These leaves are small because of the weakness of the young plant and therefore often more or less reduced in structure. But they are usually strictly bipinnate and thereby give testimony as to their descent from species which bear such leaves throughout their life. Other similar cases could be given, but this will suffice.
The most interesting cases are those furnished by the forms which some plants bear only while young, and which evidently connect them with allied species, in which the same features may be seen in the adult state. Some species of the genus Acacia bear bipinnate leaves, while others have no leaves at all, but bear broadened and flattened petioles instead.
During one of the last stages, we discovered a leguminous tree, with the dark fissured bark of the Ironbark, but with large bipinnate leaves, the leaflets oblong, an inch in length; the pods broad and thin, and two or three inches long: this tree is common all over the northern part of the continent, and was found growing abundantly around Victoria, the principal settlement of Port Essington. Mr.
Another pigment, much more valuable, is extracted from a plant of the family of the bignoniae, which M. Bonpland has made known by the name of Bignonia chica. It climbs up and clings to the tallest trees by the aid of tendrils. Its bilabiate flowers are an inch long, of a fine violet colour, and disposed by twos or threes. The bipinnate leaves become reddish in drying.
We passed several dry water-holes shaded by the broad-leaved Terminalia; and saw many Acacias twenty-five and thirty feet in height, with a slender trunk, and an elegant drooping foliage: it very much resembled the Acacia of Expedition Range; but the drooping habit and more distant leaflets of its bipinnate leaves, showed at once their difference. We had travelled five hours and a half, and Mr.
ANGELICA, a genus of plants of the natural order Umbelliferae, represented in Britain by one species, A. sylvestris, a tall perennial herb with large bipinnate leaves and large compound umbels of white or purple flowers. The name Angelica is popularly given to a plant of an allied genus, Archangelica officinalis, the tender shoots of which are used in making certain kinds of aromatic sweetmeats.
It was much better supplied with water, and contained several large reedy lagoons. An elegant Acacia, about thirty or thirty-five feet high, grew on its small flats: it had large drooping glaucous bipinnate leaves, long broad pods, and oval seeds, half black, and half bright red. June 3. We continued our journey down the river, about seven or eight miles.
"A really fine specimen, Mrs. Gallilee, of the Osmunda Regalis. What a world of beauty in this bipinnate frond! One hardly knows where the stalk ends and the leaf begins!" The dog, a bright little terrier, came trotting into the library He saluted the company briskly with his tail, not excepting Mr. Mool. No growl, or approach to a growl, now escaped him.
When in full leafage this is a distinct and beautiful tree, the foliage hanging in well-rounded masses, and presenting a pretty effect by reason of the loose and tufted appearance of the masses of finely-divided leaves. Leaves often 3 feet long, bipinnate, and composed of numerous bluish-green leaflets.
As an ornamental hardy tree this is well worthy the attention of planters, the pinnate and bipinnate foliage being particularly elegant, while the flowers, though individually small, are borne in such quantities of fascicled racemes as to attract notice. The stem and branches are armed with formidable prickles, but there is a form in which the prickles are absent.
