LAST week we noticed Mr. Williams's classified enumeration of all the known species of Dianthus. In the present pamphlet he gives Latin descriptions of, and English notes upon, the species of Western Europe. Out of a total of upwards of 200 species, there are altogether 55 in Western Europe, which are distributed through the different countries as follows, viz. 43 in Spain, 33 in France, 13 in Portugal, 7 in Germany, 5 each in Belgium and Holland, and 4 in England. His descriptions seem to be clear and explicit, and he has worked out carefully the geographical range of each species, but he does not give references either to published figures, or, with few exceptions, to the books and papers in which the plants have been originally described. As a rule, he admits species freely, but he unites the common European Dianthus Seguieri with the Chinese and Japanese D. sinensis, which is the parent of many cultivated forms. This gives the species a range from Portugal to Japan. Many of the West European Forms are so puzzling, and the descriptions are so widely scattered, that it will be a boon both to botanists and gardeners to have them all brought together and worked ut on one uniform plan.
