THE ESSENTIAL ORGANS.

and Primrose orders (133). This anomaly is explained 

 in two ways first, by the obliteration of the early- 

 formed partitions, as is actually seen to occur in the 

 Pinks ; secondly, by supposing the placenta to be, at 

 least in some cases, an axial rather than a marginal 

 growth that is, to grow from the point of the axis 

 rather than from the margin of the carpellary leaf, for 

 in Primrose no partitions ever appear. 



136. A few peculiar forms of the style and stigma are worthy of note in 

 our narrow limits, as the lateral style of Strawberry; the basilar style of the 

 Labiatse and Borrageworts ; the branching style of Phyllanthus, one of the 

 Euphorbiacese ; also the globular stigma of Mirabilis; the linear stigma of 

 Mediola; the feathery stigma of Grasses; the filiform stigma of Indian corn; 

 the lateral stigma of Aster; the petaloid stigmas of Iris; the capitate and 

 perforated stigma of Violet (141-149). 



Pistils. 141, Symphytum, basilar style, ovary 4-parted. 142, 9 Flower of Phyllanthus (Euphorbiaceae), 

 branching styles. 143, Mirabilis Jalapa, globular stigma. 144, Flower of Luzula, stigmas linear. 145, 

 Feathery stigmas of a Grass. 146, Stigmas of Aster. 147, Rumex. 148, Poppy. 149, Filiform stigma of 

 Zea Mays (Corn). 



137. In the Pine, Cedar, and the Coniferae generally, 

 both the style and stigma are wanting; and the ovary 

 is represented only by a flat, open, carpellary scale, 

 bearing the naked ovules at its base.
