freely. One must never forget this peril. Green 

 fly and thrips also attack them ; but that is a 

 matter of course. 



When the flowering is over, they begin to rest, 

 and it is well to put them in an open frame, in 

 the shade. Much less water should be given. But 

 at all times they must be moist. 



Scarlet is a hue very rare indeed among orchids, 

 but Disa grandiflora shows it. That is the general 

 effect of the blooms, three or four inches in 

 diameter, which crown a leafy spike, one to two 

 feet in length. The number of such spikes which 

 a strong plant will throw up is surprising, and each 

 bears one or two or four flowers in proportion to 

 its vigour. But, in fact, the great side sepals only 

 are scarlet ; petals and lip, insignificant, are orange, 

 and the dorsal sepal, curling over like a hood, is 

 rosy, with crimson veins. It flowers in June and 

 July, lasting for weeks. Table Mountain. 1825.
