Class 11

CLASS 11. Distinguished from the last Class, only by baying separate anthers.

56. Dipsacea consist of some of the Lineman Ag. make, urn. 48. See our remark under Jussieu's 26th order. There is ample room for speculation on the affinities and distinctions between these Dipsacea, the Protege, ord. 26th, and the whole of J.ussieu's 10th class last mentioned. Their contemplation involves questions at any time sufficient to excite a botanical war--euch as, what belongs to inflorescence, and what to the flower / what is a calyx, and what the crown of the seed ? what is superior and what inferior insertion what a simple and what a compound flower ? 57. Rubiacee, a vast and important order, compos ed, not only of the Linntean Stellate, .ord. 47, but also of numerous tribes of shrubby plants, very few of which had been referred to the Mdlate, and many of them had not Wien under the notice of Litmus at all. Jussieu shines in the elucidation of this order, and has well indicated certain characters in the habit, especially that of the intrafollaceous sheathing sti pules.

. 58. Capnfolia are nearly equivalent to the 4th, or last, section of Linnaeus's Aggregator, ord. 48, except Viburnum and its allies, With Coma and Hedera ; the former placed, without much reason, in the Lin mean Dumoser ; Corms with the Stellate; and He dera in Hederacea, ord. 46, nearly agreeing with Jussien's 59th next mentioned. Comas and Hedera, being both allowed to be polypetalous, really belong to the next class, as the author could not but perceive. Indeed Jussieu's 11th and .12th classes, however die. tinct in theory, naturally slide into each other.

59. Aralia answer to the Linnaean

Hederacee,ord. 46, Bedera, Val and Cisme excepted, which Linnaeus himself appears to have had some idea of removing from Panes, &c.

60. Umbelhfere of course correspond with the Umbellate, ord. 45, of Linnaeus, one of the most na tural of the whole.

Cease 13.

61. Ranunculacee answer to die Linnaean Wad iiqua, ord. 26. The authors differ in the denomina tion of the parts of the flower, Jussieu's calyx being sometimes the corolla, and his petals the necsaria, of Linnaeus.

62. Papaveracee are, except Hypecouns and Ftk mark, Linnean Moeda', ord. 27, 63. Crualera the Linnsean Si:intro:a, ord. 39, so natural an order, that we can scarcely say to which it ' is next akin.

64. Capparides mostly Linnaean Putaminea, ord. 25, with some very anomalous genera subjoined as related thereto, Reseda, Drosera and Parnastia, not without great and well-founded doubts of the author.

65. Scan&

These are comprehended in twe 66. Accra of the sections of the niblicks, 67. 1Walpighie ord. 23. of Luuueus.

68. Hyperica. Ascyrum and H the only real genera of this order, are, with sates. subjoined to the Linnsean Rotates, ord. 20; cerminly with no very evident reason.

, 69.

Guth:fere constitute a well-marked order, to which Linnaeus has nothing anelogona. Most of the genera that compose it, are either left by him =ar ranged, or considered as of dubious affinity to ape others. Indeed they are geacmlly tropical trees, re specting which he had but slight infermation, 70. Aurantia. Of this likewise Linnaeus seems to . have formed no ideal, since he refers Citrate to his Bicornes, and leaves Limonia undetermined. Ca walla and Pica, subjpinal by with same other genera, to this order, as connecting it with the next, appear to us of very dubious affinity. to the Au rantia nor are they much better annexed by Lin anus to his Colutansferar, ord. 37.

.71.

Melia constitute a good order, comprehended, not very judiciously, under the linnteau Trikikta, ord. 23, above mentioned. • 72. Viten, consisting only of Cirrus and Vatic, we have already mentioned, ord. 59, as included amongst the Hakraceas, ord. 46, of Linnaeus.

. 73.

Gerania make a part of the Liumean Gruissdn, ord. 14, but Trope:ohm, a puzzling genus, which Jussieu labours to prove in many respects related to them, referred by LABIUM; as reasonably perhaps, to his Trihilatn.
