NOTES ON ACACIA. 179 



globosis ca 15 floris. Bracteis longis, falcatis. Sepalis angusto- 

 spathulatis, apice ciliatis, petalis plus dimidio aequilongis. Petalis 

 laevibus. Ovario glabro. Legumen ac semina non vidimus. 



Doubtless a shrub, branchlets slightly angular, slightly 

 hoary pubescent like the phyllodia. 



Phyllodia linear-subulate, rather rigid, nearly terete, 

 flexuose, up to 7 cm. long, finely but clearly striate with 

 &bout six nerves, with a short, innocuous oblique point, the 

 base terminating in a short, rounded, scarcely decurrent 

 process. Stipules short, broad ish, scarious. 



Peduncles short (say 2 mm.), hirsute, bearing each a 

 globular head of about 15 flowers mostly 5-merous. Bracts 

 long, falcate. 



Sepals narrow-spathulate, divided to the base, fringed 

 with hair at the top, two-thirds as long as the petals. 

 Petals smooth, free. Ovary glabrous. 



Pods and seeds not seen. 



The type is Drummond's 5th Collection (1849), No. 5. A 

 co-type is Drummond's 4th Coll. (?) No. 132. 



Range. 

 This species occurs in Western Australia, and is only 

 known from Drummond's 5th and (? 4th) collections. His 

 5th Collection was probably made mainly in the southern 

 part of the State, but it is not possible to speak of a definite 

 locality and the attention of local botanists may be invited 

 to so well marked a species. 



Affinity. 

 With A. trlptycha F.v.M. It was included with this 

 species by Bentham (B. VI. ii, 337), as to specimens with 

 "flexuose" phyllodia. The two species can be sharply 

 separated by the absence of that character in A. triptycha, 

 and also by the base of the phyllodes, annular and non- 

 decurrent in A. triptycha. The flowers are also more 

 numerous in the latter species, being twenty and over.
