N.S. Wales. — Acacia Plateau near the Queensland border, common 
in rain forest, C. T. White 12552 (type: fls. and fts.), March 1944 (tree 
up to 15 m. high, 0-33 m. diam., bark brown, rather flaky, leaves very 
glossy above, flowers white, fragrant). 
Queensland. — Moreton District: Mt. Glorious, Mrs. M. S. Clemens 
(fls.) Jan. 1945. 
I am indebted to Mr. R. H. Anderson for comparing this species 
with others from New South Wales. I thought it may be a form of 
M. fragrantissima F. Muell., a species very poorly represented in 
Australian herbaria. It differs in several characters, however, e.g., 
Leaves subacute, rounded or obcordate; veins discernible on 
lower surface, calyx 4-merous . . . . . . . . M. fragrantissima. 
Leaves long acuminate, veins not visible on the lower surface, 
calyx 5-merous . . . . . . . . . . . . M. sericocalyx. 
From the raceme-like inflorescence Mr. Anderson considers 
M. sericocalyx C. T. White to come closest to M. Bidwillii Benth. but 
this differs in the leaves being broader, the veins clearly discernible on 
both surfaces and the calyx being quite glabrous. I have never been 
able to distinguish satisfactorily M. Bidwillii Benth. from M. racemulosa 
Benth. and M. acmenioides F. Muell. 
Family Aizoaceae. 
Macarthuria ephedroides sp. nov. 
Caules numerosi, ramosi, 0-5-0-75 m. alti, suffrutices densos ca. 1 m. 
diam. formantes, ramulis glabris complanato-quadrangularibus. Folia 
sparsa squamiformia lineari-lanceolata, 3-7 mm. longa. Flores apetali, 
singuli vel pauci apicibus ramulorum dispositi, pedicellis 1 mm. longis. 
Sepala 5, libera, virescentia, ovata, acuta, 2-5 mm. longa, 1-5 mm. lata. 
Stamina 8, filamentis tenuibus in parte inferiore late expansis et in 
cupulam membranaceam connatis, antheris 2-locularibus. Ovarium 
triloculare, glabrum, ovulo in loculis 1. Capsula submembranacea, 
seminibus nigris vix 2 mm. longis dense et minute concentrice ruguloso- 
punctatis. 
Mitchell District: Enniskillen, in rocky sandstone hills, moderately 
common in small patches, C. T. White 12417 (fls. and capsules), Nov. 
1943 (subshrub, numerous stems — many of them dead — from a common 
stock, forming dense masses abt. 1 m. diam.).
