We sometimes see evidence of this in the manner in which the petals of mongrel hybrid plants are finely streaked or blotched with the pure colours of the two parent-forms; and still more plainly in their reversion

According to the ordinary view of each species having been independently created, we should have to attribute this similarity in the enlarged stems of these three plants, not to the vera causa of community of descent, and a consequent tendency to vary in a like manner, but to three separate yet closely related acts of creation. Many similar cases of analogous variation have been observed by Naudin in the

How far these experiments may be trusted, I know not; but the forms experimented on are ranked by Sageret, who mainly founds his classification by the test of infertility, as varieties, and Naudin has come to the same conclusion. The following case is far more remarkable, and seems at first quite incredible; but it is the result of an astonishing number of experiments made during many years on nine species of Verbascum, by so good an observer

above alluded to as varieties, as does a far higher authority, namely, M. Naudin.21 Sageret22 has observed that certain melons have a greater tendency, whatever the cause may be, to keep true than others; and M. Naudin, who has had such immense experience in this group, informs me that he believes that certain varieties intercross more readily than others of the same species; but he has not proved the truth of this conclusion; the frequent abortion of the pollen near Paris being one great

referring to the species of Cucurbita, says, au milieu de toutes les variations du fruit, les tiges, les feuilles, les calices, les corolles, les tamines restent invariables dans chacune d'elles. Yet M. Naudin in describing Cucurbita pepo (p. 30) says, Ici, d'ailleurs, ce ne sont pas seulement les fruits qui varient, c'est aussi le feuillage et tout le port de la plante. N anmoins, je crois qu'on la distinguera toujours facilement des deux autres esp ces, si l'on veut ne pas perdre de vue les

of melons, in which the fruit is so like that of the cucumber, both externally and internally, that it is hardly possible to distinguish the one from the other except by the leaves. The varieties of the melon seem to be endless, for Naudin after six years' study has not come to the end of them: he divides them into ten sections, including numerous sub-varieties which all intercross with perfect ease.143 Of the forms considered by Naudin to be varieties, botanists have made thirty distinct

researches of a distinguished botanist, M. Naudin,136 a flood of light has recently been thrown on this group of plants. M. Naudin, during many years, observed and experimented on above 1200 living specimens, collected from all quarters of the world. Six species are now recognized in the genus Cucurbita; but three alone have been cultivated and concern us, namely, C. maxima and pepo, which include all pumpkins, gourds, squashes, and vegetable marrow, and C. moschata, the water-melon. These three

that of C. maxima and pepo, but when it is elongated the carpels occupy only the terminal and swollen portion. I may add that in one variety of the cucumber (Cucumis sativus) the fruit regularly contains five carpels instead of three.140 I presume that it will not be disputed that we here have instances of great variability in organs of the highest physiological importance, and with most plants of the highest classificatory importance. Sageret141 and Naudin found that the cucumber (C. sativus
