Differs from V, isotjensis (which is a tree) in habit, in the 

 leaflets more markedly cuneate at the base, in the longer bracts, 

 the relatively narrower but longer calyces with larger acute lobes, 

 and the longer heliotrope corollas with somewhat different lobes. 

 Among other points it is easily distinguished from V. Hildebrandtii 

 Vatke by the narrow tube of its corollas.

SEED-PRODUCTION IN VIOLETS. 



By E. S. Gregory. 



An erroneous impression prevails amongst botanists with re- 

 gard to the seed-bearing qualities of the open early flowers of the 

 Nonimium section of British violets. It has been generally admitted 

 that an occasional cross has happened (otherwise how could hybrid 

 violets exist?), but the serious business of producing fertile seed 

 has been relegated to the cleistogamous or later flowers, which 

 must, of necessity, be self-fertilized. In cases where these violet 

 plants are deprived of the sun's rays, it has been proved that no 

 open flowers are produced; under these conditions, however, abun- 

 dant seed is furnished by the very numerous though inconspicuous 



later flowers.

If these 



blossoms are visited by hive or humble bees they are cross-ferti- 

 lized ; but many are not thus visited, and their fate is then to 

 wither without effecting that process of autogamy which has been
