Abstract: Changes in
succulent Cynanchum species are needed for the Flora of Somalia account of
Apocynaceae subfamily Asclepiadoideae. The
following changes are proposed within the tribe Asclepiadeae, subtribe Cynanchinae. Cynanchum viminale subsp. crassicaule,
another subspecific taxon in the C. viminale complex, is described as new based on
morphological, ecological and molecular evidence. Its chromosome number is specified with
2n=22. The new combination Cynanchum
viminale subsp. stipitaceum is proposed and Sarcostemma
andongense Hiern is recognized as a new synonym to C. viminale subsp. stipitaceum. |
