1.5 cm. long, mucronate, entire or appressed-serrulate, glabrous or 

 sparingly pilose-setulose ; the lower equalling the capillary petioles, 

 the upper short-petioled : flowers few, terminal and axillary, on joedicels 

 2 cm. or less in length: involucre short-campanulate, 2 mm. long, ap- 

 pressed-setulose, the deltoid-oblong truncate erose lobes incurved ; glands 

 4, dark, with pale oblong-lanceolate blunt appendages 1 to 1.5 mm. long; 

 false gland similar : capsule rugulose, 4 mm. high : seed oblong-ovoid, 

 minutely puncticulate, gray or gray-green, mottled with olive or brown. — 

 MoRELOS, on mossy ledges of Sierra de Tepo-xtlan, alt. 2,310 m., Sept. 

 12, 1900 (C. G. Primjle, no. 8443). 



E. (Cyttarosperraum) calcicola. Annual, freely branching, 5 or 

 6 dm. high, the slender stem and branches viscid-setulose with long pale 

 hairs : leaves broad-ovate, rounded or bluntish at tip, truncate or sub- 

 cuneate at base, the lower 2 cm. long, the upper much smaller, setulose 

 on both faces, dark above, pale beneath, about equalling the capillary 

 petioles: flowers axillary on capillary pedicels 1 to 1.5 cm. long: in- 

 volucre broad-campanulate, green and yellow, 1 mm. long, the short in- 

 curved cuneate lobes lacerate ; glands 4 with 3 finger-like appendages ; 

 the false gland slightly larger, with 4 appendages : ovary glabrous. — 

 Guerrero, limestone mountains above Iguala, alt. 1,230 m., Oct. 5, 

 1900 (C. G. Pringle, no. 8398). Closely related to E. astroites, F. & 

 M., but the stem conspicuously setulose. and the pedicels much longer, 



E. LAXCiFOLiA, Schl., var. villicaulis. Stems more or less villous 

 with crisp jointed hairs: leaves rhombic-ovate, acutish, green and lucid 

 above, pale and more or less villous beneath : involucre campanulate, 

 pilose or glabrate, 3 or 4 mm. long; lobes truncate, serrate ; glands 1 or 

 2 associate, hoof-shaped ; false glands 3, columnar, truncate, one-third 

 longer than the lobes : capsule (young) pilose, 5 mm. long, with rounded 

 lobes : seed (young) short-oblong, 2 or 2.5 mm. long, pale brown. — 

 Chiapas, mountain-slope above Ococingo, March 13, 1896 (C. & E. 

 Seler, no. 2214). Distinguished from the species by its pubescence, in- 

 volucral lobes, and false glands. In E. lancifoUa the iuvolucral lobes are 

 fimbriate, equalling or slightly exceeding the subalate false glands. 



Pernettya ovata. Branches pale brown, minutely puberulent or 

 glabrate : leaves ovate, sliort-petioled, 1 to 1.5 cm. long, pale and mi- 

 nutely canescent-tomentulose toward the rounded base ; margins finely 

 appressed-serrate, the youngest glandular-ciliate, as are the lower faces 

 of the young leaves : infloi'escences axillary, subsessile, all the parts 

 glabrous, the deciduous bracts sometimes with erose margins : flower- 

 ing calyx 3 mm. long, cleft half-way to the base into deltoid smooth-
