In the Census of New South Wales Plants, now in the press, it will appear 
under a new under-section ( Uninerves) of Jtiliflorce. 
Affinities. In the original description we made the following statement : 
The affinity, of this species lies with A. rubida A. Cunn, A. obtusata Sieb., and A. amcena Wendl. ; 
but it is distinguished from them all by the oblong flower-head attaining fully | inch in length, and almost 
connecting it with the section Juliflorce. Its hairy pods distinguish it also from the allied species. 
As regards A. rubida and A. amcena, these two species have long glabrous 
pods, with funicles which twice encircle the seed, nor does A. Dorothea flower while 
hipinnate leaves are present. There are other differences, as may he seen from the 
plates. 
Perhaps, on the whole, the closest affinity of A. Dorothea is with A. obtasala, 
and therefore it may be convenient to set out the differences as follows : 
obtusata. 
Branchlets ... Glabrous, speckled, angular. 
Phyllodes ... Inclining to spathulate, slightly 
mucronate ; glabrous, one gland. 
Inflorescence ...' Flowers in round heads of about 
16-18; calyx tufted with hairs 
at the top ; corolla glabrous, 
except a few scattered hairs. 
Ovary glabrous. 
Pods ... ... Broad, long, containing 7 or 8 seeds. 
Smooth. 
Dorothea. 
Silky tomentose ; angular. 
Narrowing at the tip, mucronate, 
usually recurved tomentose (sil- 
very, often golden at the tips), 
one gland. 
Flowers in short spikelets, 
about 20-24 ; calyx tomen- 
tose; corolla glabrous, except 
a few scattered hairs. Ovary 
densely tomentose. 
Small, containing 2 or 3 seeds. 
Tomentose. 
Botanical Name. Acacia, already explained (see Part XV, p. 104); Dorothea ; 
loc. cit. occur these words, " The species is named in honour of my daughter, 
Acacia Dorothy Maiden (in fulfilment of a long-standing promise)." 
Foliage. This is silvery leaved, with the young leaves (phyllodes) some- 
times golden. 
Flowers. They are sweet scented and of a bright yellow colour. 
Fruits. This appears to he a shy fruiter, and seeds seem to be excessively 
rare. It seems to rely upon vegetative reproduction more than on seeds. 
Habitat. It is confined to the Blue Mountains and spurs, so far as is known 
at present, being very abundant at Lcura, and extending to Clarence Siding, Mount 
Wilson, and the Jenolan Caves. It occui-s at Ncwnes Junction (A. A. Hamilton), 
and also about 15 miles north of Clarence, towards Wolgan. 
In "Observations on the occurrence of two rare Acacias at Lcura, Blue 
Mountains," " Australian Naturalist," ii, ISO, Mr. A. A. Hamilton gives some 
detailed notes as to habitats for this species.
