glabrous, petiolate, elliptic, slightly cordate at the base, 
apex apiculate, on the upper surface bearing 7-10 glands 
at the base; principal nerves about nine on either side of 
the midrib; petiole 2.5-4 cm. long, blade 10-12 cm. long, 
4.5-6 cm. broad. Flowers rather large for the genus, 
arranged in simple axillary umbels; peduncles 0.5 cm. 
long; pedicels stout, 2 mm. long; sepals glabrous, broadly 
ovate, 5 mm. long; corolla almost rotate, deeply cut into 
five lobes, lobes 1.2 cm. long, gradually narrowed towards 
the apex from a broad base; adnate part of the corona 
about as long as the segments; segments erect, more or less 
abruptly narrowed towards the top into a rather blunt 
point, longer than the anthers; stigma rostrate, much 
longer than the corona. 
Wide Bay District : Fraser Island, F. C. Epps (type : 
flowers), W. R . Petrie (leaves only). North Kennedy Dis- 
trict: Dunk Island, E . J. Banfield (fruits), Jan., 1906 (a 
comparatively slender vine, not more than i inch diam. 
at the thickest point, yet climbing up fairly tall trees), 
The present plant in general appearance is very 
similar to M. araujacea F. Muell. but the two species can 
be distinguished as follows: — 
Branches and foliage sprinkled with hairs, 
leaves cordate at the base, in the dried 
state the basal lobes overlapping and con- 
cealing the glands ; sepals pubescent .... M. araujacea 
Branches and foliage glabrous, leaves 
slightly cordate at the base, in the dried 
state basal lobes not overlapping, basal 
glands prominent; sepals glabrous .... M. glandulifera 
Mr. S. T. Blake, who is making a special study of the 
Australian and Papuan Asclepiadaceae, has pointed out 
that the new species here proposed approaches in some 
respects the genus Thozetia, especially in the tendency of 
the rachis of the umbels to become elongated as the flowers 
develop. It is also marked as in Thozetia by prominent 
disk-like scars from where the flowers have fallen. This 
elongation of the rachis is scarcely perceptible in M. arau- 
jacea F. Muell.
