XYRIDACEA. 
The few remarks here offered on the comparative Anatomy 
of Xyridez; affords an additional and strong argument in 
favor of its separation as the type of a distinct order, rather 
than allowing it as at present [1834] to remain associated 
with Restiacez. 
Cuticle. Stomata similarly organised, abound on both sur- 
faces of the leaves and on the peduncles, their communication 
with the interior of the leaf is direct and most evident. 
Leaves. Their whole surface between the cuticles, filled with 
parenchyma, this is traversed by vascular fascicles which have 
no connection with either cutis. 
Parenchyma similarly developed; that contiguous to the
