"Stem stoloniferous, not swollen at base.  Flowers numerous in a fascicle, the bracts not bright red, spike of great size and pendant, height 2 m. or more.   Normally seminiferous species, with very small, fingerlike or slightly swollen, indedible fruits, usually white or green bracts, which may be partially persistent, simple scales, and pistil in terminal flowers distinctly shorter than the stamens, trunks usually slender.  Scale rarely two-thirds as long as perigonium, usually less acute, but with distinct apical shoulders.  Bracts all freely deciduous, fruits subcylindric."

Musa errans (M. Blanco) N. G. Teodoro from Quisumbing:

"Stem stoloniferous, not swollen at the base.  Flowers numerous in fascicle, bracts not bright red, or lilac, spadix large and pendant.   Plants 2 or more meters high.  Fruits inedible, with numerous seds, trunk usually slender, pistil in terminal flowers distinctly shorter than the stamens.   Scale nearly 2/3 as long as perigonium or less, tip usually acute, with distinct apical shoulder.  Fruits sub-cylindric, smooth, or slightly angular, bracts deciduous, greenish-red-yellow."

Blanco first applied the epithet "errans" in the combination M. troglodytarum errans which referred specifically to the plant now known as the Philippines form of M. acuminata, i.e. M. acuminata var. errans.  Teodoro's M. errans is rather confusing.  I have not yet seed Teodoro 1915 and Valmayor et al 2002 are vague on this point but it seems as if Teodoro listed only M. errans var. botoan.  In other words he seems to have "forgotten" to mention M. errans or, in context, M. errans var. errans as distinct from var. botoan.  Use of the term "botoan" implies that this is what we now know as M. balbisiana ("botohan" or "buthan" in the Philippines vernacular) but Valmayor et al 2002 suggest that Teodoro may by default also have included the other common wild banana of the Philippines in this entity, the plant we now know as M.acuminata var. errans.    Gerda Rossel's descriptions on the other hand are more suggestive of M. acuminata than M. balbisiana.  Quisumbing clarified the position somewhat listing i) M. errans (again effectively but not explicitly creating M. errans var. errans (= M. acuminata var. errans) ii) M. errans var. botoan (= M. balbisiana) and iii) M. errans var. basilisae, an entity with no known modern equivalent.

Uphof mentions various uses for the plant in the Philippines.  Young flowerheads are eaten as a cooked vegetable or raw.  Ripe fruits are fermented to make vinegar.  Young leaves are used as a poultice to treat chest ailments.  Juice from the base of the plant is used as a urethral injection to treat gonorrhoea.
