AA. 
I. U. VULGARIS L. 
Pedicels two to three times as long as 
calyx (7-12 mm.), recurved and re- 
flexed after flowering. 
Corolla upper lip about as long as the 
projecting bilobed palate. 
Lower lip much larger than upper with j 
reflexed margins which scarcely j 
project beyond the palate which is ! 
marked wdth a few separate pale 
red lines. ^ 
Anthers connate. 
Spur adpressed to lower lip. 
Leafy branches often very long, some- 
what coarse. 
Winter buds large (lomm.), nearly 
globular or globular ovoid. 
2. U. MAJOR, Keller. 
Pedicels four to six times as long as 
calyx (12-30 mm.) straight and 
ascending after flowering. 
Corolla upper lip twdce or thrice as 
long as the projecting bilobed 
palate. 
Lower lip with a broad flat spreading 
margin which projects greatly 
beyond the palate, is not reflexed, 
and is marked with chocolate 
brown lines. 
Anthers free. 
Spur conical, sub-compressed not ad- 
pressed to lower lip. 
Leaf branches usually slender. 
Winter buds. 
B I. 
3. U. INTERMEDIA, Hayne. 
Green assimilating leaves, quite without 
bladders. 
Leaf tip obtuse with a prickle set on 
the apical margin. 
Corolla bright yellow, or yellowish 
white, striped with purple, 
subulate, yellow as corolla, as long 
as lower lip to which it is adpres- 
sed. 
Pedicels erect. 
Winter bud after germination retains 
its original ball-shaped or weakly 
elliptical form. The section is 
egg-shaped, obtuse. 
Prickles. The tufts are either situated 
on an extremely reduced leaf-flap 
or directly on its margin. 
I 4. u. OCHROLEUCA, Hartm. 
; Green assimilating leaves, always bearing 
I sporadic bladders. 
I Leaf tip gradually attenuated into a long 
j point which ends with a fine 
^ bristle. 
Corolla, sulphur yellow with brown 
striae. Upper lip flat emarginate. 
Spur conical gradually diminishing from 
a broad base to the blunt apex, 
half as long as and standing apart 
from the lower lip. Red-brown. 
Pedicels patent. 
Winter bud in germination extends to 
more than twice its original length. 
The leaves of the winter bud are 
pointed at the tip, and the inden- 
tation of the leaf margin is stronger 
than in intermedia. 
Prickles. The tufts of prickles at edge 
of bud-leaves are less numerous 
and not so strong as in intermedia 
and are situated upon a distinct 
leaf-flap.
