12 Contributions to the Queensland Flora. 
mong previously described species 7’. compacta approaches most 
closely to 7’. oxycalyptra, from which it differs in its smaller flowers, 
fewer stamens, and smooth not papillate seeds. 
Through the kindness of Mr. J. H. Maiden I have been enabled to 
see a small piece collected between the Norman and Gilbert Rivers by 
Mr. T. Gulliver. This was referred by Mueller to 7’. cypseleoides from 
which, however, it differs in its flowers being pedicellate and solitary 
not in pedunculate cymes. In forwarding the specimens Mr. Maiden 
writes : “We have only a small specimen of Trianthema cypseleoides, 
one half of which is sent to you herewith, and is forwarded to yo 
without prejudice. It seems to be nearer T'rianthema oxycalyptra than 
the species named, but authentic nigliscaieal of the latter are required 
before a definite opinion can be given 
Until authentic specimens have been gathered 7’. cypseleoides must 
be omitted from the Queensland flora.

A medium-sized tree, branchlets lenticellate, glabrous except the 
young shoots which are fulvous pubescent. Leaves glabrous, lanceolate, 
shining above, apex tapering to a sharp point, margins undulate, 34-6 in. 
(9-15 em.) long, 1-1} in. (2°5-4-5 cm.) broad; the base tapering to a 
petiole of about 3 lines (7 mm.). Flowers on slender glabrescent pedicels 
of 6-8 lines (1-3-1-8 em.). Calyx-lobes 5, pubescent, oblong. Corolla 
not seen. Pistil 7 lines (1-5 cm.) long ; ovary pubescent with long hairs 
but soon glabrous ; style glabrous. Fruit about 2 in. or more in diameter, 
bluish black, exocarp succulent, exuding a milky sap when cut ; seeds 
1 or more, dark chestnut colour, not shining, ellipsoid, when more than 
one in a fruit somewhat 3-sided by compression, about 14 in. (3-7 em.) 
long and 1} in. (3 em.) broad ; hilum large, practically the whole length 
of the seed and nearly } in. (2 cm.) wide.
