The group angiosperms is thendivided into two classes, the monocotyledones and dicotyledones.(It should be remembered that all systematists do not agree inassigning the same grade and limits to the classes, subclasses,etc. For example, some treat of the angiosperms as a class,and the monocotyledons and dicotyledons as subclasses; whileothers would divide the monocotyledons and dicotyledons intoclasses, instead of treating each one as a class or as a subclass.Systematists differ also in usage as to the termin

We may compare with the case of Acer platanoidesthat of the unsegmented leaf of Caltha palustris. The chief veins radiateoutwards here also from the base of the lamina (Fig. 222), and on themargin of the lamina there are insignificant projections. These arise rela-tively much later than the lobes in the leaves of Acer. The course of theveins depends upon the fact that the lamina which comes off from the thickleaf-stalk

RM2AWKFT3–Children and gardens . it is not at all a tiresome study.Of course botany books in general are apt to be dulland dry and alarming. They frighten one by callingthings names. For instance, they talk about Systemsand Classes; and when you begin with Class I.,Dicotyledones, they expect you to learn that thisclass has four sub-classes, namely : (i) Thalamifiorce,(2) CalyciflorcB, (3) CorolliflorcB, (4) Monochlamydecz, andso on through twenty different classes; all with heavenknows how many sub-classes. Now I dont think that is at all the way to begin,and that is not my botany. But I do want you tol
