4. T. pilosa (hairy), F. r. M. Fraym. i. 174; Benth. FI. Austr. iii. 330. 
Procumbent, from a few inches to above 2ft. in length, hirsute, with spreading 
hairs, particularly long and dense about the inflorescence. Leaves obovate, 
narrowed into a rather long petiole, the largest attaining about lin. Flowers in 
axillary sessile clusters. Calyx when full grown about 3 lines long ; lobes ovate- 
lanceolate, very open, as long as the tube. Stamens about 20. Ovary of 1 
carpel, the style lateral, below the end, which soon closes round it; ovules 2. 
Capsule included in the calyx, produced into a cylinder concave or cup-shaped 
at the top round the style, circumsciss about the middle of the basal seed-bearing 
portion.

5. T. rhynchocalyptra (beaked capsule), /-'. r. M. Fraym. i. 174 ; Benth. 
FI. Austr. iii. 330. Perennial, forming dense prostrate tufts, sometimes only 2 
or 3in. diameter, sometimes woody at the base, the branches extending to Gin., 
more or less hirsute, with rigid bristly or soft spreading hairs. Leaves oval or 
oblong, obtuse, rarely above Ln. long, narrowed into a short petiole. Flowers 
sessile and crowded, although solitary in each axil. Calyx thin and membranous, 
rather narrow, about 2 lines long or rather more when in fruit, the lobes scarcely 
so long as the tube. Stamens about 10. Ovary of one carpel obliquely tapering 
into the style, which is rather long and recurved. Ovules about 5 or 6, on 
panicles of various lengths on a short placenta. Capsule acute, circumsciss below 
the middle. Seeds 2 to 5, minutely granulose.

6. T. cypseleoides (Cypselea-like), lienth. FI. Austr. iii. 331. Glabrous, 
prostrate, slender and very small. Leaves obovate or orbicular, scarcely 
above ^in. long in the specimens seen, on slender petioles dilated at the 
base into scarious stipules. Flowers small, in loose axillary pedunculate cymes 
exceeding the leaves, with scarious bracts under the forks and pedicels. Pedicels 
slender, about 1 line long. Calyx about 1 line long, the lobes broad, obtuse, rather 
longer than the tube. Stamens 7 to 10. Ovary of 1 carpel short and rounded, 
with 6 to 12 ovules on funicles of various lengths ; style terminal, but slightly 
excentrical, linear and recurved. Capsule globular, circumsciss. Seeds smooth.

7. MACARTHURIA, Hueg. 
Calyx-segments 5, persistent. Petals 5 or none. Stamens 8, slightly peri- 
gynous, the filaments united in a cup at the base. Ovary free, enclosed in the 
calyx, 3-celled, with 1, 2, or 3 ovules in each cell, attached to a basal placenta ; 
styles 3, with small terminal stigmas. Capsule enclosed in the persistent calyx, 
opening loculicidally in three valves. Seeds reniform or subglobose, the funicle 
expanded into a small cup-shaped white arillus. — Rigid wiry or rush-like herbs or 
undershrubs. Leaves few, alternate, narrow, often all reduced to scales. Flowers 
small, in lateral or terminal short irregular cymes, or forming a spreading 
dichotomous cyme with opposite bracts. 
The genus is confined to Australia. 
1. IVI. neocambrica (N.S.W. species), V. r. M. Fraym. v. 28; Benth. FI. 
Austr. iii. 332. A diffuse plant from a few inches to over a foot broad. Stem 
leaves few, alternate, oblong-linear or linear-cuneate, rather thick. Flowers in a 
loose spreading dichotomous cyme or panicle, each one pedicellate in the forks or
