character of Sarecolobus, R. Br., but they are not ‘apice lateraliter pellucide:,’ as Miquel has it. Dr, See- 
mann takes this for a new genus, and, indeed, as the genera are arranged by Decaisne, it does not accord 
throughout with either Bidaria, Gongronema, or Gymnema proper, while the erect habit is also peculiar, 
ee the two former genera be restored to Gymnema, the present plant could not well be excluded.”-—

A very distinet-looking Hoya has recently been discovered in the Samoan group, viz. H. Samodnsis 
(sp. noy,), Seem.; scandens, glabra; foliis ovato-ellipticis acuminatis 5-tuplinerviis, nervis utrinque promi- 
nulis; corolle lobis extus glabris, intus puberulis. Nomen vernaculum Samoense, “ O-le-Fua-deletla.’—

What I distributed under the name H. pilosa (n, 321) is probably only a young state of this species, 
having the leaves more hairy below,

Perhaps a specimen, without flower, collected in the Isle of Pines (M‘Gillivray), which has leayes twice 
as large as those of my specimens, may belong to this species, of which there are also imperfect specimens 
only.
