摘要

对秘鲁安第斯山脉中部千里光属的一个新种S.carhuanishoensis H.Beltrán&J.Calvo sp.nov.进行了描述和说明，该新种仅在拉劳斯区（Yauyos，Lima）已知。它是一种长满车辙的、乳白色的植物，茎紧贴在岩石上。其特征是其覆盖茎、叶和总苞的灰色lanate毛被，叶倒披针形至长圆形，短梗，顶生，单生，盘状头状，在小花的喉部和管之间显示短腺毛。它严格生长在石灰岩缝隙中。并将其形态与埃瓦氏S.evacoides Sch.Bip和伊什凯维卡氏S.ishcaivilcanus Cuatrec进行了比较。

Senecio carhuanishoensis H.Beltrán & J.Calvo sp. nov. (Asteraceae, Senecioneae), a new species from central Peru

A new species of Senecio L. from the central Andes of Peru, S. carhuanishoensis H.Beltrán & J.Calvo sp. nov., only known from the Laraos District (Yauyos, Lima), is described and illustrated. It is a suffrutescent, rupicolous plant with the stems rather appressed to the rocks. It is characterized by its greyish-lanate indumentum covering the stem, leaves, and involucre, by having leaves oblanceolate to oblong, short-pedunculate, terminal, solitary, discoid capitula, and by displaying short glandular trichomes between the throat and the tube of the florets. It strictly grows in limestone rock crevices. Its morphology is compared with those of S. evacoides Sch.Bip. and S. ishcaivilcanus Cuatrec.
