FLORULA HONGKONGENSIS. 297 
a mere variety, more rigid in habit and foliage. The number of cells 
of the ovary is usually five, as in the Dahurian plant; the position 
of these cells with relation to the calyx is still uncertain, and there 
are scarcely sufficient characters to separate Platycodon generically from 
the larger-flowered Wahlenbergia.

Rice-fields, in March. Flowers pale blue. Some of Dr. Wallich’s 
Silhet specimens distributed as Campanula (Wahlenbergia) dehiscens, agree 
precisely with our plant, but belong probably also to the W. agrestis, 
which only differs from W. dehiscens in having narrower leaves, and 
blue, not white, flowers.

Rocks on the sea-shore, growing gregariously in large masses. 
Flowers in July. Brown (Prodr. p. 582) had already indicated the 
absence of any distinguishing character between S. Lobelia and S. seri- 
cea except the pubescence, which subsequent experience has shown to be 
very variable. De Vriese, who has since worked up the genus with great 
detail, has proved the identity of the common maritime species of the 
New World (S. Plumieri) with that of the Old World, and it is now 
evident that not only the several forms collected under one species by 
Hance (Walp. Ann. vol. ii. p. 1055), but also the S. Plumieri, S. Thun- 
bergii, and S. Senegalensis, are all varieties of one widely-spread mari- 
time species, for which however the old Linnæan name adopted by De 
Vriese, S. Lobelia, is quite sufficient, without the coining of the new 
one, S. latevaga, proposed by Hance,
