Abies ferreana var. longibracteataPinaceae1997
Notes on Gymnosperms I. Taxonomic Treatments of Some Chinese Conifers
作者:Li Nan, Fu Li-kuo
文献:Novon. 7 (3): 261 (1997)
形态描述:A var. ferreana recedit strobilorum bracteis exsertis, non recurvatis, spice attenuatis. The new taxon is readily distinguished from va-riety ferreana by having distinctly exserted, acu-minate bract scales that are lanceolate at the apex and neither reflexed nor recurved. In contrast, va-rietyferreana has usually reflexed or recurved bract scales that are rounded at the apex with an acute cusp.
