Phylum Classe Famiglia Sottoclasse Coniferophyta Pinopsida Pinidae - Conifere Cupressus Alberi, raramente arbusti, diffusi nella zona temperato-calda dellemisfero settentrionale. Hanno rami sparsi o ascendenti. In Italia presente Cupressus sempervirens L. dal caratteristico portamento colonnare. Cupressaceae Phylum

Classe Famiglia Sottoclasse Coniferophyta Pinopsida Pinidae - Conifere Cupressus Cupressaceae Le foglie, verde cupo, sono persistenti, squamiformi, opposte ed applicate con ghiandole resinifere sul rametto, che risulta completamente ricoperto. I cipressi sono monoici: i conetti maschili sono cilindrici, terminali, costituiti da numerosi microsporofilli;

i macrosporofilli portano 6-20 ovuli. Phylum Classe Famiglia Sottoclasse Coniferophyta Pinopsida Pinidae - Conifere Cupressaceae Cupressus Gli strobili (galbule), solitari o riuniti in piccoli gruppi, maturano in 2 anni; sono subglobosi, costituiti da 6-12 squame legnose, peltate, con uno scudo pentagonale che si solleva in un leggero mucrone; le squame sono strettamente imbricate lungo i margini durante la crescita, ma separate a maturit per

favorire la disseminazione. I semi sono piccoli, angolosi e compressi, con ali laterali strette. Phylum Classe Famiglia Sottoclasse Coniferophyta Pinopsida Pinidae - Conifere Cupressaceae Juniperus Comprende circa 60 specie per lo pi arbustive, talvolta prostrate e non superanti i 15 cm di altezza. Le foglie sono persistenti, nelle piante giovani sono sempre aghiformi, nelle piante adulte possono

essere aghiformi (opposte o pi spesso in verticilli di 3) oppure squamiformi (sempre opposte). Phylum Classe Famiglia Sottoclasse Coniferophyta Pinopsida Pinidae - Conifere Cupressaceae Juniperus Specie generalmente dioiche: i conetti maschili sono terminali, allungati e formati da numerosi sporofilli; le infiorescenze femminili sono globose, formate da 3-8 squame che portano 1-2 ovuli ciascuna.
