denly reflected a little below the apex, and terminate in a 

 short pulvinate connective, to which the 2 anther lobes are 

 attached, these being somewhat divaricate at base. The pollen 

 (like that of Cestrum organense), is compressed, trigonous, 

 with a small rounded lobe at each angle, from which 3 con- 

 vergent lines meet in the centre. The ovarium is obovate, 

 shining, stipitate, and invested at base by a free fleshy disc, 

 consisting of 2 broad lobes, arising from the stipes : (in F. ini- 

 bricata these lobes are narrow, opposite, quite separate, and 

 erect). The style is filiform, as long as the stamens, incurved 

 towards the summit, where it is considerably thickened ; the 

 stigma is thick, clavate, oblique, with two rather reflected 

 lamellar lips. The capsule is cylindrical, about 5 lines long, 

 and 1 \ line diameter, invested at base by the persistent calyx ; 

 it splits into 2 valves, the margins of which are deeply intro- 

 flected, and the summit of each valve is cleft about one- 

 fourth of its length : the placentary column is placed trans- 

 versely with the valves, and shows a number of small projec- 

 tions arranged in longitudinal series, which have been the 

 points of attachment of the seeds. The seeds are numerous 

 and small, oval, rounded on the dorsal side, and angular on 

 the ventral face, the hilum being here situated a little above 

 the middle. The embryo placed in the centre of fleshy albu- 

 men is linear, almost straight, or very slightly sigmoid, the 

 radicle is terete, with cotyledons one-fourth of its length, 

 which are equal to it in breadth, and slightly compressed. 



I may here remark, that the Fabinna lanuginosa, Hook. 

 Am. Bot. Beechy's Voyage 35, is the Dolia vermiculata, Lindl. 

 (see Vol. 4. p. 502). As the plants collected in that expe- 

 dition offered no specimen in seed, there was every reason 

 for considering it to be a Fabiana, the flower and the habit of 

 which it so much resembles, rather than the type of a new 

 genus among the Nolanaceee. 



NlEREMBERGIA. 



I have already offered some reasons (p. 147) for showing why 

 this genus, hitherto considered as belonging to Nicotiane#>
