short and broad. On the top of the ovary, mark the yellow 
epigynous 2-lobed disc or stylopod,* from the division of 
whose lobes the 2 curved styles are produced. Make trans- 
verse and longitudinal sections of the ovary: you will find 
it is 2-celled, and that each cell contains a single pendulous 
ovule. If it is late enough in the season you will find the 
fruit ripe, or nearly so, at the same time as 
the later flowers. The cells of the ovary have 
now become considerably enlarged and slightly 
curved outwards from one another, and they

exhibit 5 slightly-projecting longitudinal ridges. When quite 
mature they finally separate, but remain attached to one 
another by two very slender stalks, which are united below 
and form the carpophore.| Cut a carpel transversely, and 
notice that between each of the ridges lies a flattened channel 
or tube: these tubes are the oil-canals, or vittee,+ and it is 
probably to the volatile oii contained in them that the powerful 
aromatic smell of the seed is due. In longitudinal section you 
will see that the seed adheres very closely to the pericarp, and 
that it is full of a dense endosperm, towards the upper end of 
which lies the small embryo. |

(4.) There are many other plants which may be examined instead of 
or along with Parsley—e.g., Celery, either the cultivated plent (Apiam 
graveolens) or, still better, the two new Zealand species (A. australe and 
A, fiiiforme), which are both common along many parts cf our sea-coasts ; 
Carrot (Daucus carota), or the New Zealand species (D. brachiatus), in 
which the carpels have nine ridges covered with short hairs or spines ; 
Fennel (Feniculum vulgare), which is avery common weed in many parts, 
particularly of the North Island; and Parsnip (Pastinaca sativa).
