Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Greek. Etymons: French gamo-; Greek γαμο-.

Etymology: Partly (i) < French gamo- (early 19th cent.); partly (ii) < scientific Latin gamo- (early 19th cent.); and partly (iii) < their etymon Hellenistic Greek γαμο-, combining form (in e.g. γαμοστολικός determining marriage) of ancient Greek γάμος marriage (see -gam comb. form); compare -o- connective.Earliest in the early 19th cent. in sense 1 in formations after scientific Latin or French models. Subsequently in a small number of formations within English in senses 1 and 2 in the 19th cent.

1. Botany. Forming adjectives designating organs in which the parts specified by the second element are fused together, and plants having such organs.

† gamogastrous adj. [after French gamogastre ( A. P. de Candolle Organographie végétale (1827) I. 481)] Obsolete rare (of a pistil) having fused ovaries (with separate stigmas and styles); (also, of a plant) having such a pistil.

ΚΠ

1840 B. Kingdon tr. A. P. de Candolle Veg. Organogr. II. 73 It is usual in this case to say..that the plant is monogynous and polystylous, or with one ovary and several styles; whilst, perhaps, it would be better to say that it is Gamogastrous, or has its ovaries united.

1876 J. H. Balfour in Encycl. Brit. IV. 142/1 The union..may take place by the ovaries alone, while the styles and stigmata remain free, the pistil being then gamogastrous.

1906 J. E. Taylor Flowers (ed. 4) x. 205 The reason why gametopetalous flowers appear later in geological time than polypetalous is because they were transformed from the latter condition.

2005 Amer. Jrnl. Bot. 92 1192/2 The last gamopetalous genus, the Australian Muellerolimon is related to Goniolimon.

ΚΠ

1821 S. F. Gray Nat. Arrangem. Brit. Plants I. 125 It is very rare that a calyx which is not gamosepalous is persistent.

1866 Rep. Proc. Internat. Hort. Exhib. 128 This coloration of the calyx under natural circumstances is more common among polysepalous plants than it is in gamosepalous plants.

1914 F. E. Fritsch & E. J. Salisbury Introd. Study Plants xviii. 236 When the individual lobes of a gamosepalous calyx are of the same size it is said to be regular.
