passing under 0. decaphylla except that from the Valley of Mexico, 

 although there may be other forms which should be taken out. I have 

 taken for the type U. S. National Herbarium no. 14731, the first specimen 

 (Wright's no. 909) wrongly referred to 0. decaphijlla. 



14. lonoxalis gregaria Rose, 1. c, p. 112. 



Plants growing in thin sheets on the sides and in crevices of dark 

 overhanging cliffs; bulbs numerous, small, in flowering specimens almost 

 entirely absorbed, apparently arising from slender rhizomes; leaflets 3, 

 sharply cuneate at base, broad above, retuse, the lobes rounded, 6 to 

 30 mm long, pale or sometimes violet-colored, glabrous or nearly so; 

 peduncles much longer than the leaves, many-flowered; pedicels very 

 slender, elongated, sometimes 25 mm long; flowers small; calyx lobes 

 shortly oblong, obtuse, 1 to 2 mm long, glandular at tip; petals pale 

 lilac, 6 to 8 mm long; stamens hairy. 



Type U. S. National Herbarium no. 40240, collected by C. G. 

 Pringle in the barranca below Cuernavaca, Morelos, 1896 (no. 6343); 

 also collected at the same locality by J. N. Rose, May, 1899 (no. 4437). 



It differs from most of the other described species in its clustered 

 bulbs. Apparently of the type of 0. martiana, but certainly different. 



15. lonoxalis hernandesii (DC.) Rose, 1. c, p. 112. 

 Oxalis hernandesii DC. Prod. I, 695; 1824. 



This species has a wide distribution and shows considerable 

 variation in the size and shape of the leaflets. The leaflets, however, 

 are never retuse. 



In the U. S. National Herbarium we have some 16 sheets of this 

 species. 



16. lonoxalis jacquiniana (H. B. K.) Rose, 1. c, p. 113. 

 Oxalis jacquiniana H. B. K., Nov. Gen. & Sp., V, 235; 1821. 

 Type locality: „Prope Real del Monte". 



17. lonoxalis jaliscana Rose, 1. c, p. 113, pi. XXXV, fig. 3. 



Bulbs solitary, globular; scales closely many-nerved; petioles scarcely 

 half as long as the peduncles, glabrous; leaflets 5 to 8, broadly cuneate, 

 6 to 12 mm broad above, deeply 2-notched or slightly lobed, the lobes 

 broad and obtuse; flowers 5 to 8; pedicels slender, 10 to 12 mm long; 

 sepals 5 mm long, oblong, acute, glabrous; corolla purplish, 15 mm long 

 styles (in specimens seen) all very short and glabrous; capsule oblong, 

 about twice as long as the sepals, glabrous. 



Type U. S. National Herbarium no. 396712, collected by C. G. Pringle 

 near Guadalajara, Jalisco, July 1 1902 (no. 8646), also collected near 

 the same locality by Dr. E. Pal Jr in 1896 (no. 68). The latter plant 

 was referred by Dr. S. Watson to Oxalis decaphylla, from which it is- 

 readily distinguished by its bulb scales, leaflets, etc. 



18. lonoxalis latifolia (H. B. K.) Rose, 1. c, p. 113. 



Oxalis latifolia H. B. K., Nov. Gen. & Sp., V, 237, pi. 467; 1823. 

 This species as heretofore understood has had a wide range ex- 

 tending, according to some authorities, from the southern United States
