Keys to genera, species, and varieties, or acute, penicillate, papillose, or glabrous. Achenes descriptions, and illustrations are provided for Ar- columnar, turbinate, or fusiform, ribbed to costate naldoa (3 spp.), Barnadesia (\3 spp.), Chaetanthe- or smooth, sericeous, glandular, or glabrous; pap- ra (4 spp.), Chaptalia (10 spp.), Chucoa (1 sp.), pus of bristles, usually 1-2-seriate, scabrid, bar- Chuquiraga (5 spp.), Dasyphyllum (8 spp.), Ful- bellate, or plumose, or occasionally scalelike, flat- caldea (1 sp.), Gerbera (1 sp.), Gochnatia (4 spp.), tened, or setaceous, glabrous to hirtellous. Jungia (10 spp.), Leucheria (1 sp.), Lycoseris (2 spp.), Mutisia ( 1 5 spp.), Onoseris (18 spp.), Perezia Mutisieae (sensu latd) contains 89 genera with (7 spp.), Plazia (2 spp.), Polyachyrus (3 spp.), over 975 recorded species in tropical and sub- Proustia (5 spp.), Trichocline (2 spp.), and Trixis tropical America, Africa, Asia, Australia, and Ha- (6 spp.). The generic limits of Proustia are here waii (Cabrera, 1977). It is predominantly a Neo- expanded to include species previously accepted tropical tribe with greatest generic representation in Lophopappus and require the following new in South America, where no fewer than 65 of its combinations: P. berberidifolia (Cabr.) Ferreyra, genera occur. The tribe contains endemic genera P. foliosa (Rusby) Ferreyra, and P. peruviana in several other areas for example, North Amer- (Cabr.) Ferreyra. Lectotypification is provided for ica (5 genera), Asia (5 genera), Australia ( 1 genus), Dasyphyllum ferox (Wedd.) Cabr. and Plazia Africa (10 genera), and several Pacific Islands (1 daphnoides Wedd. genus). Western South America is a center of high generic diversity; the Andean Cordillera contains over 30 genera with distributions generally above 2000 m. Peru is particularly rich with 21 genera Tribe MUTISIEAE and over 120 species distributed in various eco- systems of the Coast, Sierra, and Selva. Species Mutisieae Cass., J. Phys. Chem. Hist. Nat.

Fewer than six species are Annual or perennial herbs, lianas, shrubs, or found in the more humid tropics of the Amazon small trees.

Capitu- la, Chaptalia nutans, Lycoseris spp., Trixis divar- lescences of solitary heads, sessile, pedunculate, or icatd). Gerbera is predominantly an Asian and Af- scapose, or several-headed panicles or cymes, oc- rican genus, with only one species cultivated in casionally glomerulate in pseudocephalia or syn- Peru. Diversity within genera is also variable; the florescences. Capitula homogamous, discoid, or monotypic genus Chucoa is endemic to a single heterogamous, radiate to disciform; involucres valley in northern Peru, whereas Onoseris and globose to cylindric; receptacles flat or convex, Trixis each occur in both hemispheres from the naked (paleate in Jungia, Arnaldod), foveolate, or United States to the Patagonian region of Argen- hispid-fimbrillate
