 and tip with scattered brown glands; peduncles often much Longer than the

Type r. S. National Herbarium no. 346561, collected by J. N. Rose and Walter 

 Hough on Mount Alban near city of Oaxaca, June L6to21, L899 no. 158( 



I also refer here, although it bas much Larger flowers, a specimen collected by 

 B. W.Nelson on the wesl slope of Mount Zempoaltepec, Oaxaca, July, 1894 



This is one of the largest-flowered species of the genus which I have Been in Mexico 

 and would doubtless be worthy of introduction Into cultivation, I have named it 



for my friend Professor Conzatti, of Oaxaca, who conducted rue to the region in 

 which the plant was found and to whom I am under many obligations for com I 

 shown me while in his city. 



Ionoxalis cuernavacana Rose, sp. now 



Bulbs large, deep-seated, clothed without with stout fibers; bulb scale- acute, 

 broad, with numerous strong nerves; leaflets 4. broadly cuneate, rounded or broadly 

 notched at apex, in age glabrate, pale beneath, •'! to 6 cm. long, 2 to l cm. broad: 

 peduncles stout, appearing before the leaves; flowers mostly »i to L2, sometimes 

 reduced to one; sepals oblong, obtuse, gland-tipped; flowers reddish or purplish; 

 petals 12 to 15 mm. Long; stamens of two lengths, the longer toothed on one side. 

 glandular-pubescent, the others hairy. 



TypeTJ. S. National Herbarium no. 346366, collected by .1. N. Rose in deep woods 

 in the canyon above Cuernavaca. Morelos, May, 1899 (no. 4401); also near the same 

 Locality by C. < r. Pringle, June, 1896 (no. 6344). Bulbs were sent home by the writer 

 which flowered in the Botanical < rarden in September, 1899. 



Ionoxalis decaphylla (II. B. K.) Rose. 



OxaiU decaphylla II. B. K. Nov. Gen. & Sp. 5: 538. pi 468. 1821. 



Humboldt's illustration of this species shows a plant with 10 leaflets somewhat 

 cuneate at base and strongly notched at apex. The material which has been referred 

 to this species comes from widely separated station- and show- a considerable vari- 

 ation in the size and shape of the leaflets. A good part of it seems to belong else- 

 where. Material which I collected in the Valley of Mexico is very nearly typical, 

 and. if really so, it will exclude all the northern material. 



Ionoxalis drummondii (A. <iray) Kose. 



OxcUis drummondii A. Gray, PI. Wright. 2: 251. 1853. 



/. drummondii has been reported in Sonora by Torrey, but no specimens are cited 



by Doctor Trelease. I have seen only the Mexican Survey specimens cited by Torrey. 

 The species is characterized by the broadly spreading Lobes <<\ the Leaflets and by 

 the blue flowers. The scale- of the bulbs are thin and 3-nerved, the stamens 

 glabrous. 



Ionoxalis furcata Kose. >p. now Plate XXXV, Figure 2. 



Bulbs solitary, small, globular, covered with the fibers of the old scale-: - 

 ovate, acute, many (more than 10)- nerved; petioles shorter than the peduncles, 

 glabrous: leaflets 7 to i». linear in outline, glabrous, each two-cleft; lob,- about one- 

 fourth the length of the leaflets, diverging, linear, obtuse; peduncles •"• to 7-flowered; 

 involucral bract small, ovate, acute; pedicels .-lender, 10 to pj mm. long; sepals 

 shortly oblong, •'> mm. long, obtuse or rounded at apex, .".-nerved, pubescent; corolla 

 purplish, 10 to 1l' mm. long: stamens all hairy; styles i in specimens Been of one 

 Length and very short; cap.-ule not ,-een.
