TropicaL Arrica. Abyssinia: a January 1909, Dr. Drake- 
Brockman, 187, 188, 189, 190, 191, 
The plant has been identified from Lindau’s description of the type 
specimens collected by Riva at Dschacorsa, Somaliland. Although 
the striking morphological features are in agreement, there are several 
slight discrepancies. For instance, the style of the type is stated to be 
27 mm. long, that of the Abyssinian plant is 45 mm. long. Again, the 
calyx-segments are described by Lindau as being 30 x 7 mm., those of 
Drake-Brockman’s plant average 21 xX mm. 
The small glands (which in the dried specimens appear as hya- 
line scales) found on all the parts with the exception of the old 
wood are in agreement with the general xerophytic habit of the 
plant. The calyx-segments (as in other species of the genus) 
are connected by a delicate membrane. When dried calyces are 
boiled the segments immediately separate to the very base. The 
reduction of the anticous petal to a thickened spur is remarkable. 
The filaments are united in a peculiar manner. One anticous and 
one lateral filament unite to form a comparatively broad membrane 
the second lateral one to form a second membrane unilaterally 
adnate to the corolla tube. This arrangement gives the appearance 
of a staminal tube split down one side and attached on the opposite 
side for its whole length to the corolla tube. The disc is represented by 
a narrow ring of tissue (hardly distinguishable from the receptacle and 
pe 15 mm. high, as crete by Lindau for the Somaliland specimens), 
m the inside of which on the posticous side arises a slender spur 
cae half the length of ea ovary. The backs of the anthers and the 
ovary are densely covered with glandular scales—W. B. TurRILL
