MAT IALS TOWARD A MONOGRAPH OF THE GENUS LIPPIA. IX Harold N. Moldenke LIPPIA TAYACAJANA Moldenke Additional bibliographg: Moldenke, Phytologia 12: 506. 1966. Shrub, about 1 m. tall; branches slender, tetragonal, ribbed, densely short-pubescent when young, glabrescent in age and then with peeling shreddy bark, brown, somewhat twiggy below; triga very short, leafy; nodes not annulate; principal internodes auch abbreviated, 1-3 cm. long leaves decussate-opposite; petioles slender, 1-2 mn. long and densely short-pubescent or obsolete; leaf-blades firsly chartaceous, uniformly gray-green on both sur-faces, oblanceolate-elliptic, 0.8-1.9 cm. long, 3-9 m. wide, rounded or acute at the apex, cuneate-attenuate at the base, re-volute along the margins and serrate from about the middle to the apex, scabrous and substrigose above, densely tomentellous beneath; midrib and the slender secondaries deeply impressed above, very proBinent beneath; inflorescence axLllary, solitary in each axil, 1-1.5 cm. long, capitate, rather few-or suhaz-flowered; peduncles very slender or filiform, 10-12 mm. long, densely ap-pressed-pubescent with antrorse canescent or yellowish hairs; heads amall, about 5 m. long and wide; bractleta lanceolate, a-bout ma. long0 and 1.5 mr. vide, sharply acute at the apex, densely appressed-strigose-pubescent; corolla hypocrateriform, white, about 5 m. long, its limb about 2 m. wide. The type of this species was collected by August Weberbauer (no. 6510) in the valley of the Mantaro, northeast of Papaas, in the province of Tayacaja, Huancavelica, Peru, at an altitude of 1800--1900 meters, in March, 1913, and sl deposited in the United States National Herbarim at Washington. The species is obviously closely related to L. ferruginea H.B.K. It has been found growing on dry slopes at an altitude of 1450 to 1900 meters, flowering in March and June. A vernacular name recorded for it is "limoncillo". The Asher, Kates, & Cia. 17987, cited below, is placed hore ten-tativelybecause of is fragentary nature. In all, h herbarium specimens, including the type, and 2 mountedphotographs have been examined by me.
