Drosera indumenta

D. indumenta (previously D. aff. macrantha Swamp Form) is one of the species in the macrantha complex consisting of D. eremaea, D. hirsuta, D. indumenta, D. macrantha and D. planchonii. It is a climbing species reaching 45 to 65 cm in length. The typical feature of this species is its glabrous, hairy stem from the base to the inflorescence. Like other species in this complex D. indumenta can use other plants as support by gluing one or more leaves tightly to them. The flowers are pink.
This species is usually found in swampland habitats, often growing in waterlogged conditions during winter, which may dry out during summer. However, I use the same conditions as for other macrantha complex species in culture, although those grow usually in well-drained habitats.

My plants produce daughter tubers occasionally, but far less than some D. macrantha forms.

The tubers of this species are white and often have wart-like structures on their surface.

A short summary of typical features within the macrantha complex:
D. eremaea: scattered minute glands on the stem, tuber white and smooth, seeds have a spear-like apex
D. hirsuta: glabrous stem, upper part densely hirsute (=covered with non-glandular hairs), tuber white and smooth, seeds have a wide, one-sided wing
D. indumenta: stem covered with hairs along its full length, tuber white and warty, seeds have a narrow one-sided wing
D. macrantha: lower stem section glabrous, upper section glandular, tuber white and warty, seeds have a wide, spear-like apex
D. planchonii: lower stem section glabrous, upper section sparsely glandular, tuber white and warty, seeds with a narrow, longitudinal, one-sided ledge a wide, paddle-like apex

Allen Lowrie offered this form as D. (aff.) macrantha Swamp Form in the past.



Emerging plants and stem sections Drosera indumenta has a stem densely covered with (mostly red) non-glandular hairs throughout its entire length.




The extent of colouration can be somewhat variable. All plants on these pictures grow under the same conditions in the same tray. The upper two pictures show a plant in an earlier development stage, the following three pictures a different clone which started to develop its leaves much earlier. Note the different intensity of the reddish colouration. All pictures were taken on the same day.


A close-up shows that the stem is covered with tentacle-like structures, not with hairs like e.g. D. hirsuta.
