ORGANOGRAPHY 



BOOK I. 



tain honi-like processes are cornita, or horns; the upper end 

 of these is the beak, or rostrum, and their back, if it is dilated 

 and compressed, is the ala, or appendix ; occasionally there is 

 an additional set of horns proceeding from the base of the 

 orbiculus, and alternate with the horns, these are ligulcB ; the 

 circular space in the middle of the top of the orbiculus is the 

 scutum. Brown names the orbiculus corona staminea, and its 

 divisions ^Z/o/a, or leaflets. 



In some plants, as Cynoglossum, the lamellEe are very 

 small, scale-like, and overarch the orifice of the tube ; such 

 have received the name o^ fornix. 



Link calls every appendage which is referable to the corolla 

 a pai'acorolla ; or, if consisting of several pieces, parapetalum ; 

 and every appendage which is referable to the stamens a 

 parastemon. The filiform rays of the corona of Passiflora the 

 same author calls paraphyses or parastades. 



Moench names such appendages of the corolla as the fila- 

 mentous beard of Menyanthes perapetalum, and Sprengel calls 

 the same thing nectarihjma. 



In Ranunculus there exists at the base of each petal a little 

 shining, sometimes elevated, space which secretes honey. This 

 is the true nectarium or nectarosti(/ma of Sprengel. By some 

 writers it has been considered a kind of reservoir, in which 

 there is much plausibility ; but it seems to me, from analogy, 

 to be a barren stamen, united with the base of the petal, and 

 to be of the same nature as the lamella of other plants.
