MONOGRAMME, Schkuhr. 



(Mon-og-ram'-me.) 

 Rush Ferns. 



HIS genus, which forms a small division of the tribe Gram- 

 mitidece, is composed of small grass or rush- like plants with 

 simple (undivided) fronds, and may be said to embrace the 

 simplest in structure of all known Ferns. Though only about 

 nine species are at present known, these are widely distributed 

 over the globe, as representatives of the genus are found in Borneo, at the 

 Cape of Good Hope, in Brazil, in Queensland, e^c. The name is derived from 

 ononos, one, and gramma, writing, in allusion to the disposition of the sori 

 (spore masses), which are arranged in a single row on one or both sides of 

 the midrib of the narrow fronds. In Hooker and Baker's " Synopsis Filicum " 

 Mono gramme forms Grenus 51, and is divided into two sections : 



EuMONOGEAMME (Eu-mon-og-ram'-mc), or Monogramme proper, the fronds 

 of which have a central vein only, and 



Pleueogramme (Pleur-og-ram'-me), Fee, in which the fronds have some 

 indistinct lateral veins in addition to the midrib. 



Culture. 



None of the species contained in this genus are of much value as 

 decorative Ferns ; they are, however, very interesting from a botanical point 

 of yiQw, and three or four of the strongest gTowers may even be used with
