7nieropyh bent round to them, then the ovule is termed cam-

 A flower wlien composed of 5 petals, of which the upper is next 



the axis, and incloses in bud the other 4, whereof the lateral 



pair, or alx, inclose the lower, which are often adherent by 



their lower margins. 

 The calyx-limb, when reduced to a tuft of bristles or silUy hairs, 



as in the Dundelion. 

 A compound raceme with branched secondary axes. 

 The cellular tissue of plants. 



The supports of the flowers. 



See Leaf. 



The single or double whorl surrounding the andracium and putil. 



The ripe ovary. 



The stamens and corolla arc so when they are inserted on the calyx 



above the base of the pistil. 

 A diclilamydeous flower wlieii lioth whorls are coloured. 

 A dihited petiole, which may replace the true blade. 

 Tlie leaves or segments which go to form the corolla. 

 Tlic stalk of a leaf. 

 The dilated portion of fungus, bearing beneath it the organs of 



fructification in the form of gills, tubes, or processes. 

 Tlie ovuligerous wliorl within or above the andrcccium. 

 The fibro-vascular attachment between the ovule and carpel. 

 The dusty or granular parenchyma contained in the antlier. Tlic 



pollen-grains arc tlie receptacles of the Focilla, wliich is the 



fertilizing agent. 

 A flower with more stamens than ten. Mon, di, tri, tetr, pent, 



hex, Oct, enne, dec(androus), when the stamens arc 1, 2, o, 



4, 5, 6, 7, 8, 9, 10, respectively. 

 A plant which has hermaphrodite flowers scattered among male or 



female ones. 

 Sec Isogynous. 



A calyx whose sepals are wholly separate. 

 Tlie first stage of cellular development of the spore, on the lower

 The stone or bony endocarp of a succulent fruit, as a peach. 

 Small conccptacles in Lichens, of obscure origin and function, 



perhaps supphmientary to reproduction. 

 An inflorescence of wliich the nearly equal secondary axes rise 



along the primary axis. 

 The petiole or stalk ; also the axis bearing the inflorescence of 



grasses. 

 Leaves are so called, which spring from the root, and not, as is 



usually the case, the stem of a plant. 

 In Phanerogams the swollen extremity of a branch, wherein the 



wliorls of a flower are grouped. In the strawberry it forms 



the (so-called) fruit. In Cri/ptot/ams thp, pileus of a mushroom, 



or like fungus, being the dihited portion, on the under surface 



of whicli tlie reproductive organs are developed. 

 Wlien the parts of a whorl are e(iual and similar. 

 Viscous bodies connected with the stamens of Asclepias, which 



secrete a viscid fluid wliich cements together the polleii- 



masscs of two adjacent anthers. 

 The root stock or subterranean prolongation of tlic stem.
