Has. Abundant in rocky places throughout the Island.—(Fl. Oct., Nov.) (v. v.) 
DisrarB. New South Wales and Victoria, 
A handsome herbaceous plant, 1-2 feet high. Root of thick fascicled fibres, with difficulty removed from the 
soil. Base of stem thickened in old plants, sometimes forming a very distinct bulb. Zeaves linear elongate, terete 
on the back, plane or channelled in front. Raceme 2-4 inches long. Flowers very numerous, on slender peduncles, 
with ovate acuminate scarious bracts at the base. Filaments all with a tuft of hairs above the middle. Capsule 
erect, obovate-globose, with few seeds. 
2. Bulbine semibarbata (Haworth, Revis. 93); radice fibris tenuibus, caule basi simplici, 
racemo laxifloro, filamentis declinatis interioribus supra medium barbatis.—Kunt), En. iv. p. 565. An- 
thericum semibarbatum, Br. Prodr. 275 ; Hook. Bot. Mag. t. 3129. (Gunn, 949.)

Disrr1s. Extratropical Australia, from New South Wales to Swan River. 
A much less handsome plant than 2. bulbosa, with slender fibrous roots, easily removed from the soil, a longer 
laxer raceme of smaller flowers and fruit, and having the filaments bearded above the middle only.

|. Of this genus about ten species are known to me, all of them Australian or Tasmanian. One is 
tropical, the rest inhabit the extratropical quarter, none however being common to the south-east and south-west. 
All are rather slender, white- or blue-flowered herbs, yith roots of fascicled, sometimes tuberous fibres, linear grass- 
like leaves, and a racemose inflorescence.— Flowers jointed on the pedicel. Perianth of six spreading leaflets, 
Stamens six, with naked filaments and small anthers. Ovary three-celled ; cells with from two to four ovules in each. 
Style slender, with a small stigma. Capsule clavate, three-celled, obscurely three-valved, cells one- or two-seeded. 
Seeds with a crustaceous testa. (Named in honour of Frederic Cesius, a botanist of the middle of the seventeenth 
century.) 
§ 1. Flowers corymbose. Ovary with four ovules in each cell. Capsule obcuneate, with four shining compressed 
seeds in each cell. 
l. Czesia corymbosa (Br. Prodr. 277 ) ; parvula, radicibus e fibris tuberosis crassis, foliis planis 
ciliolatis, floribus subcorymbosis erectis, perianthii foliolis late ovatis, filamentis gracillimis, capsula 
obcuneata 4-sperma, seminibus splendentibus. — Kunth, En. Plant. iv. 609. (Gunn, 346.) (Tas.

Has. Abundant in grassy places throughout the Island.— (Fl. Oct.) (v. v.) 
DisrarB. Victoria, 
A charming little plant, conspicuous in grassy pastures from the beautiful blue of its star-shaped flowers, 
Roots of thick, tuberous, fleshy fibres. Leaves flat, plane, linear, rather obtuse, ciliolate, 
longer than the leaves, sparingly branched in a corymbose form above. 
Filaments very slender. Capsule rather membranous, 
2-3 inches long. Scape 
Flowers erect, about 4 inch in diameter.
