reinwardtii: after Reinwardt.

Rosette to 100mm φ, caulescent, proliferating.  Leaves many, to 70 X 20mm, ratio stem diameter to leaf width 1:1.2, erect spreading or incurved, scabrid, brownish-green, usually with flattened scale-liked tubercles.  Inflorescence simple or occasionally compound, to 300mm.  Flowers tepals fused, tube straight, inner lower tepals revolute.

1982 – H. reinwardtii is very closely associated with H. coarctata.  It occurs southeast of Grahamstown between the Kowie and Fish rivers and eastwards from the Fish River to near East London.  The differences between the two species are discussed under H. coarctata.  The forms of H. reinwardtii are often more striking than in H. coarctata because of the larger whiter tubercles.  The cytology of the species is very interesting (Brandham, 1974) and although fa chalumnensis is maintained here, there are in fact many other triploids and also tetraploids which could be equally recognised.  It is difficult to decide precisely what represents the species.  The forms olivacea, zebrina and kaffirdriftensis are all from the same very variable population.  The fa olivacea when grown in good light is fairly smooth with slender leaves and is a handsome olive‑green.  The fa zebrina has bands of confluent tubercles across the back of the leaf, whereas in fa kaffirdriftensis the tubercles are very large and white against a deep green background.  Brandham has shown that the genetic make‑up of H. reinwardtii is unusually unstable, and this may explain why this species on its own could be of interest to a collector.  It is interesting to consider that a young stemless rosette of H. reinwardtii could easily be confused with H. fasciata, particularly when the inner leaf surfaces are smooth.  The leaves in H. attenuata are a little too long and spreading for a similar resemblance to H. reinwardtii plants which have the leaf faces tubercled.  Similar associations can be made with H. coarctata.  The var. brevicula occurs west of the Fish River in the higher lying areas east of Grahamstown.  It is much smaller and more compact than the typical variety.

1999 – Some of the earlier varieties are here only upheld as forms as they were virtually based on single clones.  The list of specimens reflects the way in which G.G. Smith tried to observe species.  He appeared to be trying to find specimens which differed enough to attract attention.  It is not in the least clear where he may have placed the amorphous residue which would have remained after his classification was complete.

b. fa chalumnensis (Smith) Bayer :106(1976).  Bayer :72(1982).  H. reinwardtii var. chalumnensis Smith, JS.Afr. Bot. 9:99(1943).  Scott, Nat.Cact.Succ.J 36:38(1981).  Scott :45(1985).  Type: CAPE‑3327 (Peddie): Chalumna (‑BA), Smith 513 (NBG).

chalumnensis: from Chalumna.

The species occurs all around Chalumna and it is only the triploid vegetatively propagated clone which is this form.  It is much easier to grow in cultivation than many of the other clones which have been collected, but which seem never to have survived for long in cultivation.

c. fa kaffirdriftensis (Smith) Bayer :126(1976).  Bayer :72(1982).  H. reinwardtii var. kaffirdriftensis Smith, JS.Afr.Bot. 9:96(1943).  Scott, Nat.Cact.Succ.J 36:37(1981).  Scott :44(1985).  Type: CAPE‑3327 (Peddie): Kaffirdrift (‑AC), Smith 3364 (NBG).

kaffirdriftensis: from Kaffirdrift.

This variety is probably a single clone is from the east bank of the Fish River and Smith was also intending to name a very similar clone from west of Wesley.  The conspicuous tubercles are in longitudinal rows on the back of the leaves.

d. fa olivacea (Smith) Bayer :142(1976).  Bayer :72(1982).  H. reinwardtii var. olivacea Smith, JS.Afr.Bot. 10:142(1944).  Type: CAPE‑3327 (Peddie): Kaffirdrift (‑AC), Smith 5260 (NBG).

olivacea: olive green.

Unlike some of the other forms, this one has an unusual colour and its tubercles are a little rounder and sparser.  This character appears to a lesser degree in several clones collected on the west bank of the Fish River.  David Cumming also reports the form to be a more substantial element to the southwest.

e. fa zebrina (Smith) Bayer :169(1976).  Bayer :73(1982).  H. reinwardtii var. zebrina Smith, JS.Afr.Bot. 10:18(1944).  Scott, Nat.Cact.Succ.J 36:37(1981).  Scott :46(1985).  Type: CAPE‑3327 (Peddie): Kaffirdrift (‑AC), Smith 5258 (NBG).

zebrina: striped.

In this form the tubercles are very conspicuous and arranged in prominent white bands on the outer leaf surfaces.  The clone does not seem to have survived very well in cultivation and is thus not as vigourous as fa chalumnensis.

f. var. brevicula Smith, JS.Afr.Bot. 10:11(1944).  Bayer :104(1976).  Bayer :73(1982).  Scott, Nat.Cact.Succ.J 36:37(1981).  Scott :45(1985).  Type: CAPE‑3326 (Grahamstown): Frazers Camp (‑BD), Smith 3138 (NBG):  H. reinwardtii var. diminuta Smith, JS.Afr.Bot. 14:15(1948).  Type: Cape, Albany Div., Smith 5177 (NBG).

brevicula: very small.

This variety has some substance in terms of variability and distribution.  It does not seem to do well in cultivation and is consequently not often seen in collections.  Perhaps for the same reason it is not well-known and may transform to some degree in cultivation.  Scott does suggest that it occurs mostly as solitary individuals but this is not true as even his photograph shows.  The habitat is dominated by graasy fynbos to a lesser degree than in the case of H. coarctata var. adelaidensis.  H. coarctata var. huntsdriftensis was, according to Smith’s records, collected very close to the east of Frazer’s Camp where the vegetation also changes to Valley Bushveld.
