(2) A. speciosa Bl. Bijdr. 401, t. 73. A. Philippii Rchb. fil. 
var. malayana Ridl. Mat. i. 124. 
Stems very slender, 3 ft. long or even less. Leaves linear 
acuminate, 4 to 6 in. long, -25 in. wide. Flowers much smaller 
than in A. bambusifolia, about 1 in. long, pale pink to white, with 
the lip only mauve at the tip with distinct central yellow bar. 
Sepals lanceolate, -2 in. wide. Petals lanceolate-ovate acute, 1 in. 
long, *5 in. wide. Lip rather narrow, *5 in. wide at the tip; keels 
two. Capsule 2 in. long. Hab. Not common. Kedah Peak on 
precipices (a form with brown streaks on sides of lip and dark 
crimson tip). Setul (Haniff); flowers nearly white, lip tip pale 
mauve. Dtslrib. Java, Burma. 
This is commonly cultivated in Singapore, producing bulbils from the 
stem. It has run wild or been planted on rail-banks near Kwala Lumpur, 
Negri Sembilan and other places. The Hongkong plant commonly cultivated, 
distinguished by its very deep crimson tip to the lip, is probably Blume’s 
chinensis, which is described, however, by him as having five ribs on the lip, 
which I have never seen in any Arundina flower. It is also the A. Philippii 
and Meyenii of Rchb. fil. It is closely allied to A. speciosa, but besides the 
deep-coloured apex of lip, does not produce bulbils, as that species does.
