Stapelianthus keraudreniae

Another species of Stapelianthus from Betioky district in south western Madagascar. This species is different from other Stapelianthus due to the raise annulus resembling some species of Huernia like H. zebrina. Also, the annulus appears to be viscid or sticky in the absence of dew.  During watering, I took care to avoid wetting the flowers. However, it is only strong enough to trap dirt as i did not see any dead ants or other insect stuck on it.  The flowers of Stapelianthus are quite diverse, tubular in S. decaryii , raise annulus in S. keraudreniae, recurved in S. insignis and open standard in S. hardyi, S. madagascariensis etc; more so than other genera of Stapeliaceae (Huernia, Stapelia).  I hope to find others like S. calcarophilus, S. madagascarensis.  Being a sub-tropical stapeliad, it adapts well under tropical conditions.
