 pairs forming the growth of one year, soft and pulpy^ glabronSj ^vhen young

 tapering to a subacute point, slightly concave-channelled or flattish above^ 

 obtusely keeled beneath; the other kind united below into a cylindric body 

 1^-2^ cm. long and 5-7 mm. thick, scarcely distinguishable from tlie stem 

 except in colour, supported on an intornode that frequently does not exceed 

 in length the sheath formed by the pair of leaves at it^ base, with the free

M, cognatum is closely allied to AL divoram^ but it appears to be a dwarfer 

 plant, and Is easily distinguished by its less stout stems, wdiich are thickened 

 at the nodes instead of being constricted there ; its leaves are smaller^ and 

 distinctly united at their base into a cup-shaped sheath a little lonn^er than 

 their own thickness, which is not the case in M. divonim ; they are of a 

 rather lighter greon, with the papillae on them more crystalline, and those 

 on the margins and keel acute and tooth-like, instead of very obtuse.
