plant resembling H. sessilifiora, Benth., but well distinguished by its 

 coarser habit, larger leaves and pedicelled flowers, narrower capsule, 

 thicker style, and larger seed. 



Dyschoriste saltuensis. A slender sufFrutescent plant : stems 

 branching, subtetragonal, densely covered with short appressed hairs, 

 ciliate at the nodes : leaves lanceolate, obtuse at the tips, tapering below 

 into short petioles, the lower cauline 6 cm. long, li cm. wide, the upper 

 scarcely half as large, above covered with obscure linear markings, be- 

 neath strigillose-pubescent on the midrib : flowers axillary, solitary, or in 

 glomerules of 2 to 5 : peduncles 3 or 4 mm. long : bracts minute : calyx 

 hirsute, 8 or 10 mm. long, divided half way to the base into 5 lance- 

 subulate lobes : corolla light purple, pubescent without, \\ cm. or less in 

 length, the slender tube equalling the calyx and then spreading into a 

 campanulate throat ; lobes oblong, truncate, 4 ram. long : stamens didy- 

 mous, hirsute ; anther-bases mucronate : style hirsute : mature fruit not 

 seen, but the young capsule oblanceolate, glabrous, hardly equalling the 

 calyx. — Common among oaks in the higher mountains, January, 1895 

 (uo. 506). 



Ruellia albiflora. A small shrub : the pale brown bark covered 

 with prominent ovate lenticels ; upper branches, with the leaves and 

 calyces, covered with pellucid or black granules : leaves mostly on the 

 upper branches, oblong-lanceolate or narrowly ovate, tapering about 

 equally to the bluntish tips and the short petioles (4 to 7 mm.) ; leaves of 

 the primary branches 4 to 10 cm. long, Ih to 4^ cm. wide, slightly ap- 

 pressed-pubescent on the midribs beneath, and with a few linear markings 

 upon the epidermis above ; those of the branchlets crowded and smaller, 

 liecomin" even 1 cm. in lenoth : flowers subsessile in the axils of the 

 upper leaves, subtended by liuear-spatulate bracts about equalling the 

 calyx: calyx minutely puberulent, the tube 4 mm. long, the 5 lance- 

 subulate lobes 6 or 8 mm. long : corolla white, puberulent without ; the 

 tube slender, 2 cm. long, spreading into a narrowly obconic throat 1 cm. 

 high ; limb with ovate lobes 8 mm. long : filaments sparingly pubescent ; 

 anthers linear, 2 mm. long : style hirsute ; stigma 1 mm. long : pod nar- 

 rowly obovate, 12 mm. long, 4 mm. wide, somewhat dorsally compressed, 

 blunt above, subcuneate below, minutely white-puberulous ; seeds 2 to 4, 

 suborbicular, d\ mm. long, appressed-pubescent, tipped by a minute white 

 caudate appendage. — Collected at Acapulco, November, 1894 (no. 49) ; 

 and formerly at Armeria (Palmer, 1891, no. 1274). This shrub is very 

 showy in flower, and at Acapulco it grows abundantly in river bottoms 

 and low rich spots among the mountains, where it is called Tronador.
