ROSE^MEXICAN AND CENTRAL AMERICAN PLANTS. Ill 



at apex, 2 to 3 cm. long, somewhat hairy even in age, glaucouf^ beneath, the margin 

 and tip with scattered brown glandjj; peduncles often much longer than the leaves 

 and appearing with them, 20 to 30 cm. long; flowers numerous, on slender pedicels; 

 sepals lanceolate, 5 to 8 mm. long, obtuyish, thin, purplish-margined, bearing a 

 brown gland at tip; flowers deep purple; petals 12 to 20 nun. long; fdaments a little 

 pubescent; styles hairy. 



Type U. S* National Herbarium no, 34()561, collected by J. N. Rose and Walter 

 Hough on Mount Alban near city of Oaxaca, June 16 to 21, 1899 (no. 4586). 



I also refer here, although it has much larger flowers, a spet:imen collected by 

 E.W.Nelson on the west slope of Mount Zempoaltepec, Oaxaca, July, 1894 (no. 



550). 



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

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

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

 which the plant was fuuiid and to whom I am under many obligations for courtesies 

 shown me while in his city, 



lonoxalis cuernavacana Rose, sp, nov. 



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

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

 notched at apex, in age glabrate, pale beneath, 3 to 6 cm. long, 2 to 4 cm. broad; 

 pedunc^les stout, appearing before the leaves; flowers mostly G to 12, 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, 



TypelJ. S. National Herbarium no. 346306, collected by J. N. Rose in deep woods 

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

 locality by C. G. Pringle, June, 1S96 (no. 6344). Bulbs were sent home by the writer 

 which flowered in the Botanical Garden in September, 1899. 



lonoxalis decaplxylla {II. B. K,) Rose, 



OxalU decaphylla H. B. K. Nov. Gen. & ^i>, 5: 538, pi 408. 1821. 



Humboldt's illustration of this species shows a plant w^ith 10 leaflets somewhat 

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

 to this species comes from widely separated stations and shows a considerable vari- 

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

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

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



lonoxalis drummondii (A. Gray) Rose. 



Oxalls drummonda i\. Gray, PL Wright, 2: 251. 1853, 



L 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 of the leaflets and by 

 the bhie flowers. The scales of the bulbs am thin and 3-nervedj' the stamens 

 glabrous, 



lonoxalis furcata Rose, sp. nov. Plate XXXV, Figure 2, 



Bulbs solitary, small, globular, covered wdth the fibers of the old scales; scales 

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

 glabrous; leaflets 7 to 9, linear in outlinej glabrous, each two-cleft; lobes about one- 

 fourth the length of the leaflets, diverging, linear, obtuse; peduncles 3 to 7-flowered; 

 involucral bract small, ovate, acute; j)edicels slender, 10 to 12 mm. long; sepals 

 shortly oblong, 3 mm. long, obtuse or rounded at apex, 8-nerved, pubescent; corolla 

 purplish, 10 to 12 mm. long; stamen? all hairy; styles (in specimens seen) of one 

 length and very short; capsule not seen.
