Tree with white flowers. 
I am indebted to the kindness of Dr. Beccari for a specimen of his 
Gestroa candida, which proved identical with my plant. It also shows with 
the above some flowers with undeveloped ovaries among the more numerous 
% ones. Dr. Beccari wrote that he now considered the plant to be an 
Erythrospermum, and on investigation I am myself inclined to the same 
view.

Jan. 6253. : 
A handsome plant, ‘75 m. high, growing abundantly in large clumps 
along the banks of the stream. Leaves +12 cm. by 4°5 cm., sage-green in 
colour, with 2-3 white spots in more or ess parallel lines between the lateral 
veins, which are conspicuous, 4-5 on each side of the midrib. On the margin 
the largest incisions vary from 1 em. in depth and 1:5 em. in breadth, 
graduating insensibly to the extreme apex. Petiole 1 cm. long. Stipules 
1°5 em. long, often unequal in size, caducous, transparently membranous in 
texture, and produced into long fine hair-like points. g flower 6 mm. by 
7mm. (immature). @ flowers arising singly, opposite the upper leaves, on 
pedicels 1:5-1°8 cm. long, the flowers being 2 cm. long and 3 em. across ; 
with unequal petals, of which the largest are 1:2 cm. by 6°7 mm. ; the three 
styles are bifid, spreading, 5 mm. long. Fruit 1°1 em. long, 1:5 em. across, 
with equal membranous wings, 4 mm. broad in the centre and 5 mm. broad 
at the apex of the fruit. The fruits were affected by insects and swollen out 
of shape in nearly all the plants seen. 
This species is distinct in the very regular and finely graduated serrate 
incisions of the leaves, with their parallel rows of white markings,
