Request for Species Id DKV 17062011-1:
Mhow, Dist Indore, Madhya Pradesh Seen on the roadside. The flowers are very much like that of the besharam (Ipomoea carnea) but the leaves are thicker and of a different shape. It is Cryptostegia grandiflora from family Apocynaceae Yes Cryptostegia grandiflora, and unlike Ipomoea carnea it is a woody climber. Beautiful flowers, no doubt… BUT…. ANOTHER FOUL WEED… Originally from Madagascar, was most likely imported because of its beautiful flowers… escaped from gardens, and is now a weed of horrific importance.. Its seedpods are prolific, producing up to 800+ seeds each, they fly off when pods open, remain viable for up to a year, germinate in moist soil, riverbanks in two weeks, in areas with at least 400mm rain, smothers native plants and kills stands of short trees,(there is one photo from australia…
showing the ghost trees covered with vines..at this link: http://www.weeds.org.au/rubber_vine_mgt_guide.pdf) MY question… since you saw and photographed it from the roadside… was this plant part of a stand of these? has agro-forestry department in Maharashtra or Madhya pradesh started looking at this weed?
Flowering Plant | 20May2011AR01 from Bangalore: I too think that this is Cryptostegia grandiflora Roxb. ex R.Br. of Apocynaceae family.
