PENTANDRIA— MONOGYNIA. Lithospermum. 255 



Lehman n have observed. Leaves rather narrower than in M. or- 

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

 terminal, leafless stalks, unattended by a solitary distant flower. 

 Partial 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 ; 

 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.

 very short, inserted into some part of the tube. Anth. ob- 

 long, concealed within the tube, Germens 4, inserted into 

 the base of the calyx. Style thread-shaped, shorter than 

 the tube. Stigma obtuse, notched. Seeds 4, ovate, pointed, 

 hard, either even or wrinkled, in the bottom of the mode- 

 rately spreading calyx.
