Only another species has been described, viz., A. rosafolius A. Cunn., the 
New Zealand tree on which the genus was founded. 
Yar. hirsuta. Maiden and Betche. 
Proc. Linn. Soc. N.S.W., xxxvii, 240 (1912). 
Branchlets, rhachis of the pinnate leaves and principal veins on the underside of the leaves densely 
covered with short, spreading, pale-brown hairs, more sparingly hairy on the smaller reticulate veinlets. 
Upper side of the leaves quite glabrous, or with hairs on the midvein only or sparingly sprinkled with 
hairs even on the reticulate veinlets. 
This is apparently the form mentioned by Mueller in Fragm. vi, p. 188, from Camden Haven, 
Macleay River and Bellinger River, but it is such a very distinct form that it should be constituted a named 
variety, in our opinion. It seems to be confined to the coast district and mountain ranges from Camden 
Haven to the Bellinger River, or from about 30 to 32 S. lat. It does not seem to extend into 
Queensland, so far as we know. 
Speaking of this species in the Agric. Gaz. N.S.W., v, 609 (1894), I used 
these words : 
My specimens have leaves all either perfectly entire, or with serrations so small as to be detected 
with difficulty. In the Dorrigo Forest Raserve (and, perhaps, also in Glenfernie) there is a form of this 
species with softly tomentose leaves and young shoots, and with the leaves morn digitate than in the type 
form. This is evidently the plant referred to by Baron von Mueller (Fragm. vi, 188) from Camden 
Haven, the Macleay and the Bellinger. The Dorrigo is, therefore, an important additional locality. The 
variety is so marked that I would suggest to the Baron the propriety of designating it tomentosa. 
I wrote to Baron von Mueller, but he did not adopt the suggestion, 
apparently thinking that he had referred to it sufficiently. 
Botanical Name. Ackama. Allan Cunningham, in his definition of the 
genus (op. cit.), says, " The name of this distinct genus has been invented by 
anagrammizing that given to the tree by the natives." His brother, Richard 
Cunningham, had given the Maori name as " Maka-maka." 
Muelleri, in honour of the late Baron von Mueller, Government Botanist of 
Victoria. 
Vernacular Name. Because of its corky bark, it invariably goes under the 
of " Corkwood " i 
a number of other trees. 
name of " Corkwood " in the districts in Avhich it grows. It shares this name with 
Synonym. Weinmannia paniculate F. Muell., Fragm. ii, 83, afterwards 
altered to W. paniculosa, and maintained by Mueller in his " Census of Australian 
Plants." 
Mueller follows Asa Gray in combining Ackama and Weinmannia. Ackama 
differs from Weinmannia in the paniculate inflorescence and valvate calyx, which 
is uniformly racemose in Weinmannia, which gives the two genera a different habit. 
The fruit also is different. 
Leaves. Mueller describes the leaves as " foliis trifoliolatis v. pinnatim 
quinquefoliatis." Trifoliolate specimens seem to be rare (e.g., Glenfernie Forest 
Reserve, Graf ton- Armid ale Road), all our other specimens have at least 5 leaflets.
