To quickly assess the difficulty of the text, read a short excerpt:
As already mentioned, the winding to the right occupies the upper part, that to the left the lower part of the fruit-stalks of Mosses. The winding fruit-stalks of the Mosses are further distinguished from the leaves of Vascular plants by the circumstance that in the latter the upper winding is developed before the lower, while in the former the lower is shown before the upper. Since then the lower winding of the fruit-stalk of the Mosses is directed to the left and the upper to the right, the w...inding to the left precedes that towards the right here also. The only exception to this occurs in the fruit-stalks of the Funariece, which wind to the right below and to the left above ; and in these, therefore, the winding to the right precedes that towards the left. 52. A similar relation to that just demonstrated between the winding to the left and right and the earlier and later, or upper and lower parts of the leaf, may perhaps be assumed of the windings which derive their determination from the direction of the leaf-spiral, either in the positive or negative sense.
