Creeping


These ferns send up fronds as they creep along.

Bracken   Rahurahu

Pteridium esculentum

 
A waist high fern growing in the scrub like conditions where recolonisation in occurring. Maori used the rhizomes as a food (Starch)  
 

Climbing shield fern   

Rumohra adiantiformis

 
Not common, visible veins and shiny surface.  
 

Common maidenhair fern   Puhinui / Tawatawa

Adiantum cunninghamii

 
This fern has fronds which appear a bluey green colour. The black shiny stipe (midrib) is longish and holds the frond up above ground growing species. It is hairy at the base and this can be used to distinguish it from the smaller maiden hair (Adiantum diaphanum) but the most obvious difference is that the A. diaphanum has only three branches at the end of the stipe.  
 

Deparia?   

Deparia petersenii?

 
This is a soft fern found along with the bracks near the tracks. It has green stipes not brown. Deparia is believed to be an introduced species.  
 

Filmy fern   Matua mauku

Hymenophyllum

 
Found covering a vertical bank well out of the reach of stock  
 

Fork fern   

Tmesipteris lanceolata fern

 
This tiny forked fern is not a true fern, usually found on the ponga ferns in the more northern part of the reserve.  
 

Fragrant fern   Mokimoki

Microsorum scandens

 
Frequently found in the Mangemangeroa Reserve covering decaying stumps. Fragrant fern fronds have dark veins. The lance fern does not. Used by the Maori as a scent for hair and as a body oil scent. It smells like almond icing.  
 

Hanging Spleenwort   Makawe

Asplenium flaccidum

 
A pretty fern, hanging in tufts from tree trunks.  
 

Hound's tongue fern   Kowaowao (Paraharaha)

Phymatosorus pustulatum (Crowe)

 
The Hound's Tongue fern has prominent veins on a dark shiny fronds. Spores can be seen as quite definite circular indentations.  
 

Jointed fern   

Arthropteris tenulla

 
This fern looks more like a leaf than a frond.  
 

Lastreopsis sp.   

Lastreopsis microsora

 
Creeping fern (short rhizome) Soft pretty fern, growing abundantly where previously heavily browsed by stock. Has a brownish smooth stipe (midrib) and fronds are a bluey-green colour. Sori are like balls of "fluff" arranged away from the edges of the pinna.  
 

Leather-leaf fern   Ngarara wehi

Pyrrosia elaeagnifolia (Pyrossia serpens)

 
Feels and looks like leather! A climbing fern most easily identified by its thick tongue-like fronds, whitish-fawn hairs on underside of frond  
 

Mangemange   

Lygodium articulatum

 
Not found in the Reserve.  
 

Rasp fern   Pukupuku

Doodia media

 
Ground fern whose older fronds have a scratchy/raspy feel to them. It is found abundantly through out the Reserve growing in dense mats, often near thread ferns. This fern produces hormones which mimic the hormones that control the development of insects.  
 

Ring or lace fern   Matata

Paesia scaberula

 
A yellowish fern found on the edges of the forest. It is recognised by the zigzag nature of the stipe. The lacy appearance belies the harsh "feel" of this fern.  
 

Rosy maidenhair fern   Puhinui / Tawatawa

Adiantum hispidulum

 
This fern has a stipe (midrib) which is dark brown and long. The frond is more oblong in shape and dark green in colour than the other maidenhair ferns found in the Reserve. The leaflets appear quite crowded on the frond compared to the common maidenhair fern  
 

Small maidenhair fern   Puhinui / Tawatawa

Adiantum diaphanum

 
This small fern tends to grow in mats on the flatter areas of the Reserve. In appearance it is very similar to Adiantum cunninghamii but the stipe is not as long and there is usually only three "blades" at the end of the stipe. The stipe does not have a hairy base.  
 

Thread fern   Panako

Blechnum filiforme

 
This fern is named for its long thread like fertile fronds which are high up in the tree tops in the Reserve (December). The more rounded leaflets form dense mats and in the larger mats some fronds show the more long elongated "leaflets". It can appear similar to the button fern (Pellaea rotundifolia) but the button fern is growing where it is more dry. This fern contains the same drug as used to lower blood cholesterol levels! (A.
