Lepidozamia hopei, commonly known as Hope's cycad or zamia palm, is a species of cycad in the family Zamiaceae, endemic to a small part of the Australian state of Queensland. It grows as an understorey tree in rainforest, and is reputed to be the tallest known species of cycad.
Description
Hope's cycad is a tree reaching up to Template:Cvt high and Template:Cvt trunk diameter. It normally has a single trunk and crown, although forked trunks occur on occasions. The fronds may reach up to Template:Cvt long with as many as 200 leaflets each. The leaflets are dark green, fairly stiff, and up to Template:Cvt wide and Template:Cvt long. The cones are quite large – male cones measure up to Template:Cvt tall and Template:Cvt diameter and female cones are up to Template:Cvt tall and Template:Cvt diameter. The seeds when mature measure about Template:Cvt long by Template:Cvt wide and are sheathed in a bright red sarcotesta.Template:R
It is reputed to be the tallest known species of cycad and it towers over other understorey vegetation, but rarely reaches the forest canopy.Template:RTemplate:R
Taxonomy
This plant was first described in 1865, as Catakidozamia hopei, by Scottish-Australian botanist Walter Hill who published the description in The Gardeners' chronicle and agricultural gazette.Template:R It was later transferred to the genus Lepidozamia by German botanist Eduard August von Regel, who published the new name in 1876.Template:R
Distribution and habitat
Lepidozamia hopei is found in a small part of northeast Queensland, from the area around the Bloomfield River in the north, to the lowlands just south of Tully. It inhabits rainforest and neighbouring forests at altitudes from near sea level to about Template:Cvt. Template:R
Conservation
This species has been assessed to be of least concern by the International Union for Conservation of Nature (IUCN) and as 'Special Least Concern' (SL) by the Queensland Government under its Nature Conservation Act.Template:R The status SL is unique to Queensland, and lies between 'Least Concern' and 'Near Threatened'.Template:R
Ecology
The seeds are eaten by cassowaries and the sarcotesta that covers them are eaten by native rodents.Template:R
