vel elliptica vel ovato-oblonga, 1-3 poll. longa, 3-14 poll. lata, 
basi in petiolum 3-6 lin. longum attenuata, obtusiuscula vel

Vavau and Liruxa, W. H. Harvey, 1885; Ovazav, Fiji group,

There are only three species known from Australia, and a fourth, 
which is cultivated all over India and the Malay Archipelago, 
but has never been found in a wild state. As Sir F. von Mueller 
gave the name to Seemann’s specimen without a proper de- 
scription, 1 thought it worth while to describe the plant more 
accurately. It is nearest allied to G. Earlii, F. Muell., which, 
however, is a tree with smaller leaves and a shorter and wider 
corolla-tube and more robust capsules.

Species ex affinitate R. aruensis, 8. Moore, sed fere glabra 
foliis longe petiolatis, bracteolis calycis dentibusque brevioribus, 
corollz tubo subite in limbum patentissimum expanso. 
Herba vel suffrutex ramosus, sesquipedalis (Guppy), cito gla- 
brescens. Folia petiolata, fere membranacea, primum minute 
strigillosa, anguste oblongo-lanceolata, cum petiolo usque ad 
7 poll. longa et 13 poll. lata, obtusa vel subacuta, basi cuneata,
