MISCELLANEOUS Sl'ECIES. 



Acacia subangulata Rose, sp. nov. 



A spreading shrub, 5 to 7 m. high; branches somewhat angled, bearing short 

 straight prickles, more or less puberulent; stipules small, somowbat membranaceous, 

 2 to 4 mm. long; petiole short (13 mm. long), bearing a large but inconspicuous and 

 depressed oblong gland near the middle; main rachis somewhat 4-angled. sometimes 

 prickly; pinnse about 7 pairs; stipels minute; leaflets 20 to 30 pairs, oldong, 5 to 7 

 mm. long, midnerve strongly eccentric, thickish, puberulent; inllorescence a large 

 spreading naked panicle; heads more or less verticillate, on peduncles less than one

Collected by Mr. C. G. Pringle on calcareous hills near Tehuacan in the eastern 

 part of the State of Puebla, August 6, 1807 (No. 0775). 



This Acacia comes nearest A. lerlandkri, but has fewer pinine and leaflets, the 

 latter larger, 1 bicker, and greener, etc. 

 Brongniartia lunata Rose, sp. nov. 



A low shrub; brandies slender, pubescent; leaves 1.5 to 2 dm. long; stipules 

 lunate-renilorm, but the upper lobe acute; leaflets distant, 3 to 5 pairs, oblong, .18 

 to 55 mm. long, rounded and apiculate, above pubescent, becoming glabrate in age, 

 beneath paler, appressed-pubescent, and in age reticulated ; flowers in pairs in the 

 axils; peduncle L J .5 mm. long, glabrous; subtending bracts not seen; calyx 15 mm. 

 long, glabrous without; corolla 25 mm. loug; legume not seen. 



Collected by J. N. Rose in the State of Durango, east of Huasemote, August 15, 

 1807 (No. 2314). Very different from the above and all other species which I have 

 seen in the shape of its stipules. 

 Brongniartia diffusa Rose, sp. nov. 



Low, difinse shrub, about 1 dm. high, glabrous or nearly so ihroughout; stipules 

 oblong to ovate, 6 to 8 mm. long, acute, deciduous; leallets 3 to 9 pairs, oblong, 12 to

 subtending the flowers broadly ovate, 8 mm. long, scarious, caducous; calyx 8 mm. 

 long, the lobes acute, the 2 upper lobes united to near the top, glabrous without, 

 pubescent within; corolla 18 mm. long, purplish; ovary glabrous, stipitate, 3-ovuled; 

 immature pods, 35 mm. long, 12 mm. broad.

This species is very distinct from any other species of this genus which 1 have 

 seen.

 glabrate ; leaves 2.5 cm. long, without glands ; stipules wanting; leaflets 2 or 3 pairs, 

 becoming glabrate in age, mostly oblong, sometimes orbicular or obovate, somewhat 

 oblique at base, rounded at apex, sometimes apiculate; inllorescence and flowers 

 similar to the above; legumes 1.8 to 2.3 dm. long, t; mm. wide.
