CONTRIBUTIONS TO THE QUEENSLAND FLORA, NO. 9.

Calotis scapigera Hook, in Mitchell’s Tropical Australia 75 (1852). 
I have attempted to separate these two species in section 10 of the 
dichotomous key but failed to make the distinctions at all satisfactory. 
Several specimens collected by C. E. Hubbard in Queensland have all 
been distributed from the Royal Botanic Gardens, Kew (Eng.) as 
C. scapigera Hook., though following the key by Bentham in the “Flora 
Australiensis ’ ’ and that of J. M. Black in 4 * Flora of South Australia, ’ ’ 
1 would have identified them as C. scabiosifolia Sond. & F. Muell. 
An examination of the types of the two species is highly desirable. It is 
extremely likely that we are dealing here with one polymorphic species. 
Bentham in the “Flora Australiensis” noted no less than five named 
varieties of C. scabiosifolia Sond. & F. Muell., an indication of great 
variability. 
Calotis scabriuscula sp. nov. 
Herba perennis erecta, scabriuscula, pilis plus vel minus erispis 
plerumque glandula minuta terminatis dense vestita ; eaules foliosi. 
Folia spathulata vel elliptica apice acuta vel subacuta basi sessilia vel in 
petiolum semiamplexicaulem gradatim angustata, margine in parte 
superiore dentata vel raro integra, 3-4 cm. longa, 0*7-1 cm. lata. Capitula 
pedunculata ; involucri phylla lanceolata vel anguste ovata, acuta, 7 mm. 
longa ; ligulae numerosae, albae, elongatae ; capitula fructifera 1*7 cm. 
diam. Achaenia plana obovata hispido-muricata, 2*5 mm. longa, aristis 
2 fere aequalibus quam achaeniis fere triplo longioribus basin versus 
leviter dilatis, apicem versus retrorsum barbatis et squamis 2 oblatis 
terminata. 
Warrego District: Chesterton, approx. 25° 20' S., 147° 20' E., in 
Callitris-Eucalyptus forest on very sandy soil ca. 1,900 ft., S. T. Blake 
11140 (fig. and ftg. heads), 8-4-1936 (erect more or less spreading 
branched annual up to 6 in., leaves subglaucous above, glaucous beneath, 
ray white, disc yellow). 
The present species comes closest to C. dentex R. Br. but the two 
can be distinguished as follows : — 
Pubescent or nearly glabrous ; leaves linear or linear-lanceolate, very 
deeply toothed or almost pinnatifid in the whole length, sessile, 
base semi-amplexieaul, achene with 1 or 2 awns, in the latter 
case one markedly smaller than the other; a coastal or near 
coastal plant . . . . . . . . . . . . . . C. dentex. 
Densely pubescent; leaves spathulate or elliptic, mostly narrowed at 
the base into a semi-amplexieaul petiole, toothed in the upper 
part or sometimes entire or nearly so, achene with 2 nearly equal 
awns ; an inland plant . . . . . . . . . . . . C. scabriuscula 
Calotis scabriuscula C. T. White var. lobata C. T. White var. nov. 
Folia cuneata vel cuneato-spathulata, apice profunde lobata. 
Darling Downs District : Eukey via Stanthorpe, Mrs. E. Goebels 
(ftg. heads), Nov. 1944. 
This variety has the appearance of a large form of C. cunei folia 
R. Br. but the fruiting heads are twice as large, as in C. dentex R. Br. 
and C. scabriuscula C. T. White, and the awns are only barbed at the 
ends, as in those two species.
