Vascular – Native
The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Current conservation status
The threat classification status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Coastal to montane in dry, rocky habitats with only sparse or no vegetation cover. Often found growing with Pellaea calidirupium. More common in the drier eastern parts of the country.
Terrestrial or rupestral fern. Fronds up to 350 × 35 mm; stipe and rachis dark brown or red-brown, glabrous or with sparse to moderately dense hairs (to 10 cells, often twisted and glandular), densest at stipe-rachis-rachilla junction, with some scales. Lamina linear-lanceolate or ovate, 3-pinnate at base, 2-pinnate for most of length; larger pinnae triangular-ovate; pinnules lanceolate ovate or elliptic; margins deeply incised, inrolled; adaxially glabrous, abaxially glabrous rarely with a few, sparse hairs. Spores spherical, verrucose, with varying amounts of globular, branched or reticulate deposits; either black, ridged, 49-73 microns diameter and 16 per sporangium, or brown, trilete, 36-52 microns diameter, and 32 per sporangium.
Distinguished from Cheilanthes distans with which it often grows by the the glabrous (or nearly glabrous) primary pinnae

Minute spores are wind dispersed (Thorsen et al., 2009).
Easily grown in a dry sunny site. An excellent pot plant. In ideal conditions it soon self establishes.
cheilanthes: From the Greek kheilos ‘lip’ and anthos ‘flower’, referring to the indusium
