Habranthus ID assistance

[TimC]

I purchased this (presumed) habranthus sight-unseen, thinking that I might be getting H. caeruleus.  However, when it bloomed, it did not have the green throat pictured by PBS, but a dark red-purple throat.  Blooms appear before leaves.  When the leaves do appear, they are thin, almost appearing tubular, and eventually grow longer than the bloom stalk.  Flowers show a bluish tinge from the time they open, particularly in veins and outside tips, although the overall color is pale lavender/pink. Coloration is similar to lycoris sprengeri, although less pronounced.  The plant is small (a picture with H. robustus is included for comparison), about the height of H. tubispathus var texensis, although the flower is somewhat larger.

Suggestions as to ID, or for keys that might be helpful, would be appreciated.
