CLASSIFICATION. 



FIs. small greenish or white, regular 4-5-nierous with never 

 vwrv than 1 whorl of isomerous free stamens (or monadel- 

 phous in some Ampelidace©). Perianth nsnally hypogynous,, 

 sometimes perigynous, or even epigynous (some Rhamnaceae). 

 Disc well developed hypogynous or lining the hypanthium and 

 usually bearing the stamens, sometimes enclosing the ovary. 

 Ovary nsnally 2-5-celLed with 1-2 erect or ascending ovules in 

 each .cell. Style short or 0. 



Exceptions ;— 



Petals in a few Rhamnaceaa, and caducous or in some Vitis. Ovary 

 sometimes 6-celled in Leea, of numerous cells in the aberrant genus 

 Siphonodon (Celaatraceae). 



I . Stamens alternate with the petals. 



36. The Spindle Tree Family. 



Trees or shrnbs, somtimes scandent. L. alt. or opp. 

 Sep. 4-5 small nsnally connate. Petals usually exceeding the 

 iepals sessile inserted below or at the margin of the large 

 prominent disc. Filaments short alternate with the petals. 

 Ovary sessile free or enclosed by the disc. 2-5-celled (or cells 

 many in Siphonodon). Ovules usually 2. Seeds nsnally 

 ariliate. 36. Celastraceae (p. 265). 



II. Stamens opposite to the petals. 



37. The Buckthorn or Jujube Family.. 



Trees or shrnbs, sometimes scandent, leaves simple alt* 

 most frequently with 3-5 basal nerves. Sep. and pet. nsnally 

 5 and perigynons or epigynons. Sep, valvate in bnd and 

 nsnally with a prominent mid-rib within. Petals usually 

 smaller than the sepals, sometimes concealing the stamens 

 which stand opp. to them. Disc thin and lining the bypan- 

 thinm or filling it. Ovary free or united with the hypan- 

 thinm, 3-2-(rarely 4) -celled with 1 basal ovule in each cell. 

 Fr. 1-celled and l*seeded (samaroid in Ventilago) or with
