sessile, rigid, thick, ovate-oblong or lanceolate, the largest about | in. 

 long, equalling the internodes, rather obtuse, entire or furnished with a 

 pair of small teeth near the middle, setulose, especially on the margin 

 and midrib on the underside. Flowers solitary in the axils of the oppo- 

 site leaves or bracts, very shortly pedicellate ; floral-leaves or bracts 

 shorter than the flowers, similar to the leaves ; bracteoles linear- 

 lanceolate, about 2 lin. long, setulose. Calyx hispid, about ^ in. long, 

 10-ribbed, nearly equally 5-lobed ; lobes oblong, obtuse, shorter than 

 the tube. Corolla about \ in. long, narrow-cam pan ulate, constricted 

 close above the ovary ; lobes very short, rounded, notched. Stamens 

 nearly equal ; filaments filiform, bearded close under the anthers ; 

 anther-cells almost equal, mucronulate.

Our specimens are evidently full length, as one at least lias roots, but they may 

 he from starved plants, and the normal dimensions may be larger. 



16. A. aurantiaca, Hemsl. An annual, parasitic herb, rough 

 with warted or tubercled bristles, interspersed with softer hairs, 2-4 in. 

 high, branching from the base. "Primary stem subterranean, bright 

 orange in colour " ; branches slender, alternate. Leaves crowded, 

 apparently all alternate, sessile, rather thick, narrow-lanceolate or 

 spathulate, the longest about 1 in. long, obtuse tapering to the base, 

 few-toothed. Flowers shortly pedicellate, yellow, solitary in the axils of 

 the upper leaves or bracts, about f in. long ; bracts similar to the 

 leaves, longer than the flowers, smaller upwards, adnate to the base 

 ■of the pedicel ; bracteoles linear, acute, about £ in. long, thinly clothed, 

 as well as the calyx, with long soft hairs. Calyx thin, about ^ in. 

 long, 10-nerved, nearly equally 5-lobed ; lobes triangular, scarcely 

 acute about as long as the tube. Corolla obliquely campanulate, about 

 a in. long, veined, 5-lobed ; lobes rounded. Stamens nearly equal ; 

 filaments all bearded, the longer very strongly ; anther-cells slightly 

 unequal, apiculate. Ovary glabrous ; style longer than the stamens, 

 elub-shaped above the middle, strongly recurved. — Bopusia scabra,

This has the characters of Alectra, including yellow flowers, a marcescent, per- 

 sistent corolla, and a clavate, recurved style. Bopusia scabra, Presl (Graderia 

 scabra, Benth.), also differs in being perennial and woody at the base and in having 

 pink flowers and a deciduous corolla. 



17. A. trinervis, Hemsl. An erect, hispid, not tuberculate, herb, 

 $-15 in. high. Stems slender, weak, simple or forked. Leaves opposite, 

 except in the inflorescence, distinctly stalked, rather thick, ovate or 

 oblong-lanceolate, or the lowermost smaller and nearly orbicular, largest 

 scarcely 1£ in. long, obtuse or rounded, entire or with a few small teeth, 

 3-nerved, hispid on both surfaces. Flowers few, shortly pedicellate, 

 about £ in. long. Bracts or floral-leaves ovate-oblong, mostly as long 

 as the flowers. Bracteoles shorter than the calyx, linear. Calyx softly
