However, it differs from those species by the presence of stipels and basal callosities, and its shallowly crenate floral disk. <em>Millettia tomentos</em><em>a</em> is similar to <em>M. extensa</em> and <em>M. suddeei</em>, but differs from the first species by having a brachyblast bearing ca 10 flowers, the standard with basal callosities, presence of a tubular floral disk and oblong to slightly obovate fruits; and it differs from the latter by the absence of stipels, the standard with swollen basal callosities, monadelphous stamens and the tubular floral disc.
