Fl., or P, K, C, A, may be hypo-, peri- or epi-gynous; the G 

 sttperior or inferior. Perig. fls. may be shallowly or deeply perig. ; 

 in the latter case the tube is described as to length, texture, &c. 

 There may be a disc in the fl. Sometimes outgrowths (effigurations) 

 of the recep r . are seen, e.g. in Passiflora, Capparidaceae, Orchida- 

 ceae. &c. Sometimes the recept. elongates between the whorls of 

 floral members, e.g. in Lychnis between K and C, in Passiflora and 

 in many Capparidaceae between C and A, in Capparis between A 

 and G.. If the elongated portion bears the sta. it is termed an andro- 

 phore, if only the cpls. , a gynophore. Other receptacular outgrowths 

 are seen in epig. flowers, f.g. the wings on the inf. ovary of Begonia, 

 the thorns (which sometimes bear fls.) on that of Tetragonia, the 

 nectariferous disc of Umbel liferae, &c. , and so on. 

 Rectipetality, tendency to grow in a straight line.
