thus indicate an approach to those of the Dzwzdrate, the calyces are nearly glabrous, 
the corollas are usually 5-cleft, necessitating a 5-denticulate calyx also, the fruits are 
still less broad, the seeds distinctly narrower but quite as long, the arillar appendage 
extends only to the basal part of the seed, and forms there a thick appendage from 
almost consolidated foldings of the funicle. 
A. Cunninghamz is evidently a more frequent species than 4. MWazdenzi ; thus it 
oceurs in the distributed collections of Madame Dietrich from Port Mackay, Lake 
Elphinstone and Rockhampton under the following numbers, so far as can be judged 
from flowering samples, all her specimens being devoid of fruit : 254, 381, 486, 539, 
553, 622, 851, 1651, 2502, 2539. The following localities are also additional to 
those recorded in 1864 in the second volume of the Flora Australiensis : Gwydir and 
Wide Bay (Leichhardt), Walloon (Bowman), Darling-Downs (Lau), Richmond 
River (Fawcett), Leichhardt-Downs (Wuth), Barcoo (Schneider). Confirmatory 
fruit-specimens are wanting also from all these localities, so that still some doubts 
may be entertained about the identifications, especially for the plants from the far 
inland-places. 
A. holcocarpa, which has the venulation of 4. glaucescens, is easily distinguished 
from A. Mazdenit in various respects, particularly in its rigid almost cylindric 
somewhat furrowed fruit, dark brown turgid seeds and long straight funicle, ending 
in a very small nearly cupular aril, as shown in the eleventh decade of the Icono- 
graphy of Australian Acacias. Mr. Dallachy noted this species as dwarf, the fresh 
flowers as fragrant and—strange to say—as white; so they must at all events be 
very pale ; but Solander likewise indicated the flowers of 4. calyculata as white, and 
thus the question arises whether perhaps the two species are identical. 
Specimens, but in flower only, from Fitzroy Island (Walter) seem referable to 
A. holcocarpa, but they accord so far also fully with the description of Cunningham’s 
plant from there ; the fruit, sent with his flowering specimens, may really belong to 
the rather widely distributed A. aulacocarpa. Visitors to Fitzroy Island could easily 
solve this enigma. A. holcocarfa has become further known from Cape Sidmouth 
(C. Moore), Trinity Bay (W. Hill), Rockingham Bay and Hinchinbrook Island, 
where it is common (J. Dallachy). It seems to be essentially a plant of coastal 
regions. A. leptocarfa is distinguished from A. MZazdenii in the phyllodes showing 
hardly any conspicuous anastomosing venulation, the interstices between the venules 
being also wider, in flowers less crowded along the rachis, in glabrous calyces, in 
generally 5-parted corollas, and in numerous almost consolidated folds of the funicle, 
these forming downward an appendicular mass of a length as great as the seed itself 
or even greater, though basal only; I find, however, the fruit-valves to a considerable 
extent flexuous. The phyllodes are without lustre. A. judzfera resembles in close
