The larger, showier and better-known species, Rhyncholaelia digbyana, has been crossed with cattleyas to -- CHUCK McCARTNEY pass on its huge, frilly lip and large flower size to such handsome hybrids as Brassocattleya Mount Hood and Brassolaeliocattleya Pamela Hetherington (both now placed in the hybrid genus Rhyncholaeliocattleya due to the recent realignment of genera within the subfamily Laeliinae). The plants of the two Rhyncholaelia species look somewhat like thick-leaved unifoliate cattleyas, quite different from the pencil-like terete leaves of true brassavolas such as the familiar Brassavola nodosa. Both rhyncholaelias are thought to be pollinated by large night-flying moths because the ivory-white to light greenish flowers make them more visible in the dark and they produce strong, sweet nocturnal fragrances that are a good long-distance ::u'" ;/SRh.,.,oldtlia di,l>yall<J.
