NOTES ON ACACIA. 469 



Within certain limits I have observed a good deal of 

 variation in the length and folds of the f unicle in the same 

 species, but many more observations require to be made in 

 this direction. 



It is stated that the long funicle, i.e., where it encircles 

 the seed twice or thrice, is peculiar to Australian Acacias, 

 but the precise number of species with long funicles has 

 not been ascertained. 



The following list includes most of the species with 

 encircling or nearly encircling funicles. It will be observed 

 that they mainly belong to the series Uninerves and PlurL 

 nerves, and mostly, though by no means inclusively, belong 

 to regions of comparatively high rainfall : — 



Pungentes (Uninerves) — A. genistoides A. Cunn. and A. tetra- 

 gonophylla F.v.M. 



Uninerves (Brevifolise) — A. Meissneri Lehm. 



Uninerves (Racemosse) — A. penninervis Sieb., A. falcata Willd., 

 A. gladiiformis A. Cunn., A. Wattsiana F.v.M., A. 7iotabilis 

 F.v.M., A. retinoides Schlecht., A. Mabellce, n. sp., A. rubida 

 A. Cunn., A. Flqcktonice, n. sp., A. amoena Wendl., A. 

 Chalkeri, n. sp., A. Harveyi Benth. 



Plurinerves (Nervosse) — A. cyclopis A. Cunn., A.homoclada F.v.M., 

 A. melanoxylon R. Br. 



Plurinerves (between Dinridiatse and Nervosa) — A. or aria F.v.M. 



Plurinerves (Dimidiatse) — A. binervata DC. 



Juliflorse (Falcatse) — A. auriculiformis A. Cunn. 



Juliflorse ( Dimidiatse) — A. cincinnata F.v.M. 



I am much indebted to Miss Margaret Flockton, Artist, 

 Botanic Gardens, for the valuable assistance she has 

 rendered with her drawings (not reproduced) of all the 

 species referred to.
