 euneate, strongly notchcdj glabrous, pale beneath; pedimele long, longer than the 

 leaves, glabrous, 2 or 3-flo\vered; iuvolueral bracts smallj slightly pubescent; pedi- 

 cels long (2.5 to ') cm.) and slender, souK'what uneiiual; sepals lanceolate, 4 mm. 

 longj obtuse or aentish^ glabrous Avith scarions uiargins; petals white, large, 20 mm.

lonoxalis amplifolia (Trelease) Rose. 



Oxalis (fivenjcns amplifolia Trelease in A. Ciray, Syn. Fl. 1^: 3(58. 1897. 



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

 leaflets, the lobes short and rounded, Ductor Trelease determined it as a form of 

 0. divergeriR^ a species of South Mexico having white flowers. 



I have refeired here tentatively a sijeciinen collected by Palmer near Durango, 

 1896 (no. 297). 



lonoxalis bipartita Kose, sp. nov. 



Bulbs globoi^e, small, the scales many-nervcdj 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-glandnlar at tip; petals pale blue (?), small, G 

 mm. long; stamens 10, united below, of two lengtlis, the longer ones hairy; ovary 

 sessile or nearly so; styles long and short in different flowers; fruit oblongdinear, 

 5 mm. long. 



Type U. S. National Herbarium no. 461290, collected by C. G. Pringle near Cuer- 

 navaca, Morelos, July, 1898 (no. G89C); also collected in the same locality by J. N.

This species resembles 7. slip'data of the Valley of Mexico, but has different leaf- 

 lets, flowers, etc.

Plants glabrous, growing in clusters on rocks in dark (^anyons; bulbs small, the 

 coats 1-nervedj small; leaflets 3, small, wedge-shaped, retuse at apex; peduncles 

 longer than the leaves, 2 to 4-flo\vered; pedicels slender, about 2 cm. long; sepala 

 lanceolate, obtuse, 2.5 mm. long; petals pale lilac, 10 mm. long; 5 longer stauiens 



slightly hairy. 



Type U. S. National Herbarium no, 802425, collected by J. N. Rose in a t^anyon

Perhaps nearest L gregaria, but with different leaflets, fewer and larger flowers, etc. 



lonoxalis confusa Rose, sp. nov. Plate XXXV, Figure 1. 



Resend>ling L furcata; leaflets glaucous and much deeper-cleft (usuall-y to below

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



This species was distributed as 0. dccaphyJla 11. B. K., from which it proves to be 

 very distinct.
