90 BOtANY. 



upper ones cuneiform, incised ; stipules ovate-lanceolate, small, entire or 

 toothed ; flowers crowded, fastigiately cyniose ; bracts short, 3-5-cleft ; calyx- 

 lobes narrowly triangular, exceeding the linear-subulate accessory ones ; petals 

 spatulate, longer than the calyx. — Root thick, fusiform ; flowers small, rose- 

 color. Oregon, (Nuttall.) Near Carson City, (112 Anderson,) and Lake 

 Washoe, (123 Torrey.)

 12.) Viscid-pubescent or glabrate ; stems 3-8' high, several from a thick 

 resinous caudex, exceeding the leaves ; leaflets 2-3" long, about 20 pairs, 3-5- 

 parted, segments cuneate-oblong or linear-oblong, obtuse, entire or bifid ; the 

 single cauline leaf i-1' long, subpinnately divided with entire leaflets ; stipules 

 ovate-lanceolate, entire ; cyme capitate, many-flowered ; calyx turbinate, the 

 lobes triangular-ovate, a little longer than the accessory linear ones ; petals 

 yellow, oblong or oblanceolate, about equaling the shorter sepals, (or subor- 

 bicular and exceeding the calyx ;) stamens 5 ; receptacle long-villous ; carpels 

 1-3, usually 2, (sometimes 6-14.) — The numerous specimens of the collection 

 are constant in their characters, having but 1-3 carpels, 5 stamens, and short 

 narrow sepals, (both before and after anthesis,) and accord in these respects 

 with 1896 and 2071 Brewer. His 1698 and 1723 difier in their much larger 

 conspicuous orbicular petals and in their larger number of carpels. But the 

 number both of carpels and stamens is variable in most of the species of the 

 genus. /. lycopodioides, described as pentandrous, has sometimes 10-15 sta- 

 mens, and /. pygmcea has often as many as 15 carpels. Both differ from L 

 Gordoni in their much less villous receptacle and shallower calyx. On the 

 Upper Platte, (Gordon ;) New Mexico and the Sierras of California. Abund- 

 ant in localities in the Wahsatch and Uintas at an elevation of 9-10,000 feet ; 

 July, August. (345.) 



IvESiA Baileyi. Viscidly pubescent ; stems several, 3-6' high, from a 

 thick perennial branching caudex, slender, branching above, exceeding the 

 leaves ; leaflets 2-3" long, 3-10 pairs, broadly ovate or flabelliform, 3-7- 

 toothed or 3-7-parted ; stipules ovate, entire or 2-3-toothed ; flowers axillary 



'IVESIA, T. & G. Calyx campanulate or cyatliiform at base, 10-oleft. Stamens definite, (5, 10, 

 15, 20 ;) filaments slender, narrowly subulate or fiUform. Carpels few, sometimes solitary, upon a small 

 villous receptacle ; style subterminal. — Leaves pinnate, leaflets very numerous, small, palmately or pe- 

 dately-parted, closely crowded, sometimes quasi- verticillate or imbricate ou all sides of tlie racbis ; petals 

 broadly obovate, scarcely unguiculate, becoming spatulate. Gray, Pj-oo. Arfier. AaaA. 6. 530. 



Tbis genus, as well as the preceding one, is reduced to Foi&nMXla by Bentham and Hooker and by 

 other botanists. However correct this may prove to be, it is thought best here to consider them as
