Tribe MUTISIEAE Mutisieae Cass., J. Phys. Chem. Hist. Nat. Arts 88: 199. 1819. TYPE: Mutisia L. fil. Annual or perennial herbs, lianas, shrubs, or small trees. Leaves alternate and cauline, or con- fined to a basal rosette, rarely opposite. Capitu- lescences of solitary heads, sessile, pedunculate, or scapose, or several-headed panicles or cymes, oc- casionally glomerulate in pseudocephalia or syn- florescences. Capitula homogamous, discoid, or heterogamous, radiate to disciform; involucres globose to cylindric; receptacles flat or convex, naked (paleate in Jungia, Arnaldod), foveolate, or hispid-fimbrillate or glandular pubescent; phylla- ries (l-)2-12(-14)-seriate, usually unequal, usu- ally imbricate; florets iso-, di-, or trimorphic, the corollas bilabiate, the outer lip ligulate, 3-4-lobed to 3 4-dentate, the interior lip single or of 2 fused or unfused lobes; or actinomorphic, tubular, the limb 5-lobed, the lobes equal to subequal; anthers with truncate to pointed terminal appendage, the bases usually caudate with long tails (ecaudate in Barnadesia), the tails sometimes fringed at the tips; style branches short, truncate or obtuse to rounded or acute, penicillate, papillose, or glabrous. Achenes columnar, turbinate, or fusiform, ribbed to costate or smooth, sericeous, glandular, or glabrous; pap- pus of bristles, usually 1-2-seriate, scabrid, bar- bellate, or plumose, or occasionally scalelike, flat- tened, or setaceous, glabrous to hirtellous. Mutisieae (sensu latd) contains 89 genera with over 975 recorded species in tropical and sub- tropical America, Africa, Asia, Australia, and Ha- waii (Cabrera, 1977). It is predominantly a Neo- tropical tribe with greatest generic representation in South America, where no fewer than 65 of its genera occur. The tribe contains endemic genera in several other areas for example, North Amer- ica (5 genera), Asia (5 genera), Australia ( 1 genus), Africa (10 genera), and several Pacific Islands (1 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 and over 120 species distributed in various eco- systems of the Coast, Sierra, and Selva. Species diversity and distribution patterns are quite vari- able; intermontane valleys and the ceja de la mon- tana are richest in taxa. Fewer than six species are found in the more humid tropics of the Amazon basin of eastern Peru (e.g., Barnadesia caryophyl- la, Chaptalia nutans, Lycoseris spp., Trixis divar- icatd). Gerbera is predominantly an Asian and Af- rican genus, with only one species cultivated in Peru. Diversity within genera is also variable; the monotypic genus Chucoa is endemic to a single valley in northern Peru, whereas Onoseris and Trixis each occur in both hemispheres from the United States to the Patagonian region of Argen- tina and Chile. Some pairs of genera and species exhibit overall morphological convergence. Ful- caldea and Barnadesia, Chuquiraga and Dasy- phyllum, and even Chuquiraga spinosa and Chu- quiraga johnstonii are quite similar as herbarium specimens but easily distinguishable in the field. The color of the corolla is an important character, FIELDIANA: BOTANY, N.S., NO. 35, MAY 31, 1995, PP. 1-101 particularly within species with close resem- blancefor example, both Mutisia pulcherrima and M. wurdackii are quite similar lianas, but the former has orange corollas and the latter red.

TYPE: Arnaldoa magnifica Cabr. = Arnaldoa weberbaueri (Muschl.) Ferreyra Shrubs to 5 m tall, much-branched, the branch- es usually spiny at least below, the nodal spines geminate, divergent, fuscous. Leaves alternate, petiolate; blades oblong- to ovate-elliptic, coria- ceous, the abaxial surfaces with midrib prominent, penninerved with 2-3 pairs of secondary veins, the margins entire. Capitulescences of solitary, ter- minal heads. Capitula homogamous, discoid, ses- sile; involucres broadly campanulate; receptacles plane, paleate, the pales yellowish; phyllaries 1 0- 13-seriate, acuminate; florets isomorphic, her- maphroditic, the corollas orange or red, bilabiate, the outer lip liguliform, 5-nerved, apically 4-lobed, the inner lip filiform; anthers sagittate; styles cy- lindric, 30-32 mm long, the branches small, api- cally acute. Achenes turbinate or cylindric; pappus of plumose bristles, yellowish. Arnaldoa consists of three species, all confined to central and northern Peru. The genus is most easily recognized by its large, homogamous capit- ula with zygomorphic corollas. It shares relation- ships with the other members of the subtribe Bar- nadesiinae, including Barnadesia, Chuquiraga, and Dasyphyllum. References CABRERA, A. L. 1962. Compuestas Andinas Nuevas. Bol.

Barnadesia corymbosa is distinguished by its ar- borescent habit, predominately spineless branch- es, petiolate leaves, and multiheaded corymbose capitulescences. This species superficially resem- bles B. parviflora of Ecuador and Colombia but is easily distinguished by its fused staminal fila- ments. Cabrera (1960, p. 209) determined that Barnadesia venosa was conspecific with B. cor- ymbosa, and I agree with that placement. CAJAMARCA. Jaen: Colasay, W oytkowski 6955 (MO). CUSCO.

FAMILY ASTERACEAE. VI. 19 uted from the United States to southern South America, with 1 here treated for Peru. There has been considerable taxonomic disagreement as to the generic limits among Chaptalia, Gerbera, and Trichocline (Burkart, 1944; Zardini, 1974; Han- sen, 1 990). The three are separated with some dif- ficulty and various species have been moved among these genera. Chaptalia is characterized by tri- morphic florets (rarely strictly dimorphic), ray flo- rets with corollas merely equalling or slightly sur- passing the phyllaries, staminodia absent, and ros- trate achenes with inflated trichomes or, more commonly, glabrous. Gerbera possesses stamino- dia in the ray florets and achenes with slender, acute trichomes; Trichocline also possesses ray flo- rets with staminodia and achenes with slightly in- flated, myxogenic trichomes mixed with capitate- glandular types. Burkart (1944) provided a dis- Key to Peruvian Species of Chaptalia cussion of the characters separating Chaptalia from its close relatives and provided a key to putative sections of the genus. The treatment presented here should be considered provisional; the Andean spe- cies of the genus are in need of monographic treat- ment. References BURKART, A. 1944.

Chaptalia rotundifolia most closely resembles C. cordata and is rather arbitrarily distinguished from that species by its rotund to ovate, noncor- date leaf blades and larger involucres. Detailed populational studies are needed, especially in northern Peru, where the two species are appar- ently sympatric. FIELDIANA: BOTANY Hieronymus (1905) described C. cordata var. ferrugineo-tomentosa, calling attention to its densely ferrugineo-tomentose phyllaries. The type material from northern Peru is no longer available for study; however, a photograph of the type (FM neg. 1 6000 ex B) shows that Burkart examined the holotype collection in 1930 and annotated it as equaling C. rotundifolia. The photograph of C. ovalis (FM neg. 3807 1 ex p) and D. Don's descrip- tion both conform to material here placed under C. rotundifolia. ANCASH.

Chuquiraga consists of approximately 20 spe- cies largely confined to the Andean Cordillera from Colombia to Argentina and Chile. In Peru the ge- nus is represented by five species distributed in the jalca and puna formations at elevations above 3000 m. Chuquiraga is most similar to Arnaldoa and distinguished from that genus by possessing actinomorphic corollas with five lobes and sta- minal filaments inserted at the base of the corollas rather than above the base as in Arnaldoa. Chu- quiraga is readily separated from Dasyphyllum with the former possessing coriaceous leaves with only one central nerve, yellow to orange corollas, and anthers with linear-lanceolate, apical appendages. Various species of Chuquiraga are used in folk medicine and are commonly found in herb mar- kets. VI. CHUQUIRAGA Chuquiraga Juss., Gen. pi. 178. 1789. TYPE: Chu- quiraga jussieui J. F.

Achenes cylindric, densely villous :o glabrous; pappus of plumose bristles, 1 -seriate. Dasyphyllum consists of approximately 37 spe- :ies of shrubs or small trees restricted to South \merica from the Andean Cordillera of Colombia md Venezuela to eastern Brazil and central Chile. Die habit of Dasyphyllum is very close to Chu- juiraga; it can be distinguished from that genus, lowever, in having three- or five-nerved leaves, :he stamens united at the lower part of the tube )f the corolla, the anthers slightly sagittate with :he terminal appendage bifid or truncate, the flo- ets with white, pale violet, or yellowish corollas, md tricolpate pollen grains. It is readily distin- guished from Barnadesia, which possesses gener- ally reddish corollas, acute anther appendages, and lophate pollen. In addition, Dasyphyllum finds its greatest diversity in the subtropical region east of the Andean Cordillera, while Chuquiraga and Bar- nadesia find their greatest diversity within the Cor- dillera. Although Tovar (1953) recognized Flotovia as a distinct genus, Cabrera (1959) combined it with Dasyphyllum, and it is not accepted in the present treatment. References CABRERA, A. L. 1959.
