THE SCITAMINEZ OF THE MALAY PENINSULA. 189 
Distinct in its narrow grassy leaves, and very small flowers. 
A. macrodus Scot. Nuov. Giorn. Bot. Ital. xviii 809 from 
the Kinta Valley, Perak, has well developed staminoles, and a 
simple anther crest. Itis perhaps a Gastrochilus. I have never 
met with it. 
HORNSTEDTIA. 
This genus was founded by Retz ( Observationes iii. ) on the 
two common species of the peninsula 7. scyphus and H. Leonurus. 
Later Blume described some species under the name of Donaco- 
des. others he referred to the genus WHiettaria. Griffith over- 
looking Retz’ work, made two genera Stenochasma and Achasma, 
and finally they were all placed under Amomum by Bentham and 
Hooker, who was followed by Baker. I propose to restore Retz’ 
genus and to include also under it the beautiful plants classed as 
Pheomeria Lind). and Nico/aia Horan. The genus thus may be 
described. Plants with tail rarely short leafy stems, often 12 to 
15 feet tall. Leaves numerous oblone petioled. Spikes radical 
on short or long peduncles, with large outer bracts usually red, 
ovate or oblong, forming a cup or spreading. Bracteoles thin 
tubular. Flowers sessile numerous. Calyx spathaceous thin, 
Corolla long or short-tubed, lobes oblong narrow not spreading, 
Lip narrow often Jong, linear or narrowly oblong, the sides at 
the base convolute over the stamen. Stamen short and _ thick, 
anther fleshy, bent at an angle with the filament, crest very 
small or none. Staminodes none. Capsule oblong with thin 
cartilaginous walls and numerous black seeds, or (section Pheo- 
meria) sub-globose with a green fleshy pericarp and bony walls 
and brown angled seeds. Species about 20 known, scarce in 
India abundant in the Malay peninsula and the Western part of 
the Malay archipelago. 
Section 1. Hu-hornstedtia, Spikes on very short peduncles 
buried in the ground. Tube of flowers very long, lip long. Fruit 
concealed in the persistent outer bracts, thin-walled oblong. 
Section 2. Pheomeria. Spikes on tall peduncles, cone- 
shaped or cup-shaped. ‘Tube of flowers and lip short. Fruit glo- 
bose woody the outside green and fleshy, arranged in a ball, the 
bracts having disappeared. 
To the former section besides those of the Malay peninsula 
belong Alpinia linguiforme Roxb. of India, and apparently from
