284 MR. R. A. ROLFE ON THE APOSTASIER. 
Leaves 8-18 in. long by 13-22 in. broad. Scape much shorter 
than the leaves. Racemes 4—5 in. long. Bracts 9-12 lin. long 
by 11-22 lin. broad. Pedicels 2 lin. long. Ovary 23 lin. long. 
Segments 5-6 lin. long. Column and free portion of filaments 
each about 1 lin. long. Style 2 lin. long. 
The leaves are broader and the racemes shorter than in 
any of the preceding species, while the pubescence is also very 
marked. The Penang plant seems quite identical with the Su- 
matran one. In this latter two or three of the flowers I have 
examined are monstrous, while others are in the normal condition. 
In one the two lateral sepals and the lip occur in their normal 
position, the dorsal sepal and the two petals being carried at least 
a line higher by a pedicel-like growth formed of their united bases 
together with the column. After elongating for another line the 
style becomes free, while the filaments remain further united for 
over half a line more, when they branch in the ordinary way, the 
central filament being, as usual, a little longer than the lateral 
ones. This condition is represented on Pl. XLVIII. fig. 13. It 
appears to result from a remarkable lengthening of the floral 
axis. All the organs appear to be quite perfect. In a second 
flower, however, the petals are united to the lateral sepals, while 
the filaments are wholly connate. In other respects the flower 
is unaltered.
