60 Some hitherto unknown Australian Plants. 



Bidaria leptophylla. 



Climbing; branchlets slender as well as the peduncles covered 

 with velvet hair; leaves linear, slightly downy; pedun- 

 cles as long as the umbel ; corolla small, urceolate ; its 

 teeth blunt, three times shorter than the tube. 



At the sources of the Burdeken River. 



A milky plant, several feet high. Stems terete, sometimes 

 rather silky. Leaves acute, opposite or, through imperfect 

 development of the branchlets, fsesciculate, at last glabrous, 

 1^-2 inches long, 1-2 lines broad, with flat margin. Umbels 

 with several or many flowers, solitary or twin. Peduncles 

 half an inch long or shorter. Pedicels longer than the linear- 

 subulate unequal bracteoles. Calyx with fine appressed 

 downs, scarcely longer than one line ; its lobes lanceolate, 

 acute, appressed. Corolla 2^ lines long, outside glabrous ; 

 tube ovate ; inside with a line of hair ; limb spreading only 

 half a line long with orbicular- ovate blunt lobes. Anthers 

 terminated in a white membrane. Stigma white conical. 



ScROPHULARINjE. 



Vandellia clausa. 



(Sect. Bonnaya.) 



Glabrous ; stem simple, erect, producing leaves only at the 

 base, sometimes with a pair of small bracts near the 

 middle ; leaves broad-ovate, repand or denticulate, the 

 lower ones the smallest ; racemes terminal, solitary or 

 twin, with several or many flowers ; bracteoles solitary, 

 or the lower ones opposite, lanceolate or linear subulate, 

 several times shorter than the pedicels - the latter twice 

 to four times as long as the calyx, and about as long or 

 not much longer than the capsule ; calyx deeply five- 

 cleft, with linear-subulate segments ; tube of the corolla 

 nearly cylindrical, almost three times as long as the 

 calyx; faux closed; sterile stamens totally adnate, form- 

 ing two slightly prominent carinas ; anthers of the two 

 fertile stamens one-celled, coherent; capsules linear- 

 elliptical, rather acute, longer than the style ; seeds 

 black, nearly ovate, angulate, transversely streaked. 



On sand-plains, subject to occasional inundations, on the 

 Victoria River and its tributaries.
