ROSACEA. 427 



a glabrous shrub from Malaysia, whose alternate simple per- 

 sistent lanceolate leaves possess ill- developed lateral stipules. The 

 flowers are small and numerous, in lax slender axillary or terminal 

 racemes. 



The group of the Rosacea is so very natural that its extent and 

 limits were early foreseen. B. de Jussieu, in his Catalogue of the 

 Grarden of the Trianon,' and Adanson, in his '''Families des Plantes"" 

 may, however, be considered as having clearly marked out, the one a 

 Natural Order {Rosacea), the other a Family of the Roses {Rosa). 

 A. L. DE Jussieu, in defining his order Rosacea,^ greatly enlarged 

 the frame drawn up by his predecessors ; for, besides the genera of 

 Rosacea now-a-days admitted by botanists, he included Tetracera, 

 Tiff area, and Delima, which are DiUe?iiacea ; Suriana, now placed in 

 Rutacea ; Prockia, a genus since attributed to Bixacea or TUiacea ; 

 those Homaliacea that were known in his time, viz., Homalium, 

 Napimoga and Blackwellia, besides Cali/cantJius and Plinia, a Myrtad. 

 It was A. P. DE Candolle^ who definitively excluded most of these 

 genera from Rosacea ; and, with the exception of Cephahtus' 

 Amoreuxid' and Trilepisium^ the genera which he kept in this order 

 are still maintained by most botanists of the day. He also resisted 

 the tendency to follow the example, which R. Brown^ had recently 

 set in considering as so many distinct orders the secondary tribes 

 which A. L. DE Jussieu had made in his single order Rosacea, viz., 

 Pomacea, Rosa, Sanguisorba, Poteniilla, Spirea^ Amygdalea. But 

 Endlicher'" and Lindley'^ followed this example. The former dis- 

 tinguished in his large class Rosifora, the five orders Pomacea, 

 Calycanthea, Rosacea (subdivided into Rosa, Bryadea, Spiraacea, 

 and Neuradea^') Amygdalea and Chrysohalanea ; the latter made the
