COROIXIFLOE^. 56a 



epigynous stamens, yet several exceptions occur, which should 

 be particularly noted by the student. Thus, we find apetalous 

 plants in the Celastracece, Ehamnacece, Anacardiacece, Leguminoscs, 

 Bosacem, Lythracece, Saxifragacece, Cunoniacece, ParonychiacecB, 

 Mesemhryacece, Fassijloracecs, MyrtacecB, Ojiagracecs, HaloragacecB, 

 Combretacecs, HamamelidacecB, and Araliacea. Monopetalous co- 

 rollas occur commonly in StackhousiacecB,Fa^ayac€(S, Cucv.rhitaceoB, 

 and BelvisiacecB, and occasionally in Crassidacea, PortidacacecB, 

 LecythidacecB, and Araliacece. In some Calycifloral Exogens, 

 again, the stamens are wholly, or in part, hj-pogynous or nearly 

 so, as in Anacardiacece, Connaracece, Leguminoscs, Saxifragace<B, 

 CrassulacecB, Francoacece, Paronychiacecs, and Portidacacece. 



Unisexual flowers always occur in Hensloviacece, PapayacecB, 

 Pangiacecs, and CucurbitacecB, and sometimes in Bosacece, Hy- 

 drangeacecB, Passijloracece, Grossidariacece, Haloragacee, Combre- 

 tacecB, CornacecB, HamariielidacecB, and Araliacece. 



Exceptions also not unfrequently occur to the characters upon 

 which the perigynous and epigynous sub- divisions of the Calyci- 

 florse are founded. Thus, in the Perigynae we sometimes find 

 the ovary partially or wholly inferior instead of superior, as in 

 Vochysiacece, TiharanacecB, Anacardiacece, Bosacece, Saxifragacece^ 

 Hydrangcacece, CunoniacecB, Portidacacece, and Mesemhryacece. 

 But the exceptions to the ordinary inferior ovary of the Epigynae 

 are much more rare, only occurring commonly in Myrtacece, 

 Melasto'macecB, and Bruniacece, where the ovary is sometimes 

 partially or wholly superior. 



Sub-class 3. — Corolliflorce. 

 1. Epigynae. 



The Natural Orders placed in this sub-division of the Corol- 

 liflorse were included by De Candolle in the Calyciflorse ; the 

 Corolliflorse being restricted by him to those monopetalous orders 

 in which the corolla was hypogynous, and the ovary consequently 

 superior, and which are placed in our arrangement in the sub- 

 divisions Hypostaminese and Epipetalse. The simplest arrange- 

 ment, however, for the student is, to consider the Monopetalous 

 Corolla as the essential mark of the Corolliflorse, and in accord- 

 ance with this view we place this sub-division here. It should 

 be noticed, however, that some monopetalous orders have been 

 placed by us in the Calyciflorse. (See above.) 



Natural Order 122. Caprifoliachs. — The Honeysuckle 

 Order {figs. 9-ii-9-i6).— Character. — Shrubs, or rarely herbs. 

 Leaves opposite {fig. 259), exstipulate. Calyx superior {fig. 

 944), 4 — 5-cleft, usually bracteated. Corolla monopetalous {fig. 

 945), 4— 5-cleft, tubular or rotate {fig. 945), regular {fig. 945) 

 or irj^egular, rarely polypetalous. Staraens {fig. 945), 4 — 5,
