Trianthema cypseloides (Frenzl) Benth.

Hawkesbury Pigweed (Trianthema cypseloides)

This species is only known from the type material that was collected from the Hawkesbury River in New South Wales, Australia

This was a small, creeping, ground-dwelling herb with short branches and egg-shaped, about 0,5 cm long, slightly succulent leaves and flowers appearing in loose, flat-topped clusters.

The reasons for the extinction of this species are not known.

Lampranthus vanzijliae (L. Bolus) N. E. Br.

Worcester Brightfig (Lampranthus vanzijliae)

The Worcester Brightfig, described in 1930, is known only from a single locality in the Worcester District in the Southwestern Cape Province of South Africa.

The species disappeared around 1921 due to habitat loss caused by agriculture and urbanization.


syn. Mesembryanthemum vanzijliae L. Bolus


The photo below shows a congeneric taxon that occurs more or less in the same locality, the Runty Brightfig (Lampranthus debilis (Haw.) N. E. Br.).

Erepsia promontorii L. Bolus

Cape Erepsia (Erepsia promontorii)

The little Cape Erepsia was known to occur at three areas on the cape Peninsula, South Africa; one was Cape Point, a cliff at the southern end of the Cape Peninsula, the other two were at the town of Hermanus and at Sea Point, today a densely populated suburban of Cape Town.

The species was last seen in 1950 and is believed to be possibly extinct, howevere, it was found growing in the so-called Hangklip Sand Fynbos, a habitat that still exists at least at Cape Point, thus there is still some hope that this species might be rediscovered some day.
