If now the clover increases its number of leaflets, this may be considered as a reversion to its nearest progenitors, the papilionaceous plants with pinnate leaves. Hence a halfway returning and therefore positive atavism. And as I have already mentioned in a former lecture, pinnate leaves are also sometimes produced by my new race of clover.
It is, as a matter of fact, remarkable that it has not taken place in more numerous instances, and the mallows show that such opportunities have been available at least more than once. Other instances of taxonomic anomalies are afforded by leaves. Many genera, the species of which mainly bear pinnate or palmate leaves, have stray types with undivided leaves.
"The next is this unusual-looking pinnate leaf." He tore off a dry leaflet and handed me a stem with three leaflets irregularly disposed of it. "Now leave a blank page in your book. That will help me remember the order in which they come." Next came a flat insect, which, strangely enough, had two legs missing on one side. However, Benda was moving so fast that I had to put it away without comment.
It has been said that the point of resemblance between a cow and a comet, that both have tails, was quite enough for the primitive word-maker: it was certainly enough for the primitive myth-teller. Sometimes the pinnate shape of a leaf, the forking of a branch, the tri-cleft corolla, or even the red colour of a flower, seems to have been sufficient to determine the association of ideas.
Don Pablo next looked out for some palm of a more slender trunk for the rafters and joists. The catinga was the very thing for the rafters. It is tall, nearly forty feet high, but quite slender. It is one of the smooth palms, with pinnate leaves, not unlike those of the "patawa."
With the latter I shall deal at length on another occasion, and therefore I will give here only one very clear and beautiful example. It is afforded by the common red clover. Obviously the clovers, with their three leaflets in each leaf, stand in the midst of the great family of papilionaceous plants, the leaves of which are generally pinnate.
See them again in the white light of a clear noon when the glazed leaves seem to reflect a white veil over the pure verdure; and again when the breeze ripples through the leafy canopy, showing the silvery under-surfaces of the maple leaves, the neat spray of the river birches, the deeply cleft leaves of the scarlet oak and the finely pinnate leaves of the honey locust.
P. chamaebuxus purpureus differs in bearing rich reddish-purple flowers, and is one of the most showy and beautiful of rock plants. They are natives of Europe , and grow best in vegetable mould. An indigenous shrub that grows about a yard high, with pinnate leaves and golden flowers.
Twice or thrice pinnate leaves, toothed like a tenon saw, with conspicuous veins ending in the notches, brand it as the beaver poison, otherwise known as the musquash root and spotted cowbane. From its tuberous roots was prepared the poison which Socrates drank without fear; why should he fear death? Does he not still live among us? Does he not question us, teach us?
The pinnate from pinna, Latin for feather' leaves are composed of from nine to twenty-five leaflets, which are egg-shaped, with a short point, very smooth, light green above and still lighter beneath. These leaves are much liked by cattle, and they are said to be very nutritious to them."
