called the Lesser Celandine, which is multiplied 

 enormously by underground buds with tuber-like roots, 

 similar to those of many terrestrial orchids ; but it rarely 

 sets any seed. Such is the case with Disa grandiflo'ra. 



The swollen roots of many of these orchids used to 

 be collected, and a drink made from them called 

 *' Salep," and sold in the streets of London, until the 

 beginning of the last century; but salep has been replaced 

 by coffee. It is still made in the East in Persia. 



Satyr'ium.— This genus has many Cape species, 

 several being cultivated. The lower lip of the perianth 

 is formed by the regular sepals and petals. The upper 

 lip is made of the labellum, which has two spurs or 

 pouches. The anther is bent back, or resupinate, the 

 (rlands being separate and naked. The stigma is two- 

 lobed, the upper lobe being the larger. Many have 

 handsome flowers of an orange, pink, crimson, or 

 greenish colour.

The great majority of orchids of the south-west regions 

 are terrestrial and propagating by means of underground

 Sometimes the bud is at the end of a short branch, so 

 that the new plant which arises from it is at some little 

 distance from the parent plant. Such is the case with 

 Di'sa grandiflo'ra. It is a remarkable fact that all the 

 various kinds of elaborate structures in adaptation to
