The flower buds are smaller and rounder, that is, less ribbed and pointed 

 than those of A. salicina, and also much more numerous in the head. 



SUB-SEBIES RaCEMOSAE. 



8. A. Jennerae,n. sp. — "295. At waterhole about 80 miles north-east 

 of C. (arrow), 2, 8th June, 1911." 



Frutex vel arbor parva, glaber, ramulis teretibus. Phyllodiis lanceolatis, reotis vel 

 pauUo ciirvatis, apice basique sensim attenuatis, 15 cm. longis et 1.5 cm. latissima parte, 

 l-nervosia, nervis secondariis angulum 30 nervum medium facientibus, nullis nervis, second- 

 ariis praecipue prominentibus. Racemis brevibus, capitulis globosis ca. 36-floris, pler- 

 umque 5-meris, calyce trimcato, brevissime lobato, parte superiore villoso, corolla calycem 

 oa. triente superante. Fetalis liberis, glabris. Pistillo laeve vel pruinoso. Leguminbus 

 vel seminibus non visis. Videtur A. difformi, R. T. Baker proxime affinis. 



A shrub or small tree, glabrous in all its parts, branchlets terete, or sUghtly 

 angular through the decurrence of thin ribs proceeding from the bases of the 

 phyllodia. 



Phyllodia lanceolate, straight or slightly curved, tapering gradually 

 to both ends, up to 15 cm. (6 in.) long, and about 1.5 cm. in the widest part. 

 With from 1-3 marginal glands. One-nerved, the secondary veins meeting the 

 midrib at an angle of about 30° and spreading. No secondary vein specially 

 prominent. 



Racemes rather short but loose, with several globular flower heads of 

 about 36 in the head, mostly 5-merous. 



Bract \\ ith circular dark-brown top, fringed ; on a slender pedicel. 



Calyx truncate, very shortly lobed, hairy at the top, extending two-thirds 

 or more up the corolla. 



Petals free, glabrous, except for a few scattered hairs. 



Pistil smooth or hoary. 



Pods or seeds not seen. 



The name is given in honour of Miss Ameha Maud Jermer, Librarian, 

 Botanic Gardens, Sydney, to whom I am indebted for useful assistance in the 

 preparation of this paper. 



This species belongs to the series Uninerves, Section Racemosae. 



In the absence of pods and seeds, it may be provisionally placed in the 

 penninervis-retinodes group, and its nearest afiinity appears to be A. difformis, 

 B. T. Baker, Proa. Linn. Soc, N.S.W., xxii., 154 (1897), a species which is, so 

 far as we know, confined to the drier parts of New South Wales. 



The differences appear to be absence of a second vein paraUel to the midrib, 

 which is often found in A. difformis ; the latter has also a more falcate phyUode 

 with a more rounded apex and a pecuhar thickening at the base. 



A. difformis has also longer racemes with more numerous heads of flowers. 



As regards the structure of the individual flowers I can detect no im- 

 portant difference between them and those of A. difformis. 



Considering all the points, I think there are sufficient differences between 

 the plant under consideration and A. difformis, to warrant a name being given 

 to it : its final position can only be assigned with certainty when fnuts are 

 available. 



9. A. salicina, Lindl., var. varian-s, Benih.
