You could try G. Williamson at department of botany in the University of
Cape Town. He have described a new species in the genus in 1998.

Williamson, G. 1998. A new Tylecodon Species (Crassulaceae). Cactus and
Succculent Journal 70:127-128.

In future you can use the excellent database of tropical flora at mobot to
find the authors of genuses and species.

For those of you who are not professional botanists, you may be interested to
know that Tylecodon is an anagram of Cotyledon, which is the genus it was split
off from. Botanists somtimes use this little trick when describing a new genus.

Happens often (Tecoma and Cotema, Albizia and Balizia, etc).
It is a device to help remember and place a new genus.
Another form is to add a prefix (Neo-, Para-, Pseudo-, Notho- etc, etc) or a
ending (like -opsis). The fun starts when such genera prove to be not
closely related (Tsuga and Pseudotsuga) or even belong to different
families (Cedrela and Cedrelopsis)!

By the way what may be even less obvious to "not professional botanists" is
that Cotyledon is a technical plant term used in morphology and thus is
potentially confusing. Using such a technical plant term as the name of a
genus is therefore not allowed for new names (after 31 December 1911. Art
20.2). Encountering such a name means that it is a fairly old name, in this
case by Linnaeus (actually Tournefort, but he does not count).

In a sense it is comparable to Latin cultivar epithets. New cultivar
epithets in Latin can not be published since 1 January 1959 (17.9).
Encountering a Latin cultivar epithet means encountering a cultivar of
decades old (unless it is an existing personal or geographic name, or if it
used to be a species or infraspecific taxon sensu ICBN).

Graham Williamson described a few new species but it is Ernst Van Jaarsveld
at Kirstenbosch who is writting a book on Tylecodon and Cotyledon due out
sometime in 2003.

Do a Google search and you will be surprised who did a review of the genus.

The review is overdue for an update because new species are continually
being described for the genus.

There's certainly nothing on the web more useful than the piece done by Stephen
Jankalski. Here's the URL:
http://groups.yahoo.com/group/Fatpla...20REVISED.html

While we're talking, was Tylecodon hallii named after this man? (seems
unlikely...)
"hallii: after Harvey Monroe Hall (1874-1932), who was born in Illinois, and
was an authority on
the Asteraceae of Southern California, a graduate of
and professor of botany at the University
of California, and a pioneer in experimental
taxonomy. He was the author in 1902 of A Botanical
Survey of San Jacinto Mountain, and was a collector
of plants in the Mt. Pinos region in 1905
and on Santa Cruz Island in 1908. He was placed in
charge of the University of California
Herbarium at Berkeley in 1902, became an instructor
in botany in 1903, and subsequently
became an assistant professor and then an associate
professor in 1916. In 1919 he joined the
Carnegie Institution in Washington, which established
its Division of Plant Biology on the
Stanford Campus, where he also became a professor of
botany. At the same time he became
Honorary Curator of the University of California
Herbarium, a position which lasted until 1932.
After a trip to Europe in 1929 to study natural
reserves, he proposed the creation of "Natural
Areas," and specifically the White Mountains and
Harvey Monroe Hall research areas near
Yosemite National Park (ref. Caulanthus hallii,
Galium hallii, Grindelia hallii, Tetracoccus
hallii)"

No, it was named after the famous South African plantsman and plant
collector Harry Hall (1906-1986), as were a number of southern African
succulents and bulbs.

He was born in Liverpool, England, emigrated to South Africa in 1947 and
became a botanist at National Botanic Garden in Kirstenbosch, S Africa. He
was awarded a FELLOW of USA CSSA in 1981.

Adromischus are not Tylecodon.

I think it's a phishing troll. He posted a different question in another
