36 THE ORCHID REVIEW. (FEBRUARY, 1910. 
and a few other species are occasionally seen in cultivation. They are 
Orchis-like in habit, with dense-flowered spikes, and the lip is remarkable 
for being superior, and galeate, with two, often elongated spurs, sometimes 
reduced to short sacs, at the base, and the sepals and petals are arranged 
something like a fan beneath. The column is rather complex, and is 
situated within the mouth of the galeate lip. Over sixty species have been 
described, and the colour of the flower varies from green to white, yellow, 
orange, pink and carmine. Practically nothing is known about the fertilisa- 
tion of the flowers. 
In the genus Disa it is the dorsal sepal which is the upper galeate body, 
the lip being situated beneath, and often very small and narrow. The 
dorsal sepal is variously spurred behind, this part being sometimes very 
short, at others much elongated and narrow. The petals are usually situated 
within the dorsal sepal, and are often very curiously shaped, while the 
column and appendages are very complex in structure. There are several 
small genera closely allied to Disa, which are sometimes included in it, as 
Monadenia, Herschelia, which includes the beautiful ‘‘ blue Disas,” with a 
fringed lip, or in two cases the limb carried on a much elongated stalk, 
Schizodium, and Brownleea, and together they aggregate over 100 species 
the majority being South African, with several others in adjacent regions of 
tropical Africa, and a few in Madagascar. A few species are well known in 
cultivation, the most popular being the magnificent Disa grandiflora, the 
Queen of terrestrial Orchids in the Southern hemisphere, popularly known as 
**The Pride of Table Mountain,” and so much sought after that the 
Government has had to intervene and restrict the removal of the tubers to 
reasonable limits. The species of Disa vary much in the size, shape, and 
colour of the flowers, and very little is known about the insects which 
fertilise them. 
The small subtribe Coryciez is also chiefly African, but a few species of 
Disperis are found in tropical Africa, the Mascarene Islands, Ceylon and 
South India. The group contains four genera and about seventy species- 
It is characterised by having the lip adnate to the face of the column and 
extended beyond the widely separated lobes of the anther into a variously- 
shaped appendage. The anther is usually reflexed, and the stigma bilobed.- 
in short the flowers are very complex in structure. In Disperis the lateral 
sepals are saccate or spurred behind. The group is rarely represented in 
cultivation, and practically nothing is known of the fertilisation of the 
flowers. 
This concludes our review of the Ophrydez, and our next paper com- 
mences the Epidendrez and the great epiphytic division of the family.
