"Habenaria minuticalcar resembles H. guilleminii in the size and morphology of the spur. However, it is distinguished by the linear, narrow, .8 to 1.2" [2 to 3 mm] wide leaves vs lanceolate or elliptical, .2 to .92" [5 to 23 mm] wide in H. guilleminii), narrow, .036 to .048" [.9 to 1.2 mm] wide lateral sepals vs .08 to .12" [2 to 3 mm wide], petal anterior segment .06 to .088" [1.5 to 2.2 mm] long, reaching half the size of the petal posterior segment vs reduced to a tooth-like projectio) and the lip lateral segments at most half the length of the median segment vs the lateral segments longer than the median segment."
