A picture of the plant and inflorescence of Dimorphorchis rossii: The long
sparse rope of flowers left of center. This genus has only two species in
it; Dim. lowii and Dim rossii. Both species have two different forms of
complete flowers on a single inflorescence. In Dim rossii the first three
flowers are solid orange and very fragrant and the remaining flowers are
yellowish with spots and non-fragrant. Both forms have pollen and stigmatic
openings indicating to me that they are both fertile both ways, but I do not
know. I pollinated a yellow to orange and there appears to be some capsule
development. I pollinated an orange to a yellow and do not yet see evidence
of capsule development.

(The giant basket of plant hanging in the background with the short spike of
orange flowers is Lueddemannia pescatorei. Very short spike this year,
about 12 inches. It can produce a rope of orange flowers about 3 feet long
and even longer, but it is very overgrown in that basket and needs help. I
have never succeeded in getting this plant to produce seed.)
