Vincentinum, Ldbg., whose leaves, however, are more distant 

 and more deeply toothed, the stipules oblong, the colour 

 paler, and its size greater.

1 . S. runcinata, Tayl. ; caule csespitoso, erecto, apice incurvo ; 

 foliis incubis, distichis, erecto-patentibus, secundis, stipu- 

 lisque imbricatis, concavis, cordato-oblongis, biiidis, basi 

 margine runcinato-dentatis, segmentis lineari-lanceolatis, 

 canaliculatis, curvatis. 



Hab. Chiloe, Cuming, Hook. Herb. 



Tufts dense, wide, brownish-olive. Stems about 2 inches 

 high, hard, sparingly branched, the branches erect, slightly 

 incurved at the top. Leaves closely imbricated, with a 

 pellucid nerve of a yellower colour than the rest of the 

 leaf, bifurcating and running up each of the segments. 

 Approaching S. juniperina, Endl., a plant far more elongated 

 and slender, with leaves more crowded and narrower, and 

 which are scarcely runcinato-serrate on the margins near the 

 base. 



2. S. pensilis, Tayl.; caule laxe implexo, elongato, subsim- 

 plici, flexoso, pendente ; foliis stipulisque laxis, erecto- 

 patentibus, concavis, integerrimis ex lata amplexante basi 

 subulatis, bifidis, segmentis linearibus canaliculatis, cur- 

 vatis.

Herb. 



Patches hanging from trees, pale yellowish-olive, or reddish- 

 brown. Stems nearly a foot long, waved, sparingly branched, 

 subcompressed. Leaves and stipules rather distant, very 

 brittle when dry, so that the linear segments having been 

 broken off are rarely visible, elongato-subulate, the segments 

 very narrow, and for the most part divergent. The simpler, 

 subcompressed, elongated, waved and pendent stems, and 

 more distant leaves easily separate this from S. juniperina, 

 Endlicher.
