Default Another African root parasite

Phil, I've not been able to get back to the links to the original
photos, so I've re-posted them. they may be seen at:

and

Are these what you were seeing?

Phil, I wonder if the link has gotten changed? (I can't get there --
it says the post has expired) The photos of Hyobanche sanguinea in
"Namaqualand South African Wild Flower Guide 1" are virtually identical
to mine. I'm quite sure Mel is right.

As for Sarcocaulon -- a stapeliad? I thought it was Geraniaceae?

They look like typical seed pods/fruits of a Stapeliad. Its the right
provenance and could be a Sarcocaulon. Definitely isn't Hyobanche or
Scrophulariaceae and I doubt very much if it's parasitic.

Thanks again, Mel Turner, for identifying my Thonningia sanguinea.


Here's another puzzler -- found in the Springbok area of
Namaqualand, South Africa. I'm thinking perhaps Cytinus sanguineus,
in Cytinaceae, but can find only photos of pistillate flowers, and
these are staminate. Descriptions do say the "staminal column sticks
out of the flower." But I'm guessing here.

Anyone know for sure? thanks.


I don't know for sure, but I get an impression of a "scroph"-like
tubular corolla in your photograph.

Perhaps it's Hyobanche sanguinea? [botanists seem fond of naming
red-flowered S. African parasites "sanguinea" and "sanguineus"]

This looks pretty similar to yours:
