BLAKE—REVISION OF FLOURENSIA. 401 
SPECIMENS EXAMINED: 
Hipatao: Near Ixmiquilpan, 1831, Schiede & Deppe 1564 (Ber., photo. and 
fragm. G). Ixmiquilpan, Ehrenberg 35 (Ber.). Mountains, Ixmiquilpan, 
August, 1905, Purpus 1458 (type collection; G). Ixmiquilpan, 1905, Rose, 
Painter & Rose 9025 (N). 
This apparently local species is distinguished from all except F. heterolepis by its 
narrowly oblong-elliptic to lanceolate, very glutinous, entire leaves and few long- 
peduncled, rather large heads. Ehrenberg’s plant in the Berlin Herbarium was 
labeled by Schultz Bipontinus more than sixty years ago as a new species of Flourensia, 
under a name which has already been used three times for true Flourensias originally 
published under other generic names. 
The number of the type collection is given as 1456 in the original description, but 
Mr. Brandegee informs me that the correct number is 1458. 
9. Flourensia heterolepis Blake, Contr. Gray Herb. n. ser. 54: 186. 1918. 
Viguiera (?) glutinosa Rusby, Mem. Torrey Club 4: 211. 1895. Not F. glutinosa 
Blake, 1913. 
Shrub; stem (or branch) slender, remotely leafy, olivaceous, round-angled, strongly 
resinous; leaf blades 7.5 to 13 cm. long, 1.4 to 2.5 cm. wide, lanceolate or narrowly 
elliptic-lanceolate, acuminate or acute at both ends, mucronate, resinous, entire, 
densely prominulous-reticulate, with about 13 pairs of lateral nerves and yellowish 
white costa; petioles marginless, 6 to 16 mm. long; heads 3 or 4, terminal and axillary 
toward ends of branches, about 4.5 cm. wide, on sparsely linear-bracted peduncles 
3 to 8 cm. long; disk 1 to 1.2 em. high, 1.5 to 1.7 cm. wide; involucre 3-seriate, very 
glutinous, 11 to 12 mm. high, the outer phyllaries somewhat shorter, lanceolate, acumi- 
nate to a callous apex, herbaceous, the inner longer, with a rhombic-obovate body (3.5 
mm. wide), laterally chartaceous-coriaceous and glandular-fimbriatulate, and an 
abruptly narrowed lanceolate herbaceous tip; rays about 14, oblong, glutinous, gla- 
brous, 2.2 cm. long, 7 mm. broad; disk corollas 5 mm. long (tube 0.6 mm.); pales 
scarious-margined and lacerate above, with slightly widened deltoid cuspidulate erose 
apex, 8 mm. long; achenes (immature) cuneate, densely silky-pilose, 3.5 mm. long; 
awns 2, 2.7 mm. long; squamellae none. 
Tyrr Locauity: Cochabamba, Bolivia. 
SPECIMENS EXAMINED: 
Boutvia: Cochabamba, 1891, Bang 977 (type collection; B, G, N). 
This species, curiously similar in general features to the Mexican F. restnosa, is 
readily separated from it by its broad-based inner phyllaries. 
10. Flourensia microphylla (A. Gray) Blake, Proc. Amer. Acad. 49: 374. 1913. 
Encelia microphylla A. Gray, Proc. Amer. Acad, 15: 37. 1879. 
Much-branched shrub, about 1 meter high, with grayish brown bark, the young 
branchlets purplish brown, striate, subcanescently hispid-pilose with incurved hairs; 
leaf blades 1.5 to 2.5 cm. long, 5 to 10 mm. wide, ovate to elliptic-ovate, acute at both 
ends, cuspidate, entire but somewhat wavy-margined, more or less scabrous-pubescent, 
particularly beneath and on margin, somewhat resinous, densely and finely prominu- 
lous-reticulate, with about 7 to 9 pairs of obscure lateral veins; petioles pubescent, 1.5 
to 4 mm. long; heads solitary at tips of branches, 2.5 to 2.8 cm. wide, on bracteate 
peduncles 3 to 12 cm. long; disk 11 to 14 mm. high, 12 to 15 mm. thick; involucre 2 or 
3-seriate, equal or the inner phyllaries elongate, 10 to 15 mm. high, the phyllaries ovate- 
lanceolate to narrow-lanceolate, acuminate, herbaceous, rather densely and sub- 
canescently hispid-pilose, more or less glabrate in age; rays about 10, golden-yellow, 
oval, emarginate at apex, glabrous, 1 cm. long, 4 mm. wide; disk flowers glabrous, 6 
mm. long (tube 1 mm.), the throat cylindric or cylindric-funnelform; pales rather 
thin, narrowed toward the blackish green apex, glandular on the keel, ciliate at apex, 
7 to 11 mm. long; achenes oblong-obovate, flattish, densely pilose, subglabrate below,
