Can anyone tell me where Cisanthe grandiflora sits, taxonomically
speaking. I've found mention of it in various horticultural contexts,
but no indication to which branch of the angiosperms it belongs.

From observation, it's a eudicot, with 5, free, petals, 5, free, sepals,
and a superior ovary. Presumably not an asterid, so either a rosid or a
basal eudicot.

A quick look shows that it does not exist

Occam's typorazor suggests you look at
Cistanthe grandiflora (Portulaceae, with characters as described by you)

Although it is known by that name in the trade, I suspect that is not its
correct name. MB3Tropicos never heard of it; neither did GardenWeb. I tried
IPNI, but it was broken. Judging from the picture of a flower I saw & your
description, it is rather primitive & close to the Tiliaceae. Some of the large
plant encyclopedias tell you which family each plant belongs to.

You are welcome

This would be a likely typo since Latin "cis-" is so common ("Gallia
cisalpina", also in organic chemistry) while 'cist-' (either from the genus
'Cistus' or from the Greek 'kiste': cf Eng 'cyst') is fairly uncommon
(Cistanthe, Cistanthera).
