the younger Forster gave a fuller description but renamed it Dorstenia pubescens. 
Persoon,” while citing H. sessile as a synonym, and only by implication referring 
to its later designation, named it Elatostema pubescens. A strict construction of 
the rules, would reject H. sessile in favor of H. pubescens (Forst. f.) Pers. The 
quotation might seem to imply that E. tetrandum was the specific name intended 
by the Forsters, but this is certainly not the case. 
It is possible that the wider-leaved plants referred to above may represent 
the missing EH. tomentosum Wedd., which would very satisfactorily explain its 
later reduction by its author to EZ. sessile. The narrower-leaved plant, at least in 
this herbarium, seems quite immature, it is possible that it may be a young plant 
of what is here named E. angustatum, but so far as present collections can decide 
the matter, the stipules seem to prohibit such a conclusion. However, these are 
also absent from the broader-leaved plants of Cuming’s collection.

Receptaculis staminiferis sessilibus, bracteis exterioribus orbiculari- 
ovatis, subcorniculatis; floribus tetrameris : receptaculis pistilliferis ses- 
silibus; bracteis exterioribus late orbiculari-ovatis, breviter corniculatis, 
ceteris lanceolatis vel oblongo-lanceolatis: erectum, simplex, caulibus 
dense retrorse subappresse strigosis; foliis oblique et anguste ellipticis 
vel oblanceolatis, basis uno latere acutis, altero subariculatis, margine 
crebre dentatis, apice acuminatis; stipulis lanceolatis, acutis, circiter 3 
mm. longis. 
Monoecious or dioecious: staminate receptacles sessile, outer bracts 
orbicular-ovate, free from one another except ‘at the base, 3.5 mm long, 
pilose, ciliate, thickened except at the apex and margins, barely corn- 
iculate; next pairs nearly as long, much thinner in texture, obovate, 
ciliate, barely corniculate ; bracteoles narrowly oblong-oblanceolate, cornic- 
ulate; perianth-segments 4, excluding the apical hairs about 1 mm long, 
oblanceolate; anthers 0.6 mm long: pistillate receptacles sessile; outer 
bracts free nearly to base, about 2 mm long, 3 mm wide, broadly 
rounded, somewhat corniculate; other bracts numerous, lanceolate or 
oblong-lanceolate; all pilose and ciliate; bracteoles oblanceolate, exclud- 
ing the dense apical tuft of hairs 1.5mm long; perianth-lobes 3, often 
long for the genus, up to 0.2 mm; achenes brown, ellipsoid, 0.6 mm 
long, coarsely longitudinally striate. 
Erect except at base, succulent, unbranched, about 20 to 30 em high, 
the stems densely retrorzely short-strigose: leaves subsessile, the lamina 
membranaceous, obliquely and narrowly elliptic or oblanceolate, 5 to 8 
em long, 12 to 20 mm wide, one side of the base acute or subobtuse, the 
other shortly auriculate, the margins except at the base with crowded, 
curved, often apiculate teeth, about 30 on the wider side, somewhat fewer 
on the narrower, the lowest minute, the apex gradually contracted into 
an acumen 1 to 1.5 em long, definitely triplinerved, the nerve of the 
narrower side more often arising over 8 mm from the base, additional
