254 PENTANDRIA— MONOGYNIA. Lithospermum. 



Lehmann have observed. Leaves rather narrower than in M. ar- 

 vensis. Clusters elevated, either single or in pairs, on long, 

 terminal, Icciiifjss sUilks, unattended by a solitary distant flower. 

 Purtial stalks, even when in fruit, not half the length of the 

 calyx, which resembles that of the foregoing, but its hairs are 

 shorter, and less deflexed. Corolla small ; limb shorter than 

 the tube, blue in the lower half of each cluster, yellow in the 

 upper ; and Dr. Lehmann has determined these colours to be 

 immutable in the several flowers. In some instances the flowers 

 are by him said to be larger, and all yellow, in others all blue j 

 the stigma in the former being somewhat capitate, in the latter 

 slightly cloven. These last particulars have not been noticed 

 in England. They seem to indicate a specific difference. Ca- 

 vanilles may possibly have taken part of his description from 

 M. apula of Linnaeus^ whose synonyms he has applied to our 

 plant, copying them, as appears by his erroneous reference to 

 Lobel, without looking at the books, a practice which cannot be 

 too much reprobated.
