Warrego District : Dynevor Downs, common on dry stony hillsides 
and ridges, C. T. White 11871 (type: flowers), 2-4-1941 (shrub 1 m., 
spreading habit, flowers white) ; near Adavale, on a range, Dr. W. 
MacGillivray 955 (flowers), 29-8-1923 (beautiful white-flowered shrub). 
(These last specimens were distributed from Herb. A. Morris as T. 
oligandra F. Muell. var. parviflora F. MuelL) 
In its irregular number of stamens the present plant agrees with 
some species of Baeckea but has the persistent petaloid sepals and 1-celled 
ovary of Thryptomene. The stamens are mostly 6 in number but vary 
from 6-8, in the latter case 1 or 2 being opposite a petal. In botanical 
sequence the species comes between T . Mitchellia%a F. Muell. and T. 
Miqueliana F. Muell. but in addition to floral characters differs from both 
in the narrow, linear not oblong or obovate leaves.

Family Compositae. 
Calotis inermis Maid & Betche Proc. Linn. Soc. N.S. Wales xxvi.,

Warrego District : Goonamurra near Eulo, on hard red soil flats, 
S. L. Everist 1656 (flowers), 20-9-1938 (small erect herb, ray florets 
purple) ; Dynevor Downs, on hard dry stony ridges, C. T. White 11827 
(flowers), 2-4-1941 (herb, flowers mauve). 
The above specimens seem to agree well with the description 
published by Maiden and Betche except that I would hardly call the 
hairs scale-like, nor would I say the achenes are striate. On this account 
specimens were forwarded to the National Herbarium, Botanic Gardens, 
Sydney, where they were examined by Miss Melvaine, who reported that 
the Queensland plants were entirely conspecifie with the only remaining 
specimen, from close to the type locality, of Calotis ineirmis in their 
Herbarium, the type having been evacuated. Miss Melvaine states that 
the achenes certainly do not appear striate, though it is possible that 
the mature fruits have that appearance. The description of the hairs, 
she says, presumably refers to their flattened character in the collapsed 
dried state when they do resemble narrow scales, though they are 
apparently narrowly conical when fresh.
