LXXIII. CAMPANULACE.E. 



All the species occurring in the district of Pungo Andongo are 

 insignificant herbs and scarcely or not at all conspicuous among 

 other plants ; such is also the case with most of them in Huilla, but 

 Lightfootia collomioides is conspicuous in meadows, while L. ietmi- 

 folia forms an exceedingly pretty heathlike undershrub. Only 

 one of the Huilla species was found to occur also in Pungo Andongo, 

 and that one, namely L. marginata, is very closely related to the' 

 Pungo Andongo L. napiformis, and perhaps might be considered 

 too near for specific distinction. Since, however, the plants are 

 mostly small and rapidly shrivel up, it is quite possible that some 

 of the Huilla species may have escaped notice, since Welwitsch was 

 shut up in the fortress during March and April 1860, and was 

 only on rare occasions able to make botanical excursions.
