XLYII. DROSERACE^E. 
551 
lamina of line diameter, on a petiole of 1 to 2 lines, the upper ones twice as 
large or rather more. Stipules to some of the upper leaves very thin, narrow, 
scarious and deciduous. Flowers few, small, in a simple raceme like the smaller 
specimens of D. peltata. Pedicels nearly as long as the calyx. Sepals villous, 1 
to 1^ line long. Petals spreading, longer than the calyx. Styles 3, divided to 
the base into 2 deeply 3-fid branches. — Planch, in Ann. Sc. Nat. ser. 3, ix. 291. 
Hab.: Endeavour River, Banks and Solander. 
2. ALDROVANDA, Linn. 
(After Ulysses Aldrovandus.) 
Calyx 5-partite. Petals 5, hypogynous, connivent in a cap. Stamens 5, 
hypogynous. Ovary 1-celled. Styles 5, with terminal branching stigmas; ovules 
numerous, on 5 parietal placentas. Capsule globose, 5-valved. Seeds numerous, 
broad, oblong, testa black, shining. — A weak succulent diaphanous glabrous 
floating herb in water. Stems articulate, with whorls of spathulate-orbicular 
leaves at the nodes, the laminte li to 3 lines diameter, contorted, bladdery. 
Flowers pedunculate, axillary, solitary. — S. B. Clarke in Hook. FI. Brit. Ind. 
ii. 425. 
A genus of a single species found growing in still water in central Europe and East India> 
besides Queensland. 
1. A. vesiculosa (bladdery), Linn.; DC. Prod. i. 319. A swimming and 
submerged glabrous plant, stems elongate, branching. Leaves verticillate, 6 to 9 
in a whorl, inflated at the end so as to form a vesicle. Petiole flat with 4 or 5 
bristles at the extremity. Flowers white, solitary on a long slender axillary 
peduncle. 
Hab.: Swamps about Rockhampton, P. O’Shanesy (F. v. M. Fragm. x. 79). 
3. BYBLIS, Salisb. 
(After Byblys, the daughter of Miletus.) 
Calyx-segments or sepals 5. Petals 5, broad, oblique, united in a ring at the 
base, contorted-imbricate. Stamens 5, hypogynous, often declinate ; anthers 
attached by the base, opening at the end in oblong pores or short slits. Ovary 
2-celled, with several ovules in each cell attached to the dissepiment ; style 
undivided, with a terminal oblong or capitate stigma. Capsule somewhat com- 
pressed, 2-celled, opening in 2 valves, bearing the dissepiment in their centre. 
Seeds oblong, albuminous. Herbs, more or less glandular-pubescent. Leaves 
linear-subulate, involute in vernation, without stipules. Peduncles axillary, 
bearing a single blue flower. 
The genus is limited to Australia. It is very anomalous in the Order, with which it is chiefly 
connected by the glandular pubescence and the leaves involute in vernation. The flowers, 
especially those of B. gigantea (W. Australian species), have a remarkable resemblance in 
structure to those of Cheiranthera in Pittosporea. — Benth. 
1. B. liniflora (Flax-flowered), Salisb. Parad. Lond. t. 95 ; Benth. FI. 
Austr. ii. 470. Glabrous or viscid with a glandular pubescence, sometimes 
copiously so. Stems slender, rarely Gin. high and often only 2 or Sin. Leaves 
filiform, 1 to 2in. long. Peduncles slender, usually exceeding the leaves. Sepals 
lanceolate, acute, 2 to 3 lines long. Anthers varying from f line to 1), line in
