XCV. SELAGINE^. 



This family, which is abundantly represented in the Cape flora, 

 was previously to Welwitsch's discoveries unknown in West 

 Tropical Africa ; the three species which were found in Huilla are 

 among the most delightful of its plants, and embellish those high- 

 lands with indescribable charms. The negresses, w4io are in general 

 but little susceptible to the beauties of nature, are in the habit of 

 weaving in their head-dresses the flowering branches of the two 

 following species of Selago, or stick them behind their ears, as they 

 carry goods to the market at Lopollo.
