XCV. VERBENACE^E. 
[Xewcastlia. 
about as long as the tube, inserted above a woolly ring near the base. Ovary 
glabrous. Ovules attached near the top, but the seed enlarges upwards so as to 
be attached near the base. The fruit not seen however quite ripe. 
Hab.: St. George, J. IVedd. 
2. N, cephalantha (flowers in heads), F. v. M. Fragm. ix. 4. Leaves 
small, oblong-ovate with recurved margins, 1 to 1 in. long, somewhat thick, 
sessile. Flowers in sessile heads. Bracts small. Calyx tomentose-villous, teeth 
shorter than the tube. Corolla about 2 lines long. Style capillary, glabrous, 
scarcely 2 lines long. Stigma punctiform. Drupe globular, 14 line long, 
4-c-elled. 
Hab.: Lake Nash, Michael Costello. 
2. DICRASTYLES, Drumm. 
(Alluding to the 2-branches of style). 
Calyx more or less deeply divided into 5 lobes. Corolla-tube short, the limb 
of 5 nearly equal short lobes. Stamens 5, exserted ; anthers without appendages. 
Ovary 2-celled, with 2 ovules in each cell, laterally attached at or above the 
middle. Style deeply divided into 2 slender branches or lobes. Fruit small, dry, 
4-celled, with 1 seed in each cell. — Cottony or woolly undershrubs or small 
shrubs. Leaves opposite or scattered, undivided. Flowers small, in cymes 
collected into corymbose panicles, more rarely contracted into dense solitary or 
corymbose heads. Bracts and bracteoles very deciduous. 
The genus is limited to Australia. 
Leaves linear, 6 to 9 lines long. Flowers in elongated spike-like panicles 
3 to 4in. long 1. I). Costelloi. 
Leaves linear, about 6 lines long. Flowers in compact head-like cymes . . 2. B. Weddii. 
Leaves tin. or more long, 3 to 6 lines broad. Flowers few or many in each 
cluster 3. D. Doranii. 
Leaves 4 to 8 lines long, J to 1J line broad. Flowers few in each cluster . . 4. D. Lewellini. 
1. !D. Costelloi (after Michl. Costello), Bail. Bot. Bull. iv. An erect 
undershrub attaining about 18in. in height, slightly branched. Branches and 
stems terete, hoary-white with a close tomentum. Leaves scattered, often close, 
and appearing opposite or in whorls of 3, linear, obtuse, with revolute margins, 
from 4 to f in. long and 1 line broad, tomentose when young, the older ones 
rugose. Flowers in small clusters in an elougated terminal spike-like panicle 3 
or 4 in. long, only branched at the base ; each branch short, and bearing a sessile 
cluster or head of densely white tomentose flowers. Bracts and bracteoles 
lanceolate, minute, glabrous inside, the outside densely clothed with branched 
hairs like the rest of the plant. Flowers nearly globose, scarcely 2 lines in 
diameter, on very short pedicels. Calyx divided to near the base, densely covered 
with branched hairs outside, inside glabrous. Corolla-lobes twice as long as 
the calyx-lobes, the outside at the base tomentose, the tips glabrous and 
membranous, the inside glabrous except for a rather large patch of long simple 
hairs at the base of the lobes. Stamens opposite to and about half the length 
of the calyx-lobes ; filaments glabrous ; anthers glabrous, large and deeply lobed. 
Ovary and entire part of the style densely covered with white, flat, scale-like 
hairs like those on the other parts of the plant. Style-branches rather long and 
slender. 
Hab.: Near Lake Nash, on the boundary line between Queensland and the Northern 
Territory of South Australia, M. Costello. 
In many respects this new species approaches D. Beveridgei, F. v. M. Fragm. viii. 50 ; but no 
description is there given of the stamens, so one may suppose them to be exserted as in all 
previously described species. Thus I rely principally upon the difference in indumentum of 
llowers and length of stamens for distinguishing D. Costelloi from others of the genus.
