Mystery Iridaceae from the former Transvaal, SA

Dear group,

I am hoping someone can help me identify a species of Iridaceae I have
sighted growing on the Magaliesberg Mountains in the former Transvaal
province of South Africa (now Gauteng).

Unfortunately I do not have a photo, but I hope my description will be
sufficient to at least point me to the right genus.

The plants were growing on a north facing slope, in crevices on a rock sheet
which has some water seepage after rains. The plants were in flower during
January (mid summer) and seeds where ripe by April. The flowers were
approximately 2 cm in diameter and of a lilac-blue colour. The most striking
feature was the multiple branched inflorescences which were about 30 cm tall
and were in flower for 2-3 weeks.

I can not recall how the leaves looked, but they were not longer than the
inflorescence at time of flowering. There was a whole colony of them and not
just a few scattered individuals.

My first thought was Moraea, but I can't find anything similar in, The
Moraea's of Southern Africa, by Goldblatt.

Any help, advice, suggestions etc. are most welcome!
