of scales or hairs on the staminal filaments.^ The Rutacca' of the 

 series Znniho.njlcic^ with the carpels united in a plurilocnlar ovary, 

 and which have been called Toddalica\ ditfer from Burscrac in having 

 leaves without giandularpunctuation, a diplostemonous audroceum, and 

 an exalbuminous embryo. The species of Amf/ris, which, we know, are 

 Jilt facecv, were formerlj^ connected with Burscrece^ again proving very 

 close affinities. Slightly more removed from the Burserecc are the 

 Eiq)horhiacea\ having however, like them, unisexual flowers, pro- 

 vided with a corolla, a diplostemonous audroceum and ovary cells 

 whose two ovules are descendeat with the micropyle exterior and 

 superior. But these Eiiphorhiaccic arc distinguished in such a case, 

 either by the absence of a balsamic juice, or by non-compound leaves, 

 the presence of an obturator above the micropyle, or the existence of 

 albumen.- By the Spondiccc and Anacardiece^ this family so closely 

 approaches the Saju'iidttcecc, that it becomes difficult to separate them 

 distinctly when the flower of the latter is not irregular, and the disk 

 exterior to the audroceum. But the ovule of the Anacardiccr, with 

 its known peculiarities, is characteristic of this group, particularly 

 when it is sujjported by the ascendent funicle, of which we have seen 

 so many examples in the description of t3'pes. The Supindacccc often 

 have an aril, a curled embryo, and usually from two to five cells in the 

 ovary ; which does not exist in the Anacurdieos^ and is observed on 

 the contrary in certain Spondlccc. But in these the ovule is always 

 descendeut, the disk interior to the androceiim, and the flowers 

 regular. When their carpels are independent, at least mostly, as 

 in Bmhanania and SjwudkiSj they thus become very analogous 

 to Habia and the Connaraceoij \)wi the former has petals and sta- 

 mens superposed to the sepals andbiqvulate ovaries, the latter ortlio- 

 tropous and ascendent ovules, and carpels dry and generally dehiscent. 

 There reinaiu the numerous atfinities of the Muppii'w and Plujfocrencw 

 iu the first place with the Olacinece, amongst which some still range 

 them, and which are, we think, more apparent than real, for they are 

 always separated very distinctly^ by not having the stamens opposi- 

 petalous by the placenta being parietal, biovulate, the ovary unilocular 



' The diplostemonous androccum has also ^ These four characters are, it is true, ran^ly
