Mystery bulbous plant

Dear Gianni
I too have one of those and it has never flowered although the bulb has multiplied most satisfactorily.  I guess I might have bought it from Kirstenbosch Botanical Garden in Cape Town many years ago.  It is evergreen and lives indoors here in London in my conservatory, so very hot in summer and heated in winter.  Almost definitely Cyrtanthus obliquus or C. herrei.  But which one? And how to treat it?  The trouble is that one grows in winter and the other in summer, ie a different watering regime.
It would be great if any of you marvellously clever PBS people could offer a clue as to how to tell them apart and how to encourage flowering.
