Acacia collinsii × hindsii
Creators
Description
Acacia collinsii x A. hindsii. These two species are sympatric in parts of their ranges and are sometimes found at the same sites on soils and in climates that are suitable for seasonal agriculture (Janzen, 1974). One sterile specimen was encountered that is intermediate between these two species. This specimen is similar to A. collinsii in having relatively large leaflets (7-11 mm long, 1.6-3.1 mm wide) with obvious secondary veins, and with less than 25 pairs of leaflets per pinna. It is similar to A. hindsii in that rachis glands are common at many of the pinnae nodes, the stipular spines are slightly flattened, and the petiolar glands are narrowly volcano-shaped. The rachis glands, for the most part, are broadly dome-shaped, typical of the petiolar glands of A. collinsii. Intermediate rachis and petiolar gland shapes also are common on this specimen and are slightly compressed volcano-shaped, but not as narrow as those of A. hindsii. The specimen is weakly cyanogenic, typical of many specimens of A. hindsii, but not of A. collinsii. Final determination of the status of this probable hybrid must await flowering and fruiting material (Ebinger & Seigler, 1992).
Representative specimen. MEXICO. Guerrero: Lok. 7, Mirador, 5 km S de la Base Naval de Icacos, Brimer s.n. (ILL).
