DISA DRACONIS. 
White and dark blue. 
DISA GRAMINIFOLIA. 
Bright blue, the lip being striped with alternate narrow bands of white and mauve. 
DISA UNIFLORA. . 
Lateral sepals crimson, dorsal sepal bright pink outside and bluish inside, with 
crimson veins, the petals brilliant scarlet as is also the lip. (Syn. D. grandiflora.) 
Var. Superba. Flowers very large and much the same colour as the type, but the 
crimson sepals are tinged with orange. 
DISA RACEMOSA. 
Sepals rose pink with deeper pink veins, petals and lip scarlet and yellow. 
DISA TRIPETALOIDES. 
Flowers smallish. Pinkish white, dotted with rose-purple. 
The flowers of the species are attractive in form, the dorsal sepal usually being 
hooded or helmet-like in shape—the lateral sepals being broad and spreading, while 
the petals and lip are much smaller, the latter being narrow, acute, and projecting 
forward. 
DIURIS 
A genus of small, terrestrial orchids found in the coastal districts of South 
Eastern Australia. They are attractive in form and colouring, but are not 
suitable for general culture in orchid collections. The plants are usually slender 
and from several inches to 2 feet in height with a few narrow and comparatively 
long leaves. The flowers can generally be identified by the two long, narrow, 
downward lateral sepals which give them their popular name of “two-tails.” 
They grow from a small underground tuber which is sometimes quite a distance 
below the surface of the soil—and, moreover, they seem to delight in getting 
under a rock which makes it particularly difficult to remove them without 
injury. I managed to flower two or three species by planting them in their native 
soil and growing them in a shallow pan in a sunny place—giving them ample 
water from the time the first shoots appeared. There are about 30 varieties of 
which the following are best known:— 
DIURIS ABBREVIATA.
