SAXIFRAGACEAE (SAXIFRAGE FAMILY) 237 



sparsely ciliate, 2-5 cm. in diameter; petioles 2-3 times as long as the blade, 

 puberulent: raceme secund, bearing 15-20 evenly scattered flowers; flowers 

 white, 2 mm. long, spreading on short petioles: calyx-lobes oblong, obtuse: 

 petals filiform to oblanceolate, 1-nerved, entire, or very rarely parted near 

 the apex into two or three lobes, slightly longer than the calyx: stamens 5, 

 very short. (M. stenopetala Piper, I. c:) Colorado to Montana and far west- 

 ward. 



4. CHRYSOSPLENIUM (Tourn.) L. GOLDEN SAXIFRAGE 



Low and small smooth herbs, with tender succulent leaves, and small 

 corymbose flowers. Calyx-tube adnate to the ovary, the obtuse lobes 4 or 

 5, yellow within. Petals wanting. Stamens 4-8, very short, inserted on a 

 conspicuous disk. Styles 2. Capsule obcordate, flattened. 



1. Chrysosplenium tetrandrum Th. Fries, Bot. Notiser 193. 1858. Flower- 

 ing stems erect, branched above: leaves alternate, reniform-cordate, doubly 

 crenate, or somewhat lobed. C. alternifolium. Arctic in Europe, Asia, and 

 America; said to have been collected in Colorado by Hall and Harbour. 



6. TELLIMA R. Br. 



Low slender perennials with palmately divided or parted leaves, few on 

 the simple stem but more numerous downward. Petioles with stipule-like 

 dilations at base. Flowers in a simple terminal raceme. Calyx campanulate 

 or turbinate, 5-lobed, the base of the tube more or less adnate to the ovary. 

 Petals white or pink, 3-7-parted into narrow lobes. Stamens 10, included. 

 Styles 2-3, very short. Our species frequently bear small grain-like bulblets 

 on the roots, in the axils of the leaves, or in place of flowers in the raceme.

1. Tellima parviflora Hook. Fl. Bor. Am. 1: 239. pi. 78. 1833. Roughish 

 hirsute or scabro-pubescent, 1-3 dm. high: stems sparsely leafy: leaves gen- 

 erally 3-lobed or cleft; the divisions cuneate and once or twice 3-cleft: calyx 

 obconical or at length almost clavate: petals deeply 3-cleft into linear or ob- 

 long divisions: ovary and capsule adnate to the calyx-tube for at least half 

 their length: bulblets rarely produced. Colorado and Utah, northward 

 through the Yellowstone region to British America. 



2. Tellima tenella (Xutt.) \\alp. Report. 2: 371. 1843. Obscurely puberu- 

 lent and glandular, or sometimes nearly glabrous: perennial from bulblets 

 which also give origin to numerous fibrous roots: stems very slender, 1-2 dm. 

 high: leaves small, 3-5-cleft, the divisions again cleft into mostly linear lobes: 

 calyx campanulate, the short lobes often very unequal, sometimes dark 

 purplish-red: petals 3-5-cleft or parted, or even irregularly 7-parted into 

 mostly linear divisions: ovary and capsule free except at the base. [T. glabra 

 (Nutt.) Steud. Nom. Bot. Ed. 2. 2: 665. 1841; Lithophragma australis Rydb.

3. Tellima bulbifera (Rydb.) A. Nels. Glandular-puberulent, 1-2 dm. high: 

 leaves divided to the base; the divisions cuneate or obovate, 3-cleft and the 

 lobes often toothed; the stem leaves usually bearing bulblets in the axils; 

 stipules fimbriate: flowers 3-6, sometimes replaced by bulblets: petals 4-7 mm. 

 long, 3-5-cleft. (Lithophragma bulbifera Rydb. N. Am. Fl. 222; 86. 1905.) 

 From the British boundary to Colorado and California. 



6. SULLIVANTIA T. & G.

 small flowers in paniculate cymules. Calyx campanulate, its base adnate to
