list of genera, might be beneficially dispensed with. In the mean time it is quite impossible, 

 by the characters given, to distinguish Visiania from the Indian Olives; I, therefore, in pub- 

 lishing a figure of one of the species, referred it to Olea^ the terminal, panieled inflorescence 

 forming the only distinguishing mark, and to this so high a generic value is not yet accorded, 

 however useful as a specific or even sectional character. 



The species employed to illustrate the order is 0. dioica, as exhibiting petaled and apeta- 

 lous flowers, but my specimens being defective in ripe fruit, I have in a supplementary plate 

 given analyses of other two species, one with long, the other with short petals, also of a species 

 of Linociera^ to show the difference in the position of the ovules and structure of the seed. 

 The position of the ovules merits much attention in this family, as by their direction we are 

 enabled to determine the place of an unknown species even without fruit. Roxburgh seems 

 to be the only author who has noticed the amphitropal position of the ovules in the description 

 of his Chionanthus dichotoma^ and was the first to assign want of albumen as part of the 

 generic character. Endiicher has introduced it into his character, but states that the ovules 

 are suspended from the apex of the septum, which is not the case in any of those I have 

 examined. In Chondrospermum the ovules are attached a little below the middle, and are. 

 ascending, which led Wallich, when he first described that plant, to suggest that it might more 

 properly belong to Jasminece. De Candolle has acted on that suggestion and placed the genus 

 at the head of that order, as forming the connecting link between the two, and it certainly 

 participates in some of its characters of both, but of the two seems more nearly to approach 

 Oleace(B in the valvate aestivation of its usually 4-lobed corolla and sessile stigmas. But, view 

 it as we may, it is a very anomalous genus and might with nearly equal propriety be referred^ 

 so far as yet known, to either. The fruit, unfortunately, is still unknown^ and until it is found 

 its true place cannot be determined.
