1. OCULINA HIRTELLA. (Linn.} Lamarck. 



O. ramosa, crassa, ramis inferne inter dum coalitis et scepe 1" crassis, 

 apice J". Corallum, caliculis fere 2'" latis, lamellis valde exsertis et 

 incequalibus, apice truncatis. 



Ramose, stout, branches below sometimes coalescing and often an 

 inch thick, above at apex a fourth of an inch. Corallum with the
