Sarukhan's Hesper Palm
Long believed to be nothing else than the common B. dulcis, this palm has only recently been described from its habitat occupying a small area on the border between the Mexican states of Nayarit and Jalisco, where it grows in dry tropical and pine-oak forest, high up in the mountains between 1100 and 1650 m (3600 and 5400 ft.). While similar to B. aculeata and B. pimo, with a moderate stature and a smallish crown of green fan leaves with lax tips, it can readily be separated from the two. Its fruits are much smaller than those of B. aculeata while being bigger than those of B. pimo and much larger than B. dulcis. With B. dulcis it shares the thick, densely furry branchlets of the inflorescence. While being a common component of the native vegetation within its range, it has remained exceedingly rare in cultivation. It can be expected to thrive under most temperate conditions and be hardy to considerable freezes.
