408 NATURAL HISTORY OF PLANTS. 



accepted by De Candolle 1 and Endlicher, 2 but left by them in the 

 neighbourhood of Myrtacea ; while Lindley 3 in 1846 placed it in 

 his alliance Grossales, between Escalloniece and Barringtoniece. It 

 then contained Deutzia, Philadelphus, and Decumaria. Latterly 

 American botanists have added Jamesia* Fendlera? Wipplea, 6 and 

 Carpenteria / and we have since referred 8 to this group, as a link 

 between it and the Escallonicce, the genus Pterostemon, formerly 

 classed with Rosacece-Quillaiea. These eight genera have the 

 following characters in common, linking them with Hydrangea : 

 leaves opposite exstipulate ; 9 stamens diplostemonous, or more 

 numerous in oppositipetalous phalanges. Ovary inferior in half the 

 genera, almost completely superior in the four new American genera 

 enumerated above, where the receptacle is a shallow cupule ; fruit 

 capsular ; seeds albuminous. 



VIII. Escalloniej3. — A series formed of trees and shrubs, with 

 alternate exstipulate simple leaves, often coriaceous, with glandular 

 teeth. Flowers usually isostemonous. Receptacle more or less con- 

 cave. Ovary wholly or partially inferior, with two or more complete 

 or incomplete cells (12 genera). II. Brown 10 made Escalloniece a 

 distinct order, to comprise Anojjterus and several unpublished 

 Australian genera; this order was adopted by Lindley. 11 De Can- 

 dolle, 12 on the contrary, only made Escalloniece a tribe of Saxi- 

 fragacece, comprising, besides Escallonia, the four genera Ilea, 

 Forgesia, Anoplcrus, and Quintinia.' 2 Lindley added Carpodetus of 

 Forster, 14 and Choristylis of Harvey. 15 Bentham and Hooker 16 

 further add Valdivia? inseparable from Escallonia, and Argopkyllum™ 

 which cannot be placed away from Carpodetus; besides Polyosma?
