 June, July. Cyprus. 

 Very near 7. pallida, 

 from which it differs only 

 by the longer navicular 

 spathe-valves, which are 

 not entirely scarious at 

 flowering-time, and the 

 more obovate segms. 



30. germanica, Linn. 

 Fig. 1968. Lvs. 1-1 Y 2

 short and one longer 

 lateral branch, each
