acute to acuminate or rarely obtusish, at base cuneate to rounded- 
cuneate, barely petioled, 3-nerved, beneath reticulate, above green, 
somewhat lucid, densely and very harshly tuberculate-setose with 
short curved ascending bristles, beneath slightly paler, rather 
densely hispid-pilosulous with spreading scarcely rough hairs with- 
out tuberculate bases, entire or with about 6 pairs of distant 
sub-spreading teeth, 4-10 em. long, 1—2.5 cm. wide; petioles tuber- 
culate-setulose, 1.5-3 mm. long. Heads in subsessile cymes of 3-5 
at ends of branches, 1.7 em. wide; peduncle 3-10 mm. long, the 
pedicels equalling it or shorter; disk 10-11 mm. high, 12-13 mm. 
thick. Involucre 4—5-seriate, graduated, 8-9 mm. high, the 
phyllaries appressed, lanceolate, acuminate, somewhat thickened, 
densely and finely tuberculate, along margin and elevated midrib 
setose-hispidulous. Rays about 8, 6-7 mm. long, 3-5.5 mm. wide; 
disk-corollas hispidulous below, 5 mm. long (tube 1 mm.). Pales 
acuminate, mucronulate, tuberculate-hispidulous above, 8.5—9 mm. 
long. Achenes (immature) of disk sericeous, 4 mm. long; of ray 
3-gonous, ciliate-edged, sterile. Pappus of disk-achenes of 2 awns 
(3 mm. long) and about 8 linear-lanceolate free ciliate squamellae 
(1 mm. long); of ray-achenes of 3 very unequal paleaceous aristae.

MEXICO: Sierra Madre of northwestern Mexico, Seemann 2005 
(TYPE COLL.: G., K.).— Gray’s reference of this species to Oyedaea 
was evidently based on achenes belonging to a species of that genus 
which had in some manner found their way into the pocket 
mounted with the specimen of Seemann 2005 in the Gray Herba- 
rium, where they may still be seen. The species, however, is a true 
Viguzera, closely related to V. Pringlei, and in no way connected 
with Oyedaea. 
J 33. V. Parkinsonii (Hemsl.), comb. nov. Stoutish herbaceous 
perennial from a thick woody root bearing many fibrous rootlets, 
the stem simple, bearing 3-5 axillary and terminal heads above, 
below densely and harshly spreading-hispid-pilose and tuberculate- 
puberulous, above more sparsely strigose and strigillose. Leaves 
mostly alternate, crowded or rarely subremote, oblong to oval or 
oblong-lanceolate, sessile, strongly 3-nerved and venose, appressed- 
serrulate to subentire, dull green both sides and harshly tubercu- 
late-hispid-pilose with subspreading hairs, 4.5-12 em. long, 1.5-3.3
