ferable. The main rib is flattened beneath, so as to be qua- 

 drangular ; the leaflets are more generally alternate, more 

 wedge-shaped at their base, somewhat pointed, and more deeply 

 crenate, than in the common species. The capsules are rather 

 paler, of a more yellowish, rusty hue.

 several, erect, firm, oblong-lanceolate, from three to nine inches 

 high, of which, the dark-coloured naked s<a/A: commonly makes 

 one-third, or nearly so. The midrib has a thick, but not broad, 

 border. Leaflets several, dark green, mostly alternate, some- 

 what stalked, of an irregular, oblong, obtuse, somewhat ovate 

 figure, seldom an inch long ; the base wedge-shaped, broadest, 

 and often extended into a lobe, at the upper edge ; the margin 

 more or less crenate, or cut, throughout ; the upper ones de- 

 current and confluent. Masses several, obliquely transverse, 

 linear, obtuse, occupying the whole back of the leaflet, but not 

 crowded, nor confluent j those towards the extremity very 

 short. Cover uninterrupted, even, of a pale brown, opening 

 towards the midrib of each leaflet. Capsules chesnut-coloured,
