iu spikes, simple or formed of glomerules, with bracts laterally- 

 glandular at the base. — 12 genera. 



B. Biovulafe Euphorbiacefe. 



VI. DiCHAPETALE^. — ^FlowBrs hermaj)hrodite or more rarely poly- 

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

 regular or ii-regular gamopetalous corolla. Stamens fertile, in number 

 fewer or equal. to the petals, hypogyuous, perigynous or ei>igynous. 

 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 gynseceum). Fruit dehiscent 

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



VIII. Callitric'HE^. — Aquatic plants, flowers unisexual or moi-e 

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

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

 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 apetaloiis grouj^s, and there have 

 often been united to the Eiiphorhiacece all the types formerly united 

 under the name of Urticacece. The Scepacece and the Jntidesmece 

 above all have frequently been connected with the latter, without 

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

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

 said, to distinguish the Eiiphorhiacece from the Urticacece proper, 

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

 and the dift'erence of properties." The Artocarpew have often the 

 style divided, which indicates the primitive existence of many 

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

 and their milky juice gives them properties analogous to the 

 Euphorbiaccoe ; but the inflorescence has usually a particular configu- 

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

 by the an-angement of its stipules in the form of a conical hood, 

 which envelopes all the extreme parts of the branches and leaves
