in spikes, simple or formed of glomerules, with bracts laterally 

 glandular at the base, — 12 genera. 



B. BioTulate Euphorbiacese. 



VI. DiCHAPETALE^. — riowers bermapbrodite or more rarely poly- 

 gamous, perianth double, regular or irregular, petals free or united in a 

 regular or irregular gamopetalous corolla. Stamens fertUe, in number 

 fewer or equal to the petals, hypogynous, perigynous or epigynous. 

 Fruit incompletely dehiscent. Seeds exalbuminous. — 3 genera. 



VII. — Phyllanthe^. — Flowers unisexual, perianth simple or re- 

 gular, petals free or wanting, hypogynous or perigynous, stamens in 

 definite or indefinite numbers inserted in the centre of the flower 

 or round a central body (rudimentary gyneeceum). Fruit dehiscent 

 or indehiscent. Seeds with or without albumen. — 37 genera. 



VIII. Calliteiche^. — Aquatic plants, flowers unisexual or more 

 rarely polygamous perianth (?) simple, 2-merous. Stamens 1-2, 

 Gynseceum 2-carpellary, with ovary cells subdivided into two unio- 

 vulate compartments. Fruits separable into four dry, monospermous 

 parts (demi-cells). Cells albuminous. — 1 genus. 



This family, so divided, has many affinities. They were formerly 

 especially sought amongst the apetalous groups, and there have 

 often been united to the Euphorhiacece all the types formerly united 

 under the name of Urticacece. The Scepaeece and the Antidesmece 

 above all have frequently been connected with the latter, without 

 doubt on account of their amentaceous infiorescence.' Now we know 

 well the slight value of this character, there only remains, it is 

 said, to distinguish the Euphorhiacece from the Urticacece proper, 

 the simple styles of the latter, the absence of the aril in the seeds 

 and the diflerence of properties.^ The Artocarpeoe have often the 

 style divided, which indicates the primitive existence of many 

 carpellary leaves, only one of which is developed in its ovary; 

 and their milky juice gives them properties analogous to the 

 Euphorbiacece ; but the inflorescence has usually a particular configu- 

 ration ; and an Artocarpus may always be recognised at first sight 

 by the arrangement of its stipules in the form of a conical hood, 

 which envelopes all the extreme parts of the branches and leaves
