long. Flowers solitary or in pairs, with very short pedicels. 
Calyx cup-shaped, shortly lobed, 2 mm. long. Outer petals 
narrow, linear from a broader base, minutely appressed, 
hairy, 6 mm. long, 1 mm. wide. Stamens linear, with a 
very small appendage. Pistils few, silky hairy. 
Sarawak (Beccari, 1908, 3868). 
Very near X. caudata, King, but the flowers are much 
longer and the petals more elongate. 
Alphonsea javanica, Scheff., Flora, liii. 242. 
Sarawak (Beccari, 2621) : Kuching (Haviland & Hose,

I only know this from Scheffer’s description and a flower¬ 
less specimen from Java, but I believe it is the plant 
intended. 
Distrib. Java, Ceran.

Mezzettia Havilandii, n. sp. M. parviflora var. Havilandii, 
Boerh 
Leaves coriaceous, glabrous, elliptic, acuminate; nerves 
eight pairs, thin, inconspicuous on both surfaces, 9-16 cm. 
long, 3‘5-4*5 cm. wide; petiole thick, 5 mm. Flowers 
“ yellow,” in tufts on old wood below the leaves ; pedicels 
1 cm. long, tomentose thinly. Sepals ovate, subacute. 
Outer petals oblong lanceolate obtuse, nearly 2 mm. long. 
Inner petals smaller. Stamens few, rounded. Carpel one. 
Ovules two. Fruit, when dry, about 4 cm. long. Seeds 
one or two, 3 cm. long and wide. 
Sarawak : Kuching (Haviland, 2335). 
This has the foliage of M. parviflora, Becc., but the 
petals are short, not linear acuminate. The species is 
nearest to M. Herveyana, but the leaves are different. 
It is certain that this is what Boerlage means by his 
M. parviflora var. Havilandii, but it seems to me specifi¬ 
cally distinct.
