DECANDRIA. ' 327 



Class 10. Decamb'ia. Stamens 10. Orders 5. 



1. Monogynia. A numerous and fine assemblage, be- 

 ginning with a tribe of flowers more or less correctly 

 papilionaceous and leguminous, which differ very 

 materially from the rest of that natural order in having 

 ten stout, firm, separate stamens. See Cassia, Curt. 

 Mag. t. 107, 62,^, and Sophora, t. 167; also Exot. 

 Bot. t. 25 — 27, 2ind Annals of Botany , v. 1. 501. 



The Rata, Rue, and its allies, now become very 

 numerous, follow. See Tracts on J\'at. Hist. 287. 

 Bictamnus, vulgarly called Fraxinella, is one of them. 

 Diornsa Muscipula, see/?. 146, stands in this artificial 

 order, as do the beautiful Kalmia, Rhododendron, An- 

 dromeda, Arbutus and Pyrola, Engl. Bot. t. 213, &c. 

 (131) 



2. Digynia. Saxifraga, remarkable for having the 

 german inferior, half inferior, and superior, in differ- 

 ent species, a very rare example. See Engl. Bot. t. 

 167, 440, 663, 1009, 500, 501. Dianthus, the Pink 

 or Carnation tribe, and some of its very distinct nat- 

 ural order, Caryophyllecs, conclude the Decandria, 

 Digynia. (132) 



3. Trigynia. The Caryophyllea are here continued, as 

 Cucubalus, t. 1527, Sdene, t. 465, 1398, Arenaria, t. 

 189, 512, very prolific and intricate gerjera in the Le- 



(131) [The last genera, with Erica and Vaccinlum, from 

 the 8th class, and some others, constitute the natural order Bi- 

 cornes, so called, because their anthers are furnished with two 

 long straight points or horns.] 



(132) [The Carijofihyllece have five petals inserted with claws. 

 Cucudahis, Jrenaria, Stellaria, Sec. aie native genera of this order."]
