CLASSIFICATION. 



Cucurbitaeeaa (the correct position of which is doubtful) and in many 

 Mimotaceaa (where it is very small). 



Where there is only one perianth whorl, this may be corolloid 

 (petaloid) and gamophyllous, e.g., Mirabilis, Borgainvillea, Loranthus, etc. 



Carpels only two in Cruciferaa, Umbelliferae, Moracese, Ulmacese, 

 Polygalaceae, and in certain genera or species of Ampelidaceae, Euphov- 

 biaceas, Capparidaceae, Bursevaceae, Amarantaceae, Onagraceaa, Myrtacese, 

 Lythraceaj, Tiliaceaa and a few others in which the carpels may be 2-3 

 in the same species. 



Series A (includes Thalamiflorse, Disciuorse, some ApetalcB 

 and a few others of the Genera Plantarum) (p. 57). 



Perianth usually present 2- or more-seriate, of both calyx 

 and corolla (heterochlamydeous) or acyclic with the sepals 

 passing into petals. Sep., pet., and staniens all hypogynous. 

 Orders I to VIII 



Exceptions : — 



Perianth haplochlamydeous, or homo'-hlamydeous and sepaliid in 

 Lauraceae, many Euphorbiaceaj, eome Menispermaceas ; homochlamydeous 

 and petaloid in Moringa and a few others ; wanting in a few Euphor- 

 biacea? 



Petals are absent in some Eanunculaceae, some Lauraceas, some 

 Sterculiaceae, many Euphorbiacaae, some Samydaceaa and Bixaceae. 



The flower is somewhat perigynons in some Capparidacea?, Lanraceaa, 

 Rhamnaceae and other Celastrales, some Samydaceaa and PassifloracaaB. 

 It is epigynous in some Rhamnaceae and in Cucurbit iceae. 



Series B (includes most Calyciflorse and a few Apetalas 

 of the Genera Plantarum). Perianth present 2 -seriate 

 heterochlamydeous and perigynons or epigynous (vide also 

 exceptions under A). Orders IX to XV. (p. 71). 



Exceptions : — 



Periiinth homo::hlamydeons and sepaloid in Viscnm, haplochlamydeous 

 in Santalaceae and perh ips in Loranthus. 



Sepals very small or obsolete in some UmbelUes, Clacalea and Sant*- 

 lales (?) 



Petals in some Caesalpiniaceaa, Combretaceae, Lythraceaa, and 

 perhaps in Loranthacae. 



Fls. hypngynous in some Olacales, and nearly so in some Leguninosa: 

 and Rosacea?. 



Series C (includes the remaining Mor.ochlamydeaa and 

 Achlamydero of the Genera Plantarum.
