Note
|
This species keys to the neighborhood of 0. discolor Klotzsch in Knuth 's recent revision of the genus. The latter, however, is distinguished from 0. chiriquensis by its larger bulbs with narrower scales, its leaves which are proportionally more nearly cordate and more densely pubescent beneath, and its glabrous style, in addition to other characters. Oxalis discolor is at present known only from southern Mexico. Oxalis valli- cola Rose, another Mexican species evidently closely related to 0. chiriquensis, is distinguishable from it by means of its multi- costate bulb scales, shorter corolla in proportion to the calyx, and smaller leaves which are conspicuously heavier in texture.
