or numerous, but rarely more than 3 in a cluster, slender or even filiform 

 striate but less so than in T. anceps. Lower leaves often grass-hke, 2 to 4m. 

 long, the upper ones and sometimes all reduced to short scales. Umbels 

 usually 8 or 4 flowered, the scarious bracts usually prominent and 1 or 2 

 outer ones often produced into subulate points of 3 or 4 lines. Perianth very 

 variable in size, but usually about 4 lines long. Nutlets smaller than in 

 T. anceps. —Bakav in Journ. Linn. 8oc. xv. 362 ; Bauer, lUustr. PI. Nov. Holl.

T. scahra, E. Br. Prod. 278, from Keppel Bay, appears to be a comrBon form of T. clatior, 

 but with a few minute hairs scattered on the lower part ■ of the stem, very different from the 

 hispid T. muricuta. — Benth. 



5. T. simplex (simple), B. Dr. Prod 278 ; Benth. Fl. Austr. vii. 52. Stems- 

 simple or very rarely once-branched, 6in. to 1ft. high, with a few grass-lika- 

 leaves sometimes as long as the stem. Umbel solitary, terminal, with very 

 numerous flowers (usually above 20), the pedicels longer than the perianth. 

 Bracts all scarious or rarely 1 or 2 outer ones with fine points. Perianth- 

 segments about 5 lines long. — Baker in Journ. Linn. Soc. xv. 862.

19. LAXMANNIA, E. Br. 



(After E. Laxmann.) 



Perianth withering and persistent but not twisted, of 6 segments, the 8 outer 

 ones distinct from the base, the 3 inner very shortly united at the base or almost 

 free. Stamens 6, shorter than the perianth, 3 opposite the outer segments 

 hypogynous or nearly so, 8 adnate to the middle of the inner segments ; filaments- 

 filiform ; anthers short, 2-lobed at the base, fixed on the back at the base of th& 

 lobes, the cells opening inwards in longitudinal slits. Ovary contracted at the- 

 base or almost stipitate, 8-celled, with 2' to 4 ovules in each cell ; style shortly 

 filiform, with a somewhat dilated entire stigma. Capsule enclosed in the- 

 perianth,3-valved. Seeds few, black, not flattened, smooth but not shining, without 

 any strophiole. — Perennials with fibrous roots not tuberous. Stems either short- 

 and densely tufted or elongated branched and diffuse. Leaves narrow-linear or 

 subulate, in radical or terminal tufts, dilated at the base into scarious sheathing 

 appendages, which are often produced at the top into simple or wooUy-ciliate 

 bristles. Flowers white or pink, in terminal pedunculate or sessile heads, with 

 imbricate scarious bracts, the outer bracts empty usually entire and forming an 

 involucre usually shorter than the perianths, the inner ones subtending each- 

 flower short very thin and transparent, jagged or fringed on the edge or more- 

 frequently divided to near the base into woolly hair-like segments, sometimes- 

 described as hairs of the rece.ptacle. 



The genus is limited to Australia. 



1. la. gracilis (slender), Ii. Br. Frod. 286 ; Benth. Fl. Austr. vii. 65. Stems- 

 slender, branched, forming loose tufts of 1ft. or more. Leaves crowded at the 

 base and ends of the branches, leaving leafless intervals of -| to lin., the short 

 broad scarious sheathing bases imbricate with a few woolly hairs on their margins,, 

 the blades filiform, erect or spreading, ^ to more than lin. long.. 

 Flower-heads small, on slender peduncles of several inches. Outer empty bracts 

 few, very thin and transparent, ovate, quite entire and glabrous, 1 to 2 lines long ;; 

 inner flowering ones short, more or less fringed with narrow teeth or ciliate with 

 long woolly hairs at the base. Flowers pink, very shortly pedicellate or almost.
