in N.W. Australia, and doubtless there- 
fore tbrough the whole of Central 
Australia. 
8c<BVola microcarpa^ Cavan. Icon. VI, 509. 
Wonnomulla, 
Singularly enough, the plant, at least in its 
normal form, has not yet been noticed in 
Australia Felix, although it grows in 
East Australia, and even abounds in 
many parts of the South Australian 
Colony. 
The drupe is either onc-celled, -with one 
biconvex seed, or two-celled, with two 
plane-convex seeds. 
Se(Bvola collai*is. (Sect. Grymnostegia.) 
Glabrous ; upper part of the branches 
angular; leaves thick, elongate, broad- 
linear, acute, quite entire, sessile, nerve- 
less, narrowed towards the base, and 
there somewhat channelled ; pedicels 
axillary, solitary, twin or ternate, with 
minute semi-lanceolate-cymbiform brac- 
teoles at their base, a little shorter than 
the calyx; tube of the calyx gradually 
tapering into the pedicel and into a long 
narrow neck ; teeth of the calyx ovate- 
lanccolate. short, acute ; corolla yellowisli, 
one-lipped, glabrous, inward with very 
mimite papils ; its lobes lanceolate-linear, 
acute, winged; style pubescent; indu- 
sium pale, glabrous, without cilia; ; 
anthers linear-oblong, blunt ; d'inipe dry, 
woody, ovate, fm*rowed, 8-rihbed, two- 
celled, terminaied hy a long nt 'h. 
On sand ridges near Wonnomulla. 
Of this highly interesting plant occurs only 
a fragment in the collection. It seems 
shrubby or at least suffruticose. Branches 
below terete, with slightly bearded axils. 
Leaves alternate or fasciculate, generaUv 
2- 3 inches long, 1^25" broad. Pedicels 
flower-bearing long, fruit-bearing 
3- 4*" long, angular, at last upwards 
thickened. Bracteoles and teeth of the 
calyx about long. Corolla about 5" in 
length, scarcely to the middle 5-lobed,with 
entii'e wings. Filaments glabrous, linear, 
as wen as the style scarcely V/' long. 
Pollen-grains yellow, spherical, S-porose. 
Stylewithshortwhitedowns. Fruit almost 
spmdle-shaped, its turgid portion about 
Y long, its neck measuring fully 2"'. 
Pericarp dry, only laxly covering the 
furrows between the ribs of the thick 
mesocarp, leaving therefore longitudinal 
cavities beneath. Seeds solitary in each 
cell, albuminous, oblong-semi-cylindrical, 
about 2'" long. 
The curious form of the fruit offers a striking 
mark of distinction in this species, and an 
unexpected approach to the genus Lech- 
enaultia.
