dense hispidula; foliis ovalibus superne lanceolatis acuminatis ; 
spica usque pedali, densa; bracteis anguste lanceolatis acutis 
pedicellos equantibus vel sepissime superantibus ; sepalis late- 
ralibus patentibus (?) oblique ovatis 3-nerviis, apice crassiusculis 
integris, dorso minute pubescentibus, dorsali ovato simili sed 
haud obliquo cum petalis supra antheram connivente ; petalis 
oblongis 1-nerviis vel partim 2-nerviis obtusis integris ; labelli 
lumina triloba, lobis rotundatis basi breviter rotunde saccata, 
lateralibus medio duplo longioribus, calcare scrotiformi 1-lineari 
alto; anthere loculis paralielis basi haud divergentibus apice 
rotundis, connectivo haud prolongato, glandulis nudis contiguis 
sed rostello intermedio in processum subulatum breviter con- 
tinuato. 
Hab. Nyasaland, 1891: Buchanan, no. 572. 
The plant, which is 20inches or more in height, is covered with 
very short stiff brown hairs; the leaves are 14 inch long and 
3-5 lines broad, the dense spike reaches a foot in length, and the 
narrowly lanceolate pointed bracts are equal to or longer than 
the flower-pedicels. The obliquely ovate lateral sepals are 
35 lines long by 2 lines broad; the dorsal, 3 lines by 12, meets the 
lateral petals above the anther, these being oblong, 2} lines long 
by 15 broad. The lip broadens rapidly from a narrow base, and 
is 4 lines long by 4 lines at its broadest anteriorly, where it is 
3-lobed, the lobes rounded, and the central one half the length of 
the two lateral. The scrotiform spur is 1 line deep. 
Var. minor. Planta minor pedalis foliis ovalibus acuminatis ; 
spica semipedali; bracteis pedicellos squantibus quam folia 
minoribus, iis autem similibus vel magis lanceolatis; florum 
partibus quam in typo minoribus. 
Hab. Woods on hills N.E. of Kariandusi, east of camp 44, 
7000 ft.: J. W. Gregory, May 9, 1893. 
Differs from the type in the smaller size of the plant, which is 
11-183 inches high, with more oval broader leaves 14 line long 
by 5-6 broad. The dense spike is 6 inches lon 
g, while the parts 
of the flower are also smaller. The lateral sepals measure 3 lines 
by 12 
%, the dorsal 2 by 14, the lateral petals 2 by 1, while the lip is 
34 lines long and barely 4 across.
