NOTES ON ACMADENIA, B. AND W. 
This species is obviously allied to A. barosmoides , mihi, from which, 
however, it is at once distinguished by its smaller, broadly ovate or 
broadly elliptic glabrous leaves, not thickened at the margins, and 
with crenulate dentition, by the smaller flowers with dorsal glands on 
their petals, by the presence of staminodia, the pilosulate filaments 
of the fertile stamens, and the sparingly pilose style. The leaves recall 
those of Agathosma decora, mihi, also from the Matroosberg. 
Acmadenia macradenia, comb. nov. 
Sonder, in his original description of Adenandra macradenia fails 
to describe the petals and essential organs of this plant. In 1895 Bolus 
gathered a twig with two flowers at Piquetberg, which, though not 
wholly in agreement with the species, is sufficiently close, to regard as 
a variety of this long-lost plant, and which, on dissection of a flower, 
shows that they are devoid of staminodes, and have only five stamens, 
which therefore assigns it to Acmadenia. 
A. macradenia var. borealis, var. nov. 
Fruticulus pusillus?, ramulis brevissimis pubescentibus imbricato- 
foliosis. Folia late elliptica vel late obovata, apice rotundata, 5 — 8 mm. 
longa, 3-5 — 4-5 mm. lata, crasse coriacea, utrinque glabra, pallide 
viridia, complanata, baud convexa, dorso conspicue albido elevato- 
glandulosa, costata, margine incrassata, primo pilosula, apicem versus 
glanduloso-denticulata. Flores solitares, albidi (sicco), pedic.ellis 2 — 
3 mm. longis, albopilosis, ebracteolatis? Calyx 5 — 6 mm. longus, 
interne albo-pilosus, segmentislonge-triangularibus, obtusiusculis, dorso 
roseo-purpureis, nitidis, carinato-costatis, costis primo ciliatis, margini- 
bus creberrime pilosis, apicem versus glanduloso-denticulatis. Petala 
unguiculata, 1 cm. longa, limbo orbiculari, 7 — 8 mm. lato, dorso 
apice paullulo barbata, unguibus glabris. Stamina (5) 2-3 mm. longa, 
glabra. Pistillum ignotum.

Differs from the type ( Adenandra macradenia, Sond. of which 
Ecklon and Zeyher types, labelled A. coriacea, E. and Z. are in the S.A. 
Museum, Cape Town), by its dwarf er habit (if the specimen quoted (8420) 
is representative of a dwarf plant?), by its flat and not concave leaves, 
relatively broader and more coriaceous, and with a more prominent 
dorsal midrib. 
A. teretifolia, comb. nov. Diosma teretifolia, Link.; Sonder, in Flora tap. i, 
376, 1860. As Dr E. P. Phillips has pointed out (in MSS.), this plant 
is to be referred to Acmadenia, hence this new combination is pi oposed. 
Phillips states that the flowers are pink, though they dry a white. 
The following are more recent records not quoted in the Flora.
