Low, who assigns to it the Malay name of “R. Selyan," but his specimen is not 
accompanied by any special indication of locality. 
OssERVATIONs.— | he specimen No. 985 of the Bornean plants consists of portions 
of a male spadix in flower and in portions of radical leaves, which do not differ 
in any way from the corresponding parts of the Javan form. 
The specimen No. 1937 consists of a leaf of an adult plant with its leaf-sheath 
7 cm. in diameter. 
Low's specimen in the Kew Herb. is a less robust plant than those quoted above. 
The leaf-sheath is flagelliferous and auite unarmed. The summit of a leaf is 
terminated by two leaflets connate by their bases, one decurrent or inserted higher 
up than the other.
