ftiid in tlie presence of albumen, it is very near tlie Passifloraeeae ; but in 

 tlie gamopliyllous corolla, it approaches tlie Cucurbitacese. 



207 Caricaceae^*: In tlie stmcture of tlieir ovaries, tlie Caricaceae are 

 closely related to the Passifloraceae ; but in tlie stnTcture of the o^-ules, they 

 are related to the Cuciu-bitacese (Van Tieghem:). 



208 Loasaceae'^ : De Candolle refers this family to the Calyciflorae on 

 ficcount of the rudiments of the stamens,- and places it near the Oenotheracese 

 and Portulacaceae ; at the same time, he gives as the near kin of the Loasa- 

 ceae the Passifloracese and Tumefacege on one side, and the Papaveraceae and 

 Cucm-bitacese on the other. Bentham-Hooker regard the Loasacese as a re- 

 lation of the Begoniaceae, Cucurbitacea3 and Dipsacaceae, while EichIiER finds 

 iu the Loasacege a type midway between the Passifloracese and the Myrti- 

 flor?e. LiNDiiEY, however, aflfirms its relation to the Cactacese. It is also near 

 the Turneraceae. At any rate, it cannot be denied that there exist many 

 points of resemblance between the Loasacece and the .Begoniacese, especially 

 in the stnicture of the seeds. 



209 DatiscaceaB^^ : This family -vvas at one time placed close to the 

 Saxifi-agaceae, but at another, near the Cucurbitacefe. Baillon regards it as 

 a transitional form between the Piperacese and the Urticaceae. Lindley, and 

 Benth.-Hooker put the Datiscaceae near the Begoniaceae, wliile De Candolle 

 briugs the family close to the Loasacese. Its intimate relation to the Bego- 

 niaceae is particularly referred to in the following Hnes. 



210 Begoniaceae^^ : These are closely connected with the Datiscaceae, as 

 can be seen in the inferior ovary, in the manner of the deliiscence of the fniit 

 and iu the shajje and stnicture of the seeds and seedhugs. On the other liand, 

 the intimate relation between the Begoniacese and the Cucurbitacese is incon- 

 testable, as both families agree perfectly in the unisexual flowers, in the iu- 

 ferior ovaries, in the connate stamens, in the cystohth, in the shape and 

 nerv-cs of the leaves, in the placentas, and in the seeds. The Saxifragacege 

 may be regarded as kin of the Begoniace?e, as the two famiHes agree in the
