SiDA Alamosaxa. I'erenniul (?), herbaceous, erect, slender and 

 brauchiug, finely «ilaiidiilar-|)ubescent : stipules filil'orin, 2 to 4 lines 

 long ; leaves on slender petioles, ovate to lanceolate, acuminate, more 

 or less cordate at base, lallier acutely serrate, 2^ inches long or less, 

 somewhat hairy especially on the nerves (not glandular-pubescent), 

 the hairs simple or forked : peduncles axillary, slender, mostly an inch 

 long or more: corolla "orange" (apparently white), 3 lines long, ex- 

 ceeding the acuminate-toothed calyx : carpels 5, little over a line long, 

 ovate, glabrous except the summit, thin-walled, terminating in a con- 

 tracted truncate dehiscent cavity above the seed. — Collected at Ala- 

 mos, Sonora, by Dr. Edward Palmer (u. G83j in September, 1800. 

 Closely resembling S. uhnifolia in habit, but more glandular-pubes- 

 cent, with longer filiform stipules, more acutely serrate leaves, and 

 especially distinguished by the unusual character of the carpels. 



Ayenia Berlandieri, Watson, Proc. Am. Acad. 21. 419, in part. 

 Mr. Pringle has collected flowering specimens which accord in foliage 

 with the original specimens of Berlaudier, but with different flowers 

 from those of the plants of Dr. Palmer's Cliihuahuan collection upon 

 which my description was largely based. It becomes necessary to 

 separate the two forms and to redescribe this species. — Plant 3 to 6 

 feet high, the herbaceous branches more or less stronofly angled and 

 sulcate : leaves ovate to ovate-lanceolate, acute, rounded or slightly 

 cordate at base, densely pubescent beneath with a soft stellate tomen- 

 tum, greener above, serrulate, 2 to 4 inches long: peduncles 1-2-flow- 

 ered, fascicled in the axils or in a naked terminal inflorescence: calyx 

 and petals dark purple, the former 2^ lines long, the blade of the 

 petal parted into two broad quadrate aud truncate lobes : anthers 3- 

 celled : ovary and capsule rather long-muricate. — Berlandier ; Prin- 

 gle (n. 3309), in low lands at Las Palmas, San Luis Potosi. 



Ayenia Jaliscana. Differing from A. Berlandieri in its more 

 terete branches and thinner, less pubescent, and more coarsely toothed 

 leaves; flowers smaller and paler, the sepals li lines long, and the 

 lobes of the petals oblong and acutish ; anthers 2-celled and capsule 

 more shortly miiricate. — Southwestern Chihuahua, Dr. E. Palmer 

 (n. I'J and 83), and apparently also at Guaymas (n. 2-13 of his 1887 

 collection). 



BuNCHOsiA Prtnglf.i. a shrub or small tree (12 to 20 feet high) ; 

 branchlets and inflorescence appressed-hairy : leaves thin, oblong, ob- 

 tusely short-acuminate, acutish at base, eglandular, glabrous above, 

 sparsely hairy beneath, 3 or 4 inches long by 1 or 2 broad, on petioles 

 3 lines long : racemes mostly solitary in the axils and simple, shorter
