Two new taxa of Bursera (Burseraceae) of Baja California Sur, Mexico

We describe and illustrate two new taxa of Bursera from the Cape Region in the southern sector of the Baja California Peninsula, Mexico. One is named B. littoralis and the other B. rupicola. The former is morphologically related to B. filicifolia and B. laxiflora of the southern peninsula and still...

description We describe and illustrate two new taxa of Bursera from the Cape Region in the southern sector of the Baja California Peninsula, Mexico. One is named B. littoralis and the other B. rupicola. The former is morphologically related to B. filicifolia and B. laxiflora of the southern peninsula and still with B. ribana of western Mexico, but differs in its smaller leaves and leaflets, the shrubby habit with dense and intricate branching, and in its habitat on the coastal dunes. The second taxon is related to B. epinnata of the southern peninsula, differing from it in its almost always unifoliolate, shiny, and membranaceous leaves with scattered simple and glandular trichomes, short inflorescences with few flowers and particularly in its shrubby growth habit with pendent branches. Both species belong to the Bullockia section, having a bilocular ovary, bivalvate fruit, well developed cataphylls, 4(5)-merous flowers, and non-exfoliating bark.

Se describen e ilustran dos nuevos taxa del género Bursera de la región de Los Cabos, en el extremo meridional de la Península de Baja California, México. Uno de estos es designado como B. littoralis y el otro como B. rupicola. El primero tiene cierta similitud con B. filicifolia y B. laxiflora del sur de la península e incluso con B. ribana del occidente del país, pero difiere de éstas por el menor tamaño de las hojas y folíolos, tiene también un porte arbustivo con ramificación compacta e intrincada, y particularmente porque habita en la duna costera. El segundo taxon se relaciona con B. epinnata del sur de la península, distinguiéndose de ésta por presentar hojas casi siempre unifolioladas con folíolos membranáceos, brillantes, las inflorescencias cortas con menor número de flores, y particularmente por su hábito arbustivo de ramas colgantes. Ambas especies pertenecen a la sección Bullockia por tener el ovario 2-locular, fruto 2-valvado, catafilos manifiestos, flores 4(5)-meras y corteza no exfoliante.
