Common Name: CLIFF FERN FAMILY Habit: Trees; rhizome modified as a trunk, generally short-creeping, ascending, or erect; scales especially on trunk tip, stipe bases, small to generally large, generally uniformly tan to brown, among hairs or not. Leaf: generally tufted or short-spaced, 1--1.5[6] m, generally +- alike; stipe firm, not easily crushed, base darker or not; blade [1]2[3]-pinnate [(simple)], +- glabrous or with hairs, hair-like scales, or gland-tipped hairs on axes, veins generally free (netted); axes generally grooved adaxially. Sporangia: sori +- spheric; indusia 0 [saucer- or cup-like to spheric]; spores variously ornamented, scar 3-rayed. Chromosomes: x=69. Genera In Family: 5--6 genera, +- 600 species: worldwide, generally tropics. Note: Some recognize only 1 genus in family. eFlora Treatment Author: Thomas J. Rosatti Scientific Editor: Alan R. Smith.
Common Name: AUSTRALIAN TREE FERN Habit: Trunk generally 1, often thickened by fibrous mass of adventitious roots basally, generally with distinct, +- round or oblong leaf scars. Leaf: generally 2-pinnate, stipe scales of various sizes, not intergrading with hairs or black spines, cells of +- 1 size, orientation (not clearly smaller, of different orientation on margin). Sporangia: sori in 1 row on each side of pinnule lobe midvein. Etymology: (Greek: sphere, fern, for sori) eFlora Treatment Author: Thomas J. Rosatti Reference: Clark & Summers 2013 Madroño: in press
Sphaeropteris cooperi (Hook. ex. F. Muell.) R.M. Tryon
NATURALIZED Habit: Trunk < 1 [15] m, 10--15 cm diam. Leaf: 1--1.5[6] m; stipe <= 50 cm, basal scales <= 50 mm, +- 0.1--5 mm wide, +- white or tan, translucent, among much shorter, bristle-like, dark hairs, margins with bristle-like teeth; blade <= 3.5 m, narrow-elliptic or lanceolate; pinnae <= 65 cm; pinnules <= 12 cm, <= 2.5 cm wide, pinnately lobed +- to midribs (i.e. making frond nearly 3-pinnate), lobes crenate-serrate. Ecology: Coastal, open, rocky cliff faces, in granitic or sedimentary sandstone soils in fog belt; Elevation: < 220 m. Bioregional Distribution: s ChI (Santa Catalina Island); Distribution Outside California: Oregon, Hawaii, western Australia; native to eastern Australia. Note: 20+ pls, 4+ years old, in California population; can survive wide range of conditions, especially with adequate water, so spread is expected. Commonly sold in nurseries in coastal California, southern Oregon. Synonyms: Cyathea cooperi (Hook. ex F. Muell.) Domin Jepson eFlora Author: Thomas J.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
