Oxalidaceae novae mexicanae. 



255 



long; 5 of the stamens a little longer than the others: filaments glabrous 

 below, slightly hairy at the top. 



Type U. S. National Herbarium no. 304004, collected by Dr. C. G. 

 Pringle on Sierra de las Crucis, Mexico, altitude 3000 meters, August 13, 

 1896 (no. 6439). 



2. lonoxalis amplifolia (Trelease) Rose, I. c, p. 110. 



Oxalis divergent amplifolia Trelease in A. Gray, Syn., Fl., I 1 , 368; 

 1897. 



This form seems to deserve specific rank. It is characterized by 

 broad obcordate leaflets, the lobes short and rounded. Doctor Trelease 

 determined it as a form of 0. divergens, a species of South Mexico having 

 white flowers. 



I have referred here tentatively a specimen collected by Palmer near 

 Durango, 1896 (no. 297). 



3. lonoxalis bipartita Rose, 1. c, p. 110. 



Bulbs globose, small, the scales many-nerved, ciliate; buds and 

 young parts hairy; leaflets 3, a little hairy, deeply 2-lobed; lobes widely 

 spreading, linear and elongated, obtuse; sepals 3 mm long, obtuse, 

 2-glandular at tip; petals pale blue (?), small, 6 mm long; stamens 10, 

 united below, of two lengths, the longer ones hairy; ovary sessile or 

 nearly so; styles long and short in different flowers; fruit oblong-linear. 

 5 mm long. 



Type U. S. National Herbarium no. 461290, collected by C. G. 

 Pringle near Cuernavaca, Morelos. July, 1898 (no. 6896); also collected 

 in the same locality by J. N. Rose, May. 1899 (no. 4365). 



This species resembles I. stipitata of the Valley of Mexico, but has 

 different leaflets, flowers, etc. 



4. lonoxalis compacta Rose, 1. c, p. 110. 



Plants glabrous, growing in clusters on rocks in dark canyons; 

 bulbs small, the coats 1-nerved, small; leaflets 3, small, wedge-shaped, 

 retuse at apex; peduncles longer than the leaves, 2 to 4-flowered; pedicels 

 slender, about 2 cm long; sepals lanceolate, obtuse, 2,5 mm long: petals 

 pale lilac, 10 mm long; 5 longer stamens slightly hairy. 



Type U. S. National Herbarium no. 302425, collected by J. N. Rose 

 in a canyon near top of the Sierra Madre just below the little village 

 of Santa Teresa, Tepic, altitude about 2400 meters, August 12, 1897 

 (no. 3448). 



Perhaps nearest I. gregaria, but with different leaflets, fewer and 

 larger flowers, etc. 



5. lonoxalis confusa Rose, 1. c, p. 110, pi. XXXV, fig. 1. 

 Resembling I. furcata; leaflets glaucous and .much deeper-cleft 



(usually to below the middle); sepals glabrous; flowers more numerous 

 and smaller; capsule linear-oblong, 7 mm long; stamens of two lengths, 

 the short ones glabrous, the long hairy. 



Type U. S. National Herbarium no. 305682, collected by Dr. C. G. 

 Pringle on wet banks near Guadalajara. Jalisco, June, 1889 (no. 2789).
