Heliopsis suffruticosa (Compositae, Heliantheae), una nueva especie del occidente de Zacatecas
Heliopsis suffruticosa is described from the Sierra de Sombrerete, in western Zacatecas, Mexico, growing in pinyon woodland on limestone. It differs from other species in the genus in having suffruticose habit, narrowly lanceolate to linear leaves with entire to sparsely serrulated margin, and pedun...

| description | Heliopsis suffruticosa is described from the Sierra de Sombrerete, in western Zacatecas, Mexico, growing in pinyon woodland on limestone. It differs from other species in the genus in having suffruticose habit, narrowly lanceolate to linear leaves with entire to sparsely serrulated margin, and peduncles gradually enlarged towards the apex, a combination of characters shared with some species of Zinnia. A key to distinguish among the Mexican species of perennial Heliopsis is presented. As other Heliopsis species, H. suffruticosa roots contain alkamides, in this case five diacetylenic conjugated next to a group methyl in the omega position, isobutyl alkamides. |

It differs from other species in the genus in having suffruticose habit, narrowly lanceolate to linear leaves with entire to sparsely serrulated margin, and peduncles gradually enlarged towards the apex, a combination of characters shared with some species of Zinnia. A key to distinguish among the Mexican species of perennial Heliopsis is presented. As other Heliopsis species, H. suffruticosa roots contain alkamides, in this case five diacetylenic conjugated next to a group methyl in the omega position, isobutyl alkamides. Se describe Heliopsis suffruticosa de la Sierra de Sombrerete al occidente de Zacatecas, de bosque bajo abierto de piñonero sobre caliza. La especie difiere de otras del género por tener hábito sufruticoso, hojas angostamente lanceoladas a lineares, enteras a espaciadamente serruladas y pedúnculo gradualmente ensanchado hacia el ápice, características que comparte con algunas especies de Zinnia. Se presenta una clave para distinguir entre las especies mexicanas de hábito perenne de Heliopsis. Al igual que en otros representantes de este género, las raíces de H. suffruticosa presentan alcamidas, detectándose en este caso cinco isobutil alcamidas diacetilénicas conjugadas, unidas a un metilo terminal en posición omega.
