406 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
This species and the next are distinguished by their broadly ovate or oval phyllaries. 
In the present plant these are provided with abruptly narrowed tips which are 
wanting in F’. oolepis. 
19. Flourensia oolepis Blake, sp. nov. 
Branching shrub; branchlets densely resinous-granular, 1 or 2-headed; leaf blades 
5.5 to 8.5 cm. long, 2 to 3.2 cm. wide, elliptic-lanceolate or elliptic, acuminate at each 
end, entire or with a few acute teeth above, reticulate-venulose with about 12 pairs 
of lateral veins, resinous-granular and minutely puberulous with several-celled hairs 
chiefly along veins and veinlets; petioles about 1 cm. long, marginate above, resinous; 
peduncles resinous, minutely puberulous at apex, 4 to 6 cm. long; heads 3 to 3.5 cm. 
wide; disk 1 to 1.2 cm. high, 1.7 to 2.1 cm. thick; involucre 4-seriate, 7 to 8 mm. 
high, graduated, the outer phyllaries broadly ovate (5 to 5.5 mm. long, 2.5 to 4 mm. 
wide), the inner gradually more oblong, all more or less striate, acutish, mucronate, 
densely resinous-granular, ciliolate; rays 12 to 16, linear-oblong, 12 mm. long, 2.5 mm. 
wide; disk corollas sparsely resinous, 4.5 mm. long (tube 1 mm.); pales widened above, 
subtruncate and resinous at apex, strongly striatulate, 7 mm. long; achenes obovate, 
silky except toward margin, 5.5 to 6.5 mm. long; awns 2, strongly ampliate and deeply 
lacerate at base, 4 mm. long; true squamellae none. 
Type in the Berlin Herbarium, collected at Cuesta de la Oyada, Sierra Achala de 
Cordoba, Argentina, March 22, 1876, by G. Hieronymus. Photograph and fragments 
in the Gray Herbarium. 
ADDITIONAL SPECIMEN EXAMINED: 
ARGENTINA: Foot of the Cuesta de la Chacras, near Devisaderos, Taninga, etc., 
west side of the Sierra de Cérdoba, February 14, 1876, Hieronymus (Ber.). 
Flourensia oolepis is distinguished from its only near relative, F. tortuosa, by the 
acutish, not abruptly narrow-tipped, phyllaries. 
20. Flourensia leptopoda Blake, sp. nov. 
Branching shrub; younger branchlets purplish, resinous-granulose, the older ones 
brown; leaf blades 3 to 4.5 cm. long, 1.3 to 2.5 cm. wide, rhombic-ovate, acuminate, 
mucronate, cuneate at base, deeply and irregularly repand-dentate with 4 to 6 pairs 
of cuspidate teeth, lucid, reticulate-venose with about 10 pairs of lateral veins, 
glabrous or beneath resinous-granular and very slightly hispidulous; petioles slender, 
8 to 12 mm. long; heads 1.5 cm. wide, racemose-paniculate on 1 to 3-headed terminal 
and axillary peduncles; disk 8 mm. high, 8 mm. thick; involucre 2-seriate, 4 to 5 
mm. high, the phyllaries equal, lanceolate or lance-subulate, subobtuse, resinous- 
granular and very sparsely strigillose; rays oval, tridenticulate, 7 mm. long, 4.5mm. 
wide; disk corollas glabrous, 4.5 mm. long (tube 1.2 mm.); pales resinous, obtuse, 
5.5 mm. long; immature achenes silky, 3.5 mm. long; awns 2, ciliate, slightly flattened, 
3 mm. long; squamellae none. 
Type in the Berlin Herbarium, collected at Farrecillas (?), Province Rioja, Argen- 
tina, March 5, 1906, by J. 8. Urriche. Photograph and fragments in the Gray Her- 
barium. 
Readily distinguished by its deeply dentate rhombic-ovate leaves on long slender 
petioles. Like others of the same genus, this species bears the vernacular name 
“‘maravilla.’”’
