Type U. S. National Hcrbarinm no. 396715, collecteMl by C. G. Triiiglt' on wet 

 ledges near Guadalajara July 10, 190L* (no. 8659). Here perhaps belongs J. N. Rose's 

 no. 6402 collected in 1901 near the same locality.

loixoxalis galeottii (Tnrcz.) Rose. 



Oralis fjaleoitii Turcz, Bull. Roc. Nat. :Mosc. 31^: 433. 1858. 



Type locality; "Oaxaca, altitude 7,000 ped.;" type collected by Galeotti (no. 



3995). 



Specimens examined: 



Oaxaca: Sierra <le San Felipe, altitude 2,700 and 3,000 ineterH, C. G. Tringle, 



May, 1894 (no. 4660). 



I have seen ]io authentic specimens of this species, l>ut Doctor Pringle'K phmt 



conieH from the same general locality and answers the description fairly well. 



lonoxalis g-onzalesii Rose, sp. nov. 



Bulbs solitary, globular, covered with many fine fd)ers; scales with nuniorous 

 nerves; leaflets about 9, broadly linear, 6 to 7 cm. l^ug, a<'ute, glabratein agt*; pedun- 

 cles 20 to 30 cm, long; umbels many-Howered; pedicels slender, 1 to 2 cm. long; 

 sepals ovate, obtuse, glabrous; petals 1 cm. long, deep purple; styles long, hairy. 



Type U. S. National Herbarium no. 371938, collected by C. Coui^atti and V. Gon- 

 zales on San Felipe, Oaxaca, June 10, 1897 (no. 333). 



This species is pi^haps nearest 0. lasiandra^ but it has differently shaped leaflets, 



glabrous sepals, etc. 



lonoxalis grayi Rose, sp. nov. 



Bulbs surrounded by a thick coat of old fibers; scales thickisli, many-nerved; 

 leaflets 5 to 8, simply notched, ox deeply parted; i»eduucles longer than tlie leaves; 

 flowers purplisli; filaments hairy. 



This is the O.rafls dccaphylla of Gray and of all Ameri(!an Avriters. It differs greatly 

 from the material from the Valley of ^Mexico in the texture of the bulb scah^s and in 

 having numerous veins instead of three. I have referred tentatively to thin species 

 all the material heretofore passing under 0. decaplujlla except that from the A'alley 

 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. decaplujlla, 



lonoxalis gregfaria Rose, sp. nov. 



Plants grondng in thin sheets on the sides and in crevices of dark overhanging 

 cliffs; bulbs numerous, small, in flowering specimens almost entirely absorbed, appar- 

 ently arising from slender rhizomes; leaflets 3, sharply cuneate at base, broad above, 

 retuse, the lobes rounded, 6 to 30 nun. long, pale or sometimes violet-colored, gla- 

 brous or nearly so; peduncles nnich 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 nun. long; 



stamens hairy. 



Type U. 8. National Herbarium no. 40240, collected by C. G. Pringle in the bar- 

 ranca below Cuernavaca, Morelos, 18!H) (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. Appar- 

 ently of the type of 0. martiana, but certainly different, 



lonoxalis hernandesii (DC.) Rose. 



Oxalis hrmtmlesii DC. Prod. 1: 695. 1824. 



This species has a wide distribution and shows considerable variation in the size 



and shape of tlie leaflets. The leaflets, however, are never retuse. 

 In tlie IJ. S. National Herbarium we have some 16 sheets of this species.
