Description

2b. Cojoba arborea var. cubensis (Bisse) Barneby & Grimes, comb, et stat. nov. Pithecellobium cubense Bisse, Ciencias (Cuba), Bot. 2: 7. 1975. — "Cuba, Pinar del Río; Vinales: . . . km 16,5 de la carretera Vinales-Pinar del Río ... Nr. 541, 1966 nov. 27, leg: J. Bisse." — Holotypus, HAJB n.v.; isotypus, JE 000541!. — Twelve paratypi, all collected by Bisse & al., are cited, but none of the numerous examples assembled by C. Wright, Britton and collaborators, or Bro. León.

Pithecellobium arboreum sensu auct. recentior., maxima ex parte quoad floras cubensem et hispaniolanam; non var. arborea sens. str.

Like var. arborea except in lesser stature, rarely over 15 m, and in characters of foliage, usually shorter androecial tube, smaller seeds, as given in key to varieties; lf-stk of larger lvs ±2-9 cm.

In seasonally dry woodland and along streams, 5-850 m, widespread and common in Cuba, from Pinar del Río to Oriente; on Hispaniola recorded from Haiti only from dept. Nord-Ouest, in Domincan Republic scattered across the N and E departments.-Map 14. — Fl. I-VI, randomly in other months. — Abey, calo moruro.

The var. cubensis, well known to Britton in the field, was not distinguished by him from typical C. arborea, which he had collected frequently in Puerto Rico and Jamaica. It seems to represent an ecotype prevalent in woodland drier (at least during part of the year) than that normally tolerated by var. arborea.
