II. MISCELLANEOUS SPECIES 



^Ranunculus Jovis 



A diminutive alpine perennial, 3-4 cm. high : roots fascicled, 

 fleshy, 2— several, nearly vertical, 1-3 cm. long : root leaves few 

 (1-3), trifoliate or trifid, the leaflets broadly linear, about 15 mm. 

 long : petioles 2—3 times as long as the leaflets : stem single, 

 erect, about equaling the erect petioles, bearing a single flower 

 and a sessile, trifoliate or trifid leaf similar to the root leaves 

 (rarely a second petioled leaf) : peduncle 7-15 mm. long : petals 

 oblong-spatulate, 6-7 mm. long, slightly exceeding the somewhat 

 broader sepals : akenes (immature ones only at hand) in a spherical 

 head, oval, the beak stout, subulate, nearly straight, as long as 

 the akene. 



In many respects nearly allied to R. pygmaeus Wahl. but 

 readily distinguishable by the uniform leaves, the longer, not re- 

 flexed petals and the straight beak of the akenes. 



The type no. is 5817, collected on the Thunderer, Yellowstone 

 Park, July 13, 1899, by Messrs. Elias Nelson and Leslie Goodding. 

 Not abundant ; growing on naked " slide soil " where snow drifts 

 had but lately lain.

Several- to many-stemmed from semi-woody roots, erect with 

 usually somewhat decumbent bases, 6-12 dm. high: stems 

 glaucous, strongly striate below : leaves finely pubescent especially 

 upward, not glandular, 3— 5-divided, the divisions broadly cuneate, 

 3 -cleft into more or less toothed lobes, the ultimate segments lan- 

 ceolate and tipped with a minute callosity : inflorescence mostly 

 simple, the bracts linear and the lower leaf-like : the rachis pu- 

 bescent, somewhat glandular : the pedicels densely glandular- 

 pubescent, divaricate-ascending, with linear bractlets : flowers a 

 dull or dark blue, more or less streaked with yellowish-white : 

 sepals lightly pubescent, oblong, 12-14 mm. long: the straight 

 spur about 15 mm. long, its ovate blade about 10 mm. : the lower 

 petals with narrow claw equaling the ovate, bifid, dentate blade, 

 10 mm. long, either sparsely or densely bearded : follicles erect, 1 

 cm. long, conspicuously reticulated with dark lines: seeds evi-
