Dear sundew-lovers,
A new species of Drosera has been described from the Guayana Highlands of Guyana, the article just arrived today:
Fleischmann, A., Wistuba, A. & McPherson, S.: Drosera solaris (Droseraceae), a new sundew from the Guayana Highlands. Willdenowia 32(2), pages 551-555.
The online-version of this paper is still requires a password for download, but I will obtain the copyrights to put it on a seperate homepage for free download within the next days. Of corse, I'll give you the link here then
.
It's a montane species from a small, tepui-like hill in the Guayana Highlands of Guyana, at the border to Brazil and close to Venezuela. The plant forms branched stems, has long multi-branched stipules and scentened white flowers on very short scapes (the flowers appear almost sessile, nested within the rosette of the plant) and thus is a little reminiscent of D. meristocaulis. Nevertheless, it isn't related to this strange plant at all, but it's a close relative of D. felix and D. kaieteurensis. Like Fernando already discovered for those two species, D. solaris as a unique way of seed dispersal: the seed is not shed from the capsule by wind as in most other Drosera species, but splashed away by rain drops from an open, cup-like capsule (so-called "splash-cup seed dispersal").
Habit of the plant.
Close-up of two ripe capsules.
Both of these wonderful photographs have been taken by Stewart McPherson and are used with kind permission.
All the best,
Andreas
