The genus Viburnum in northwestern South America

E. P. KILLIP AND) A. C. SMITH

In attemnptingo i(lentifya large series of specimens of Vlibtr-numwhich we collected in eastern Colombia, we found that nearlyall the Andean material of this genus in American herbaria hadbeen referred to V. glabratumzH.B.K., though quite obviouslyseveral species were represented. Monographers apparently havepaild little attentionto the South American representativesof thegenus, confining hemselves almost wholly to the species occurring

in the North Temperate regions. Several Peruvian species wererecentlydescribedIby Graebner, but these appear to be local spe-cies which do not range into the northern part of the Andes.

As in the case of the species from North America and the OldWorld, the principal diagnostic characters lie in leaf-shape, inclu-ment, and size and branching of the corymbs, the flowers andIfruits showing little variation.

The herbaria in which specimens we have examined are de-

positecl are indicated thus: Arnold Arboretum (A) ; Field Mu-

seum of Natural History (F); Gray Herbarium of Harvard Uni-versity (G) ; Royal Botanic Gardens, Kew (K) ; U. S. NationalHerbarium (N) ; New York Botanical Garden (Y).

Perhaps more than a single species is represented by the ma-

terial here cited, but we have not been able to findreliable charac-

ters upon which separate species can be based. Apparently the

habit of the plants is quite variable. Lehmann's 51I61, the type of

V. Urbani, is said to be a liana-slhrubwith elongate branches.Viburnum pichinchensc is merely described as a shrub, 8 to 12

feet high, but the type specimen suggests a plant of rather laxhabit. The plants of Norte de Santander, which we place in the

followingsubspecies, were all compact shrubswith shortbranches.The Pennell & Killip specimen from southwestern Colombia

closely agrees with the type specimen from Mt. Pichincha. In

other material from that region the pubescence is less dense on

the under surface of the leaves, which are broader and more

noticeably denticulate. Pittier's 1356 has large persistentbracts

up to I.5 cm. long. Graebner referred Lehniann's 7oj0 to V.anabaptista, a Costa Rican species. A specimen of this, courte-

ously lent by the Director of the Royal Botanic Gardens, Kew,

agrees closely with other material here I)laced in V. pichinclhciisc.

2a. Viburnum pichinchense toledense subsp. nov. Compactshrub or small tree, 3-6 m. high, withlshort branches; leaves intwo's and three's, ovate or oblong-ovate, 4-7 cm. long, 2.5-5 cm.wide, very densely grayish- or rufo-tomentose below, strongly mn-pressed-nerved above; inflorescencetwice-branched,few-flowered.

Type, Killip & SEnith20589, collected March T2, 1927, on east-

ern slope of P'aramo del Hatico en route from Tole(lo to Pam-

plona, alt. 2800 m., Dept. Norte de Santan(ler, Colombia, and

deposited in the U. S. National Herbarium (no. 1,355,614). Dup-

licates at A, G, Y. Other specimens are: Norte de Sanltan(ler:Divide between Rio La Teja and Rio Mesme, 2800 m., Killip 5

This may be specifically distinct from V. pichlinlchllcsc n the

basis of its compact habit and smaller leaves, which are often

in three's.

By far the greater part of the Andean material of Viburnumnhas been referred to this species, apparently with little justifica-tion. The description of the indument of the type specimen as'tenuiter canescenti-pulverulentes' applies only to a small part ofthe specimens examined in connection with this revision, and in

Columbia true V. glabratum1?1pparently has only a limited range.The original description states that the plant has two or threebracts, similar to the leaves but smaller. In Pennell's no. I76oand Andre's K44,5 these bracts are present, but in the other ma-terial here cited theyare wanting, though quite possibly theymayhave been present at an earlier stage.

4. VIBURNUM TRIPHYfLLUM Benth. P1. Hartw. 189. 1845.Shrub or small tree; branchlets terete, hirsute with simple orusually stellate hairs or glabrescent; leaves often in tlhree's (es-pecially the upper ones), ovate or ovate-oblong, 4-8 cm. long, 2-5cm. wide, roun(led or acutish at apex and base, entire,thick-coria-ceous, lustrous, glabrous or usually hirsute-tomentose n the axilsof the nerves beneath, the nerves usually impressed above; pe-duncles stout, 3-6 cm. long; corymbs sometimes bracteate, 4-7(rarely to 9) cm. wide, 6-8-rayed, 2- or 3-times branched, therays rufo-hirtellous with simple or stellate hairs; calyx tubeI.6-I.8 mm. long, sparingly glandular-punctate, the lobes aboutI mm. long, subacute, ciliate; corolla about I.5 mm. in diameterat base, 3.7-4 mm. long, the lobes oblong, rounded, about 2.1 mnm.wide; fruitovoid.
