centre. Anther cells linear. Style slender, little longer than the stamen ; stigma very 
small, hooked. 
The whole inflorescence, about 7 em. long, is narrower and fewer-flowered than that - 
of A. tephrochlamys; the calyx is dark brown when dry, and stiffer in texture than - 
the thin membranous one of that species; the stamen is shorter and more excavate, the 
wings elevated, and running down to join the lip. The lip is almost 3-lobed, the side 
lobes being large and rounded. ‘The whole plant differs much in pubescence, the leaves 
of the fruiting specimen being softly velvety hairy on the back, and those of the flowering 
specimens nearly glabrous. |

Camp III, 2500 to 3100 ft. 
Stem, panicle and fruit crimson, flowers white. This beautiful plant is closely allied 
to Hellwigia pulchra, Warb., differing in the tubular bracts containing only two flowers, 
the glabrous calyx, very short corolla-tube, and the large hairy staminal appendage. 
Like that species, it has the remarkable staminodial teeth on the filament on each side - 
of the anther. |
