ErPATORIUMS OF VENEZT'ELA. 335 



Var. SUBVELUTINUM (DC.) Bak. Stem covered with a very fine 

 incurved pubcrulence; leaves puberulent to sparingly tomentellous 

 beneath. — Bak. 1. c. 282. — Mkrida: near Tovar, Fcndler, no. 19r)2 

 (Gr._). 



Without atlequate material to determine the extent to which the 

 forms of this variable species are actually connected by intergradation, 

 it has seemed best provisionally to accept Baker's disposition of the 

 present plant as a variety of E. squalidum. It may be remarked that 

 the leaves of the Fendler specimen are larger and more pointed than 

 in any other material of E. squalidum seen by the writer, but concomi- 

 tant differences of significance have not been observed. 



10. E. oxYLEPis DC. Shrubby, 1-2 m. high, much branched, 

 scented; branches ascending, terete, somewhat woody, grayish- 

 pubescent; leaves opposite, elliptic-ovate to ovate-lanceolate, sub- 

 entire to crenate-serrate (often mth a single tooth or sometimes with 

 2-1 teeth on each side), slightly roughened above, velvety-hirsute 

 beneath, 2.8 cm. long, 1.6 cm. wide, 3-nerved from the base; petiole 

 2-4 mm. long; panicle much branched, very leafy; heads 14-20- 

 flowered, 7-10 mm. high; involucre cylindrical, acute in bud; scales 

 stramineous, firm, regularly graduated in 5-7 series, closely appressed, 

 glabrous, slightly lucid, lanceolate to lance-linear, gradually narrowed 

 to a really acute or (especially in the case of the outer) somewhat 

 darkened and obtuse actual tip; corollas purple, cylindrical, glabrous. 

 — Prod. V. 145 (1836); Bak. in Mart. Fl. Bras. vi. pt. 2, 284 (1876), 

 excl. syn. E. -pungcns Gardn. 



[Var. typicum. Heads about 1 cm. long; corollas 4-5 mm. long; 

 achenes 3-4 mm. long. — Plains of Brazil, in provinces of Goyaz, 

 Minas Geraes, Sao Paulo, etc.] 



Var. CARACASANUM (Sch. Bip.) Hieron. Closely similar in habit, 

 foliage, pubescence, etc.: heads somewhat smaller; involucre about 

 7 mm. long; corollas and achenes proportionally shorter. — Hieron. 

 in Engl. Bot. Jahrb. xxviii. 567 (1901), as earacasana. E. caracasanum

 Moritz, no. 65, ace. to Hieron. 1. c. Merida: on stony hills near 

 Incantados de Petare, Gollmcr, ace. to Hieron. 1. c. Merida: near 

 Tovar, alt. 671 m., Fendler, no. 1951 (Gr.), identified with the type 

 material at the Royal Botanical Museum in Berlin by Dr. J. M. 

 Greenman. 



11. E. XESTOLEPis Robinson (see p. 261). Stems round, woolly
