Discussion
The name A. subporosa appears in no horticultural listing except that of Riedel (1957). However, LASCA (1970) tabulates it from two current trade catalogues which availability may render it more frequent. Austin Griffiths says (in litt.), “They are finding Acacia subporosa very satisfactory under cultivation in that region [Montecito area], mainly citing its adaptability to relatively impervious soils and tolerance to normal gardening moisture levels.” The above paragraph relates to A. subporosa Hort. which includes two species as understood in Australia: A. subporosa and A. cognata Domin, first described as A. subporosa var. linearis Benth. I initially recognized only A. subporosa; my acceptance of A. cognata in deference to Australian viewpoint as expressed by Tindale (in litt. and annotations) comes a couple of years subsequent to study of U.S. material. My notes indicate that most U.S. material is of the narrow-leaved form, A. cognata.
