antei'ior aide. The ovule has obviously the appearance of being 

 suspended from a funiculus arising in the base of the ovary and 

 adherent to its dorsum. (PI. XIV. fig. 5.) 



PiPERACtJE. In fully developed ovaries of Piperomia magno- 

 licefolia the stigma is alw'ays grooved on its anterior surface, but 

 is rounded posteriorly ; this furrow is also prolonged down to 

 the ovary terminating in a small depression on its summit. 

 (PI. XIV. figs. 3 & 4.) 



The ovary also nearly resembles that of Houttuynia cordata 

 when reduced to a single carpel, which leaves no reason to doubt 

 but that in Piperacese the carpel is posterior. 



Saururaceje. In almost all the spikes oi Houttuynia cordata 

 there are in the upper part dicarpous ovaries, the carpels of 

 which are for the most part anterior and posterior, but occa- 

 sionally right and left ; in sixteen instances (these being all that 

 were observed of ovaries reduced to a single carpel) it was always 

 directly posterior, no trace of a second being present. 



Ranunculace^. In Actcea the greater part are lateral, 

 otherwise indifferently anterior or posterior. 



DiLLENiACEiE. Variable, or more frequently posterior. 



MAGNOLiACEiE. In Tasmannia variable from anterior to pos- 

 terior. 



Menispermace-e. The ovary of Menispermum laurifolium 

 consists of three carpels, one anterior and two obUquely poste- 

 rior, and when reduced to a single carpel its position varies from 

 anterior to obliquely posterior. 



ANACARDiACEiE. In three genera variable, and in Malosma 

 more frequently posterior than anterior, Spondias, which has 

 been regarded as the type of a distinct family, agrees with Ana- 

 cardiacese in having the raphe averse. 



LauracejE, The ovaiy of Sassafras officinale closely resem- 

 bles that oiPrunus and other Amygdalese, the stigma being capi- 

 tate, and the style furrowed on one side and rounded on the 

 other. In S. officinale there is also at the base of the style a 

 small depression in which the furrow in the style terminates; 

 the capitate stigma is also somewhat notched by the furrow ex- 

 tending into its margin, and the ovule is attached to the same 

 side of the ovary at or below the depression at the base of the 

 style (PI. XIV. figs. 6, 7 & 8). The carpel is variable in its posi- 

 tion, being frequently posterior, but in Laurus nobilis it is for the 

 most part lateral. 



Notwithstanding this near approach in structure to Amyg- 

 dalese, the carpels in a dicarpous ovary of S. officinale appeared 

 to be united by their edges forming a one-celled ovary, the styles 

 being also partially united. In Tetranthera also the ovary con- 

 sists of a single carpel.
