R.O. Moffett. 1994.
Rhus longispina and Rhus pterota, two hitherto confused South African shrubs,
South African Journal of Botany 60: 4 3-49. ISSN 0254-6299,

Rhus longispina Eckl. & Zeyh. and R. pterota Presl are two woody shrubs which are common in the eastern and southern Cape Province. Because of shared habitats and a superficial morphological similarity, these species have been regarded as conspecific and known as R. longispina for over one hundred and fifty years. A table showing the diagnostic characters separating the two species and a detailed description of each is given, followed by a list of selected specimens indicating their distribution.

Rhus longispina vs Rhus pterota
.* Drupe: Oblate, ellipsoid 3.5 X 2.3 - 6.8 X 4.7 mm, chestnut brown, drying dark brown; resinous juice and dry drupes astringent but palatable VS elliptic, ellipsoid 5.6 X 4.3 - 6.4 X 4.9 mm, slightly asymmetric, dark reddish brown, drying black; resinous juice and dry drupes pungent, distinctly unpalatable leaving a burning sensation in the mouth
.* Foliage - new growth: glabrous, shiny VS russet, glandular
.* Leaves: Petioles semiterete, occasionally margined; leaflets olive-green above, slightly paler below, often laccate; apex often emarginate VS petiole flattened, distinctly winged; leaflets dull grey-green above, slightly paler below, never laccate; apex never emarginate
.* Secondary veins impressed, not prominent VS prominent above, dull yellow, divided towards margin, often somewhat reversed
.* Habit: When mature - large rounded shrubs up to 4 m high VS somewhat untidy squarrose shrubs up to 2 m high
.* Panicles: Axillary and terminal, latter prominently exposed VS fasciculate, not prominently exposed
.* Bark: Pale grey-brown to dull yellowish on younger branches, granular to slightly striate VS fasciculate, not prominently exposed
.* Distribution: on diverse substrates near the coast and widespread in the Little and Great Karoo VS on calcareous substrates along the coast and adjacent interior.

We definitely need the full copy of Moffett's FSA publication (which equates to an edited version of his doctoral thesis - is my understanding) to be available;- if not here then a link to enable interested parties to download it.

The stripped out version refenced above above is pretty meaningless.
Tony, please will you follow-up with Sanbi how to do this?

There are copyright issues. We can informally share, but cannot publically do so.

I take it that includes downloading a copy from a link. Sigh.

Yes, but not linking it ...
But it does not apply to personal copies. So unless you invisage thousands of requests, why not just send it to anyone who asks?

Happy to do that There are several who have it now and can do likewise.
Unlikely to be more than 10 who want it.
