A IR A  PRÆCOX.  {$«. p ^ ‘- 
 Unexpanding Hair-grass. 
 Spec. Char. Panicle  upright,  rarely expanding; leaves fine,  short,  and setaceous. 
 This  out  most diminutive Aira  inhabits  situations  similar  to,  and is often  found  associating  with,  
 the preceding species,  but  is  rather  an  earlier plant:  it is chiefly observable by its  small  and almost  
 spike-like panicle,  which hardly ever manifests  ally tendency to expand or become divaricated in that  
 temate  maimer,  so  remarkable  in the  larger Aira caryophyUea,  to which species  it  is  nearly allied.  
 —— Of  any utility at present  attached to,  or likely to be derived from,  this little vernal Hair-grass,  
 we  are perfectly ignorant,  and perhaps constituting a species in the herbarium of the collector may be  
 the only notice it is calculated to obtain:  the botanist bestows upon it a rank,  and marks  a  character,  
 that it can but slightly claim from intrinsic value or apparent virtue. 
 A,  a Floret. 
 B,  the Calyx. 
 C,  the Corolla.
