Found in Alta Verapaz department of Guatemala at elevations around 800 meters as a large sized, warm growing, climbing epiphyte with stems with many internodes carrying thin, membraneous, ellliptic, obtuse, sessile base leaves that blooms in the summer on a several inflorescence.

Similar to V inodora but the new species differs in the flower smaller (up to 1.48" [3.7 cm] long vs. 1.8 to 2" [4.5-5 cm]), sepals and petals flat (vs. twisted), dorsal sepal elliptic (vs. linear lanceolate), lateral sepals much wider, strongly veined (vs. almost not veined), petals rounded at the apex (vs. subobtuse), lip slightly trilobed (vs. deeply trilobed) with shorter lateral lobes, midlobe apically rounded (vs. sub-acute), ovary somewhat curved geniculate in the upper part (vs. straight), fruit shorter (Fig. 4 & 5). Moreover, Vanilla rebecae is know hitherto only from Alta Verapaz in the center of the country whereas Vanilla inodora is present, in Guatemala, in the departments of the southern coast."
