J H. MAIDEN. 



Seed with a club-shaped aril and a funicle short or as 

 long as the seed, but not encircling it. 



Type from Leura, Blue Mountains, N.S.W. (A. A. Hamil- 

 ton) in National Herbarium of New South Wales. Identical 

 with Sieber's No. 464, which is figured at Plate 181, Part 

 xlviii of my "Forest Flora of New South Wales." 



The history of the species, and a description in English, 

 will be found at Part xlviii, p. 153 of my " Forest Flora 

 of New South Wales." 



Synonyms. — 1. A. crassiuscula Sieber. This name, how- 

 ever, is barred by reason of the earlier A. crassiuscula 

 Wendl. (See my Forest Flora, Part xlviii, p. 153). 



2. A. obtusata Sieb. var. Hamiltoni Maiden (loc. cit.) 



Range. 

 This species is at present only known from the higher 

 parts of the Blue Mountains. N.S.W., viz., from Leura to 

 Clarence Siding, and I invite the attention of observers to 

 extend records of its habitats. There seems no doubt that 

 this rare species is a disappearing one, and that it is dis- 

 playing a greater tendency to assume the vegetative method 

 of reproduction. It is becoming difficult to get ripe seeds, 

 and people who have it in their ground at Leura find that 

 it largely spreads by underground stems. 



Affinities. 



It is very closely allied to A. obtusata Sieb., figured in 

 my "Forest Flora of New South Wales," Part xlviii, Plate 

 177, in flowers. 



Mr. R. H. Oambage informs me that the seedlings of A. 

 Hamiltonlana have more bipinnate leaves than A. obtusata, 

 and that the internodes are shorter. Mr. Oambage has 

 described the seedlings of A. obtusata in this Journ., Vol. 

 Lit, p. 424 (1918), and will shortly furnish a description of 

 those of A, Hamiltoniana.
