and an inferior ovary. The fourth volume will, it 
hoped, include the Heaths (Ericee) and all the Monopetale with 
superior ovaries, z.c., the COROLLIFLOR# proper. BENTHAM 
and Hooker in the Genera Plantarum have adopted the sub-class 
GAMOPETAL&Z from Endlicher, who had established it in 1836 
to include all orders with a monopetalous corolla, is arrange- 
ment has been followed in the present work from Volume 
onwards, The removal of monopetalous orders from Calyciflore 
does not, however, affect the sequence in which they are dealt with. 
But in order to make the classification consistent throughout, it is 
necessary in the first place to substitute the following new definitions 
is sub-classes 1-3 for those given by Professor Harvey in Vol. 
XX Xl.’ 
3 Sub-class I.—Twanamirtorm. Ord. I.-XLI. (Vol: Ty 
pp. 1-449). Calyx and ashi Jeet eO present. Petals 
separate, inserted, as are or he stamens, on the receptacle 
(i.e., hypogynous). Ovary free. 
“ Sub-class 1,—Cax a a Ord. XLII.-LXX. (Vol. I 
pp. 450-528; Vol. IL., pp. 1-572). Calyx and Corolla 
hat erally) present. Petals separate. Stamens inserted on 
he calyx (perigynous) or on the ovary (epig pe Pied free 
or more or less adnate to the calyx-tube. Balano- 
phoree (Vol. IL., p. 572), and Lexi. Tarenthacea 
(Vol. IL., p. 574) are,transferred to MonocHLAM 
“ Sub-class 111.—GamorrtaLs®. Ord. LUX XIII. "CVL (Vols. 1 3 
IV., and V.. sect. 1, pp. 1-392). Calyx and Corolla both 
ahaicse Petals united in a gamopetalous corolla, Stamens 
inserted upon the corolla. Ovary free or more or less adnate 
to the calyx-tube. 
“In the second place, t he ‘Sequence of Orders’ in Vol. IIL, 
p- ix., must be remodelled as below; the definitions of the orders 
themselves are unaffected. 
“ Sub-class II.—Gamorrtata, Ord, LX XIIL-LXXVIL. 
“ Series _—Inrer®. Ord. LX XIIIL-LXXVII. Ovary inferior.
