel ovata vel deltoidea acuta 

 base evidente coalita reflexa; petala non adsunt; semina ovata longitu- 

 dinaliter tuberculata. 



Receptacle shallow; follicles very small, globose, slightly spreading, 

 abruptly contracted above into very short beaks; stigmas small. Filaments 

 subulate, slender, 1.7 mm., exceeding the sepals. Sepals 1.3-1.5 mm., oblong 

 or ovate to triangular, acute, plainly united at base, green, reflexed; lateral 

 nerves 2, reaching to the middle. Petals wanting in specimens. Seeds about 

 1 mm., broadly ovoid- fusiform, carinate, with longitudinal ridges of short 

 tuberculate teeth. Hairs of various lengths, uniseriate ; glands oblong, some- 

 times broadest at top, consisting of a row of superposed cells. Leaves 12 

 cm. long and less, few, elliptic-lanceolate or obovate, minutely denticulate to 

 subentire, shallowly or Inconspicuously repand, obtuse to acute, strigillose 

 pubescent on both sides, somewhat leathery, gradually contracted into short, 

 sheathing bases. Scape erect, solitary, about 35 cm., yellowish-green, loosely 

 glandular-pubescent, branching above. Inflorescence racemose-cymose, nar-
