Etymology and names

The specific epithet rospigliosii honors C. J. Rospigliosi of the Museum of Natural History in Lima, Peru. [2]

The species has multiple common names in the Spanish language. These include pino hayuelo, pino laso, pino de montana, pino romeron and romerillo macho. [2]

Retrophyllum rospigliosii is an evergreen tree growing up to 45 meters in height and 1,8 meters in trunk diameter. [2] The trunk is usually erect and straight. The crown typically becomes rounded or oval in shape as the tree matures. [2] [3] Branches are generally ascending or spreading, but become pendulous on shaded parts of the crown. [2] The bark is initially brown and weathers dark gray, exfoliating in scale-like flakes. [2] [3]

The leaves are generally flattened with a decurrent base and a spreading blade, but leading shoots may also have appressed scale-like leaves. [2] The leaves are inserted spirally but are twisted on lateral branchlets to appear pectinate and nearly opposite. [2] The pectinate leaves are twisted at their petioles in opposite directions on each side of the shoot causing the adaxial sides of the leaves face up on one side of the shoot and down on the other side. The leaf blades are most commonly 10-18 millimeters long and 3-5 millimeters wide. [2] They are ovate-lanceolate or ovate-elliptic in shape with visible midribs and entire margins. [2] [3] Stomata can be found on both surfaces of the leaf. [2]

The species is dioecious. The male pollen cones are 5-7 millimeters long with spirally arranged triangular sporophylls. The female seed cones each have a single subterminal fertile cone scale with a single ovule developing into a seed. The seed is covered by a fleshy epimatium. The initially green or glaucous epimatium becomes red at maturity and varies from subglobose to ovoid-pyriform in shape with a length of 18-25 millimeters. [2]

Distribution

Retrophyllum rospigliosii is native to northwestern South America. It occurs naturally in Bolivia, [4] Colombia, Ecuador, Peru and Venezuela. [2] [3]

Retrophyllum rospigliosii is a large rainforest tree. It occurs in montane tropical rainforests and cloud forests at altitudes between 1500 and 3750 meters above the sea level. [2] Most commonly the species grows scattered among other trees, most of which are angiosperms, but on certain sites it may also form pure stands. [5]

Cupressaceae The cypress family of conifers

Cupressaceae is a conifer family, the cypress family, with worldwide distribution. The family includes 27–30 genera, which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to 116 m (381 ft) tall. The bark of mature trees is commonly orange- to red- brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species.

<i>Podocarpus</i> Genus of conifers in the family Podocarpaceae

Podocarpus is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς + καρπός. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m tall, known to reach 40 m (130 ft) at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their droppings. About 97 to 107 species are placed in the genus depending on the circumscription of the species.

<i>Nageia</i> Genus of conifers in the family Podocarpaceae

Nageia is a genus of conifers belonging to the podocarp family Podocarpaceae. Nageia includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species. Some authors consider Nageia formosensis to be a separate species from Nageia nagi, thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as Nageia were moved to the new genus Retrophyllum, while Nageia falcata and Nageia mannii were moved to the new genus Afrocarpus.

<i>Afrocarpus</i> Genus of conifers

Afrocarpus is a genus of conifers of the family Podocarpaceae. Two to six species are recognized. They are evergreen trees native to Africa. Afrocarpus was designated a genus in 1989, when several species formerly classified in Podocarpus and Nageia were reclassified.

<i>Cunninghamia</i> Genus of conifers

Cunninghamia is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, northern Vietnam and Laos, and perhaps also Cambodia. They may reach 50 m (160 ft) in height. In vernacular use, it is most often known as Cunninghamia, but is also sometimes called "China-fir". The genus name Cunninghamia honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham.

It is a warm-loving and moisture-loving tree of the tropical mountain coniferous and mixed cloud forests of these countries. The Guatemalan fir is an almost completely non-frost-resistant tree. Due to logging and loss of habitat, the tree is considered threatened and is protected in CITES Appendix I.
