Drosera heterophylla from Australia Sondera (Lindley) dry from Kew
Leaves peltate, forming apparently forming a rather flattened cup, the two sides not being quite equal & regular, as I suppose is implied by the name
Marginal tentacles long, & even those on the disc rather longer than usual. The glands evidently secrete much viscid matter. I can see no spiral vessels in pedicels & the elongated cells are marked with lines crossing each other diagonally; therefore as far as leaves are concerned it seems to derve deserve generic rank
(Some of the vessels [united] of by spiral are barred & dotted).
Leaves very small— no insect in the 3 examined, but from viscid. s. impossible to doubt that it catches.
