specimens are not at all reduced at the apex of the lamina; the 
other smaller forms are but slightly reduced at the apex. 
Kaulfuss described L. Ryani from Montserrat Island, saying 
he had seen only young specimens. Despite the reddish woolly 
character of both surfaces, it probably belongs with striata, from 
which he separates it because of oblong, smooth tubercles on the 
rachis at the base of the petioles; the lower, bipinnatifid, fertile 
pinnae suggest that he had an abnormal frond.* Raddi describes 
his L. brasiliensis as intermediate between lineata and striata. 
In the shape of the blade and in the small number of pinnae it 
Seems nearer the smaller .S. striata plants.
