RECEPTACLE. 3 



to the common part in the aggregate ; thus, besides a common ca- 

 lyx, each floret may have its own proper calyx. 



Linnseus enumerates seven kinds of aggregate 

 flowers. 



1. AGGREGATE FLOWER, (Jios aggregatus) properly so 

 called, which has a common undivided receptacle, the 

 anthers all separate and distinct. 



Observation. Flowers visually blue, purple or white. 



2. COMPOUND FLOWER (flos compositus) has also a 

 common undivided receptacle, but the filaments, which 

 are five, have their anthers united into a tube. Ex. 

 Dandelion, Sunflower, Daisy, &c. 



Observation. These constitute the class Syngenesia, which see. 

 Flowers usually yellow, especiall} in the centre or disk. 



3. AMENTACEOUS (Jlos amentaceus) has a thread- 

 like receptacle, along which are disposed scales, 

 each of which is accompanied with one or more sta- 

 mens or pistils. Ex. Willow and Alder. See AMENT, 

 page 48. 



Observation. 1. The greatest part of the amentaceous flowers arc 

 separated. 



2. The birch, betula ; beech, fagus ; poplar, popidus ; hazel, 

 corylus ; hornbean, carplnus ; pine, pinus ; walnut, juelans ; oak, 

 quercus ; and some other trees, are amentaceous The fertile flow- 

 ers of some of these are not aments, as the walnut, oak, and hazel. 



4. GLUMOSE, (flos glumosus) has a slender, thread- 

 shaped receptacle, along which are disposed a number 

 of florets, all enclosed in a common calyx, termed 

 GLUME, (gluma.) Ex. Grasses. 



5. SpADicEous 9 (Jlos spadiceus) a sheathed flower, 

 in which the receptacle common to many florets is a 

 spadix'y enclosed with a sheath (spatha.') Ex. Common 

 Dragon Wild Turnip, JUnnn.* 



6. UMBELLATE, (jflos umbettatui) in which the flo- 

 rets are borne on footstalks produced from a common 

 receptacle. Ex. Hemlock, Carrot. See UMBEL, p. 42. 



7. CYMOSE, (Jlos cymosus) consists also of florets 

 borne on foot-stalks produced from a common recep- 

 tacle. Ex. Elder, Smnbucus. See CYME, p. 43.
