196 _ A. J. EWART, JEAN WHITE AND J. R. TOVEY. 
Senecio Gilberti, Turcz. (Composite). Darling Ranges, 
W.A. M. Koch, 1907, No. 1692. 
Very rare; the herbarium contained only one imperfect 
specimen (Drummond, 325, Swan River). The heads, as 
pointed out by Bentham, resemble those of Hrechtites 
arguta, DC., but have no ligulate female ray florets, all 
being tubular. 
Tetratheca hirsuta, Lindl., (Tremandres). Darling Range, 
W.A. M. Koch, 1906, Nos. 1410, 1410a. 
The specimens shew all degrees of transition from alter- 
nate to verticillate leaves, and in other respects also bear 
out Mueller’s reduction of T. viminea, Lindl. (and also of 
T. pubescens, Turez.) to varieties of T. hirsuta. A white 
flowered form (Woorooloo, W.A., M. Koch, 1907, No. 1711) 
belongs to the same species, although it differs from Old- 
field’s white flowered variety in the leaves and in being 
less hairy (variety alba). 
Tillaea exserta, F. M. Reader, (Crassulaceze). 
This species though close to T. Sieberiana, Schultz, can 
be distinguished by the larger carpels when in fruit. The 
accompanying figure was prepared by Eckert under Mr. 
Reader’s direction at Baron von Mueller’s request, in order 
that he (Mueller) could describe the plant, which Mr. 
Reader did after the Baron’s death, but the figure not being 
available was unpublished. Additional localieties are, 
Near waterholes, Polkemmet, Victoria, 1898, F. Reader ; 
Oakgrove, Little Desert, 1897. 
Tillaea acuminata, F. M. Reader, Vict. Nat., 1878, Vol. xv, 
p. 96 = T. Sieberiana, Schultz, (T. verticillaris, DC.) 
var. acuminata. 
On Mr. Reader’s original specimen the label is also 
changed so as to reduce the species to a variety of T.
