Remarks (internal):The Sydows (1924) determined that the host is Amphilophium and the spores are teliospores, not anamorph spores. They suggested that Hennings (1905) could have identified the material as Haplolophium (Bignoniaceae), but in fact it was registered as Haplophyllum (Rutaceae). Because of this host identification error they gave the rust a new specific epithet and placed it in Diorchidium because of the placement of the pedicel close to the septum. Cummins (1940) accepted this epithet on practical grounds and transferred it to Prospodium. The code requires that the original epithet be used.
Among short-cycle species of Prospodium on Bignoniaceae only P. haplophylli and P. perelegans have teliospores with mostly vertical septa (diorchidioid). P. perelegans has smaller teliospores, 27-33 µm long, compared to P. haplophylli, (33-)37-44 µm long.

Spermogonia amphigenous in small groups. Aecia and uredinia not produced. Telia mostly hypophyllous, associated with spermogonia along veins, cinnamon brown, pulverulent, without paraphyses; spores (33-)37-44 x (22-)24-27(-28) µm, mostly transversely oblong-ellipsoid (diorchidioid), constricted at septum; wall bilaminate, the outer layer 0.5-2 µm thick, but over pores 2.5-3.5(-4) µm, conspicuously echinulate, sharp cones spaced (2.5-)3-4(-5) µm, and inner wall 1.5-2.5 µm thick, pale chestnut brown or dark golden brown; pore terminal in each cell of diorchidioid spores, each with a low, hyaline umbo, pedicel hyaline, usually broken at a septum 6-10 µm below spore.
Specimen examined. - Peru: Loreto: Iquitos, Rio Amazonas, reported as on Haplophyllum sp. (Rutaceae), Apr 1903, E. Ule 3209 (holotype: B), (error for Amphilophium aschersonii Ule (Bignoniaceae) fide Sydow (1924). Not otherwise known; all names based on the same teleomorph type.
