 shrubs (and trees) with opposite or whorled leaves; stigma usu- 

 ally bifid. Lavendula, Ncpeta, Stachys, Salvia, Thymus, Mentha, 

 Coleiis. (Pf. IV, 3a, 183.) 



Sub-Class DICOTYLEDONEAE-CALYCIFLORAE . " Cup 

 Flowers." Axis of the flower normally expanded into a disk or 

 cup, bearing on its margin the perianth and stamens (or the lat- 

 ter may be attached to the corolla.) 



Super-Order Calyciflorae-Apopetalae. Petals separate. 

 Carpels many to few, separate to united, superior to inferior. 

 This super-order originates near the beginning of the Axiflorae, 

 and indeed the orders Ranales and Rosales are unquestionably 

 closely related. 



Order Rosales. Flowers usually perfect, actinomorphic to 

 zygomorphic (regular to irregular) ; carpels separate or more or 

 less united, sometimes united with the axis-cup ; styles usually 

 distinct. 



Family 192. Rosaceae. Roses. Herbs, shrubs, and trees with 

 mostly alternate leaves ; stamens usually indefinite ; carpels i to 

 many, free (but they may be enclosed in the deep cup) ; ovules 

 usually 2, anatropous. Potentilla, Fragaria, Spiraea, Rosa. (Sp. 

 about 2700.) (Pf. Ill, 3, I.) 



Family 193. Malaceae. Apples. Shrubs and trees with alter- 

 nate leaves ; stamens usually many ; carpels few. More or less 

 united, and adnate to the axis-cup, so as to be " inferior." Sor- 

 bus. Pirns, Mains, Crataegus. (Pf. Ill, 3, i and 18.) 



Family 194. Prunaceae. Plums. Shrubs and trees with alter- 

 nate leaves ; stamens many, on the cup margin ; carpel one, in the 

 bottom of the deep cup, becoming a drupe. Prunus, Amygdalus. 

 (Sp. 150.) (Pf. Ill, 3, I and 50.) 



Family 195. Crossosomataceae. Southwest North American 

 shrubs, with small leaves and a bitter bark ; sepals and petals 5 

 each; stamens 20 or more; carpels 3-5. Crossosoma. (Pf. 

 Nach. 185.)
