SUMMARY:
The page distinguishes P. sikkimensis from P. Hopeana by calyx features and notes that P. Hopeana here has a pinkish to red tube, possibly approaching P. Waltoni. It also mentions chasmophila and references P. umbratilis? with number 33014.
CONTENT:
Here P. sikkimensis No , is very much mixed up with
P. Hopeana. But they are distinct, as can be seen from the calyx.
P. Hopeana here shows a pinkish tube, sometimes quite red, which
I suppose goes nearer to P. Waltoni. But I have seen no P. Hopeana
here, where the corolla is red tinted.
