BENTHAM AND HOOKEB’s GENEEA PLANTAETTM. 83 
under the head of '* Formae ahnormes which we find immediately fol¬ 
lowing the description of each Order. We copy by way of example 
the abnormal forms of a small Order, Nymphseaceae, of which 
Nelumboneae and Cabombeae are regarded as Tribes. 
“ Caulis mucilagine indutus, in Cabombeis. 
Polia basi cordata v. Integra, nec peltata, in Barclay a , snbmersa 
dissecta in Cabomba. 
Petala et stamina definita in Cabombeis. 
Ovarium omnino inferum in Victoria et Furyale. 
Semina exalbuminosa, in Nelumbone. Testa villosa in Barclay a.” 
The descriptions of the Natural Orders appear to be extremely 
well drawn up. Appended to each is a short notice of the marks 
which distinguish it from nearest allies as well as from other groups 
which present only points of analogy, though these latter are more 
precisely indicated in the ‘ Genera affinia aut exclusa v. dubia a list 
of which follows the ‘ Conspectus Generum ’ of the Order. These 
lists of abnormal and of allied, excluded, or doubtful genera, &c., are 
very valuable indeed, and a great boon to working botanists. It 
would be utterly foreign to our present purpose to examine these in 
detail, and their criticism we are not bold enough to attempt. We 
have only cordially to thank Messrs. Bentham and Hooker for the 
pains which they have bestowed to make them so comprehensive. 
Amongst the more important changes in the circumscription, &c. of 
the Natural Orders, we note Lardizabaleae constitute a tribe of Ber- 
berideae Calycanthaceae are brought between Dilleniaceae and 
Magnoliaceae, notwithstanding the apparently perigynous insertion of 
the stamens. This is shown to be due to an expansion of the torus, 
similar to that presented by Fupomatia and Nymphaea. Pumaria- 
ceae form a tribe of Bapaveraceae ; Pangieae of Bixineae. Pran- 
keniaceae is maintained independently, and immediately precedes 
Caryophylleae, which latter includes Polycarpeae. Elatineae is also 
kept up near to Hypericineae; Bhizoboleae form a tribe of Ternstro- 
miaceae. The changes introduced in the Malval Alliance have been 
already treated of by Mr. Bentham in the Linnean Society’s Journal. 
Erythroxyleae and Ixonantheae are tribes of Lineae. Nitraria 
is referred to Zygophylleae. Geraniaceae includes Oxalideae and 
Balsamineae. Bntaceae is very comprehensive, embracing, besides 
Cusparieae and Diosmeae, &c., Zanthoxyleae and Aurantieae. 
Balanites and Humana go into Simarubeae. Phytocreneae form a 
tribe of Olacineae. Brinos is reduced to Ilex ; Hippocrateae to a 
tribe of Celastrineae. Stackhousieae and Sabiaceae are maintained 
ordinally distinct, while Acerineae and Staphyleae are reduced to 
tribes of Sapindaceae. Sabiaceae, we observe, appear in an en¬ 
tirely new aspect, not limited to the typical genus Sabia , but inclu- 
* A new genus from Chili, received at Kew since the printing of the ‘ Genera 
Plantarum,’ remarkably confirms the propriety of this union. It forms the con¬ 
necting link of the two tribes.
