Flores plerumque unisexuales, simplicissimi; masculi 
e squama pollinifera, feminei ex ovulo apicali, velsaepius 
ex ovulis in margine folii aut prope basim squamae axi 
lateralis eonstantes. Ovula ovario orbata, omnino nuda, 
vel rarius (in Gnetaceis) tunica aperta (perigonium?) 
eincta, frequenter polyembryonata. Tubi pollinis intra 
membranam grani intimam formati; evoluti demum 
cellulas quasdam, corpuscula dictas, in suprema parte 
sacci embryonalis, tangentes. Proembryo intra corpus- 
culi inferiorem partem, e cellulis numero quaternario 
constans, extra corpusculum per centrum endospermii 
fila suspensoria elongata sinuosa emittens embryonem 
extremitate gerentia. Cotyledones 2, nonnunquam par- 
titae. — Arbores vel frutices; vegetatione praesertim ex 
gemmis terminalibus; vasis ligni poris umbiliciformibus 
scatentibus; foliis exstipulatis, plerumque ad membranas 
tenues vel squamas vel limbum angustissimum reductis; 
floribus vulgo in strobilo dispositis, bracteis interdum 
sub singula squama ovuiigera.
