|discussion=<p>The greatly reduced herbage of <i>Platanthera brevifolia</i> is distinctive. Robust plants may lack developed leaves altogether, with merely a few reduced bracts at the base of the stem and an inflorescence comprising nearly the entire height of the plant. A strong mycotrophic mode is suggested by the occurrence in some colonies of truly albino plants without pigmentation.</p><!--
--><p><i>Platanthera brevifolia</i> largely replaces <i>P. sparsiflora</i> in Mexico and is very distinctive at its northern limit in the United States. Although <i>P. sparsiflora</i> is exceedingly variable in floral dimensions, in habit, and in the number, size, and placement of leaves, the pattern seen in <i>P. brevifolia</i> seems to lie outside this range of variation. With a generally longer spur and very different ecologic requirements, it is here treated at the specific level. Nonetheless, <i>P. brevifolia</i> is reported to intergrade with <i>P. sparsiflora</i> in Mexico (R. McVaugh and W. R. Anderson. 1974+, vol. 16, pp. 254–256), yet the latter species probably does not range there beyond a possible occurrence in Baja California (M. A. Soto 1988).</p>
