specimens had been labelled in the Queensland Herbarium as H. austral- 
asica F. Muell., a native of the Northern Territory. This species is 
known to me only from the description in the “Flora Australiensis” 
(Yol. 5, p. 405), which might however fit several species of the genus. 
From the locality records given it is very unlikely it is identical with 
H. glabrescens. 
The differences between H. ferruginea F. Muell. and H. glabrescens 
C. T. White can be set out as follows : — 
Leaves always prominently toothed, ferrugineous-pubescent under- 
neath on the midrib, secondary and tertiary veins, the hairs 
sometimes almost disappearing from the two latter but never 
totally absent from the midrib, base commonly subobtuse, 
petiole without any prominent pulvinus. Perianth not exceeding 
5-6 mm., densely ferrugineous-pubescent . . . . H. ferruginea. 
Leaves toothed or almost entire, quite glabrous on both sides in the 
adult stage, base cuneate, tapering into a short petiole with a 
rather prominent pulvinus. Perianth 1-1.2 cm. glabrous . . H. glabrescens. 
Family Thymelaeaceae.

I am indebted to Mr. A. W. Jessep, Director and Government 
Botanist, Melbourne Botanic Gardens and National Herbarium, for part 
of the type and fragment from another collection of P. penicillaris F. 
Muell. Mueller’s plant was described from female, mine from male 
specimens and I should say represent the one species. 
Family Eupiiorbiaceae. 
Cleistanthus densiflorus sp. nov. (Sect. Australes). 
Arbor, ramulis robustis junioribus ferrugineo-pubescentibus adultis 
glabris cortice griseo, crasso obtectis. Folia lanceolata. utrinque viridia 
sed subtus pallidiora, glabra, reticulata, apicein versus angustata sed 
apice ipso subobtusa, basin versus in petiolum crassum brevem angustata ;

fasciculos densifioros sessiles axillares dispositi; bracteae dense hirsutae. 
Flos masc. : — Calyx glaber, 3 mm. longus, profunde 5-lobatus. Petala 5, 
squamiformia spathulata. Stamina 5, columna filamentis longiora. Flos

In the absence of seeds for examination it is not quite certain 
whether the present species belongs to the section Australes Jabl. or 
section XanopetaJum (Ilussk). Pax. The latter contains no Australian
