Grew deals also with the vernation of leaves, and methods of bud protection. He shews that their position and folding gives "two general advantages to the Leaves, Elegance and Security, sc. in taking up, so far as their Forms will bear, the least room; and in being so conveniently couch'd, as to be capable of receiving protection from other parts, or of giving it to one another; as for instance, First, There is the _Plain-Lap_, where the Leaves are all laid somewhat convexly one over another, but not plaited; being to the length, breadth and number of Leaves most agreeable; as in the Buds of _Pear-tree_, _Plum-tree_, etc. But where the Leaves are not thick set, as to stand in the _Plain-lap_, there we have the _Plicature_; as in _Rose-tree_, _Strawberry_, _Cinquefoyl_, _Burnet_ etc." Grew refers also to rolled vernation, distinguishing between the "Fore-Rowl" and the "Back-Rowl." He thus remarks on the hairy covering characteristic of young leaves:--"the _Hairs_ being then in form of a _Down_, alwayes very thick set, thus give that protection to the Leaves, which their exceeding tenderness then requires; so that they seem to be vested with a Coat of _Frieze_, or to be kept warm like young and dainty Chickens, in Wooll." In the year following the publication of _The Anatomy of Vegetables Begun_, Nehemiah Grew produced a second treatise, under the title, "An Idea of a Phytological History Propounded. Together with a Continuation of the Anatomy of Vegetables; Particularly prosecuted upon Roots. And an Account of the Vegetation of Roots Grounded chiefly thereupon." In the dedications of his books Grew often reveals much of his own personality, and of his attitude towards science, although such revelations are apt to be mingled with the curious "conceits," and extravagant flattery, characteristic of the time. For instance he dedicated this particular work to the President and Fellows of the Royal Society, and after addressing to them some apologetic remarks about his own performance, he takes heart of grace from the thought that "how unpromising soever the Stock may be, yet the Fruit cannot but be somewhat matured upon which You are pleas'd to shine." It shews how strong the influence of fashion can be, when we find such bombast coming from the pen of a man who, only a few lines earlier, has written, with the perfection of simplicity, "Withal, I looked upon Nature as a Treasure so infinitely full, that as all men together cannot exhaust it; so no man, but may find out somewhat therein, if he be resolved to try."
