DICRANACE^;.] 102 [Swcirtzia 



4. SWARTZIA EHRHART. 



(PI. crypt, exsicc. n. 164 (1787). ) 



Plants in dense silky tufts ; slender, fastigiate, dichotomous. Leaves 

 distichous, spreading from a semiamplexicaul base, subulate, smooth ; 

 areolation hexagono-rectangular at base, narrow and quadrate above. 

 Calyptra cucullate. Capsule erect or cernuous, glossy, ovate or cylin- 

 draceous; lid conic. Teeth 16, not confluent at base, lineal-lanceolate, 

 irregularly separated at the divisural line, or variously torn or perforated. 

 Spores smooth. Inhabiting rocks or the ground. Deriv. Named in 

 honour of Olaf Swartz. 



The close alliance between this genus and Ditrichum flexicauk will be 

 seen at a glance, yet Schimper makes it the type of a distinct family, on 

 account of the distichous leaves. The name Swartzia was adopted by 

 Schreber in 1791 for a genus of Leguminous plants, but it will be seen that 

 Ehrhart's name has four years priority, and therefore Schreber's genus must 

 not only give way to Ehrhart's but stand under its older designation of 

 Tounatea AUBLET (1775.)
