 glabrate, 2-lobed; lobes widely spreading, linear-oblong, obtuse; sepals 

 oblong, 4 mm long, obtuse, purplish at tip, 2-glandular; petals pale blue, 



11 mm long; stamens 10, united below, of two lengths; free part of

26. lonoxalis stolonifera Rose, 1. c, p. 114 et 131. 



A very delicate plant producing long, slender, branching stolons; 

 bulbs small for the genus (4 to 5 mm in diameter), growing in damp 

 moss on perpendicular cliffs; bulb scales thin, black, 3-nerved; leaflets 

 3, 5 to 18 mm long, wedge-shaped, the apex strongly notched and the 

 lobes usually very unequal; peduncles slender, usually longer than the 

 petioles, solitary or few-flowered; sepals 2 mm long; petals violet-purplish, 



12 mm long. 



Type U. S. National Herbarium no. 461983, collected by Dr. C. G.

 previously collected by J. N. Rose at same station (August 7, 1906, 

 no. 11127). 



This is a very peculiar species, differing from all others which I 

 have ever seen in being stoloniferous. The leaflets are also peculiar 

 in having the apex oblique, one lobe usually being much longer than 

 the other.
