Acacia prolifera, nov. sp. (Tab. xxii.). Frutex ramosus 

 viscidus glaberrimus sesquimetralis usque bimetralis, ramis 

 ramulisque valde costato-angulatis, phyllodiis rigidis linearibus 

 quadricostatis quadrisulcatis resinoso-marginatis rectis vel 

 falcatis 3-9 cm. longis lJ-2 mm. latis 1 mm. crassis apice 

 pungentibus basin versus paulo angustatis, glandula marginali 

 5-10 mm. supra basin sita saepe nulla, racemis 3-5-oeplialis 

 quasi proliferis partem inferiorem apliyllam rhacheos superne 

 foliosae occupantibus, pedunculis 10-12 mm. longis, capitulis 

 globosis 15-20-floris, floribus pentameris glabris, sepalis 

 lineari-spatliulatis, petalis leviter conjunctis sed mox liberis 

 uninerviis calyce semel'longioribus, bracteola superne cucul- 

 lata, ovario glabro, legumine uon viso. 



Wynbring or Barton, East-West railway (J. M. B.) ; 

 flowering September 22, 1920. This species seems to be 

 nearest to A. guadrisulcata, F. v. M., from whicb it differs 

 in the much longer phyllodes, the sepals glabrous and half 

 as long as the petals, the ovary glabrous, and in the 

 inflorescence. To understand the inflorescence fully would 

 require further observation of the shrub during the flowering 

 and fruiting period. As seen at the time of gathering, the 

 3-5-headed racemes formed the lower part of axillary shoots 

 bearing flower-heads towards the base, and in the upper part 

 bearing young phyllodes which were soft and flexible, but 

 otherwise similar to the mature, rigid, pungent-pointed ones. 

 In a few instances the upper part of this* growth, which should 

 probably be considered the leafy rhachis of the inflorescence, 

 had fallen or been broken off, and the question remains as to 

 what becomes of the leaf-bearing portion in other cases during 

 the fruiting season. All the shrubs seen were healthy and 

 apparently normal, two or three enlarged ovaries crowning 

 those heads from which the flowers had fallen, and giving 

 promise of curved pods. 



Acacia salicina, Lindl. ''Native Willow" (S. Austr.) ; 

 ''Cooba" (N.S. Wales). (PI. xxiii.) 



Acacia lig-ulata, A. Cunn. '• Umbrella Bush." ( 1 ]. xxiii.) 

 The vexed question as to the correct scientiflc names 

 of the "Native Willow" and the "Umbrella Bush" is in a 

 fair way to be settled by a note received from Lieut. -Col. Sir 

 D. Prain, Director of the Royal Botanic Gardens, Kew, to 

 whom I forwarded specimens of each, with a request that they 

 should be compared with the types. The note, which bears 

 date June 22, 1920, is as follows: — 



"In 1909 we looked into the question of the identity 

 of Lindley's type specimen of Acacia salicina, which is at
