XXIX. SOAPANIA DUMOET. 



Monoecious or dioecious. Inner involucre terminal, com- 

 pressed parallel to the plane of the stem, the apex usually de- 

 curved and the mouth truncate entire or ciliate. Involucral 

 leaves 2, larger and usually more denticulate than those of the 

 stem. Calyptra membranous. Capsule oval. Elaters long, 

 inserted in the middle of the valves, bispiral, deciduous. An- 

 theridia 3-20, in the axils of small saccate leaves which are 

 scarcely imbricate or crowded into terminal heads. Leaves 

 complicate-2-lobed, the dorsal lobe usually smaller. Amphi- 

 gastria wanting. (MARTINELLIA B. Gr. in part.) Name from 

 Gr. skapanion, a hoe or shovel, from the shape of the inner 

 involucre. 



* Lobes of leaves subequal. 



1. S. subalpina Nees. Leaves denticulate outwardly, 

 equidistant, imbricate, bifid almost to the middle, the lobes sub- 

 rotund, obtuse; inner involucre very much longer than the 

 outer, obovate from a narrow base, compressed, truncate, den-
