A new species of Cheilolejeunea liverwort

For those interested in small plants, here's a new species of liverwort. Cheilolejeunea rodneyi is named after the Wellington Botanical Society stalwart Rodney Lewington.

Australian ferns with relatives in NZ

Here are a few species of Australian ferns that have close relatives in New Zealand. Can you guess the NZ relation?
More examples on the New Zealand Ferns facebook page, along with answers!

Ferns and lycophytes shared with Australia

I was fortunate to spend Christmas and New Year in Melbourne. Some 80-90 species of ferns and lycophytes occur naturally in both Australia and New Zealand. Below are a few examples of what we saw near Melbourne.
I have photos of many more such species on the New Zealand Ferns facebook page: https://www.facebook.com/nzferns/

A second species of Phlegmariurus

[From https://www.facebook.com/nzferns/]

New Zealand now has a second species of Phlegmariurus: Phlegmariurus billardierei. And it is an endemic - the only species of Lycopodiaceae that is found only in Aotearoa.

The spore-producing cones are the key to distinguishing the two Phlegmariurus species in New Zealand. In Phlegmariurus billardierei, the leaves immediately above the cones are appressed to the stems. In Phlegmariurus varius, the cones grade into spreading leaves.
In (A) is Phlegmariurus billardierei, with the spore-producing leaves of the cones at left, and appressed sterile leaves at right.

In (B) is Phlegmariurus varius, which always has at least some spreading spore-producing leaves (note the white discs - these are the sporangia). This means the cones seems less distinct than they are in P. billardierei.

Both species are widespread in New Zealand, and commonly grow together. Don't rely on overall form or habitat to tell them apart!

The name billardierei dates back to 1841, but it hasn't been in use for 35 years or more. We've newly moved it into Phlegmariurus.

For more details, you should be able to freely download a pdf from this link:
https://www.tandfonline.com/eprint/Q94TKDDGCFMWYK35SAG8/full?target=10.1080/0028825X.2019.1668438
(Email me if that doesn't work, and I'll send you the pdf.)

All of the plants below are Phlegmariurus varius. Even with the segregation of P. billardierei, P. varius continues to live up to its name.
Phlegmariurus varius can be a big, pendulous epiphyte, a gracile epiphyte, or a stout, upright terrestrial plant (especially in alpine areas).

Hiya distans, a new name for the fern previously called Hypolepis distans

It turns out that Hypolepis distans is not closely related to the other species of Hypolepis. This blog post sets out the case for instead calling it Hiya distans.

https://blog.tepapa.govt.nz/2018/10/12/new-zealand-gains-a-fern-genus-named-after-the-chinese-imperial-guard-hiya/

I'd appreciate feedback on whether people think we should adopt this change on iNaturalist. I recommend we do wait until/if it is picked up by the New Zealand Plant Names Database

Why do scientific names change? Kiokio and the other Blechnum ferns as a case study

Do scientific names change too often? I think they sometimes do.

I explore this question in this Te Papa blog post: Why do scientific names change?

I'm keen to hear what you think. Please leave a comment at the bottom of the Te Papa blog post. How much taxonomic change do you like ?

The Blechnum ferns make an interesting case study in this respect. One approach sees Doodia move into Blechnum; the other approach keeps Doodia but splits Blechnum into many genera.

For instance, Blechnum fluviatile or Cranfillia fluviatilis? Blechnum filiforme, or Icarus filiformis?

New fern and lycophyte eFloraNZ chapters published

Very pleased to share four recently published chapters from the Flora of New Zealand - Ferns and Lycophytes: Aspleniaceae, Dennstaedtiaceae, Tectariaceae, and Selaginellaceae.

pdfs are freely downloadable from: http://www.nzflora.info/publications.html

How tall can Blechnum fraseri get?

Te Papa's Pat Brownsey is beginning to draft the eFloraNZ treatment for Blechnaceae, and he wants verified minima and maxima for quantifiable characteristics. We estimate the plant with me in the picture is c. 900 mm, which is the tallest we know of. Please tell me if you know of taller (preferably with pictures uploaded to NatureWatch!).

Please record even common species like bracken

Pat has nearly completed the draft for the eFloraNZ chapter of the Dennstaedtiaceae ferns (native genera are Histiopteris, Hypolepis, Leptolepia, Paesia, and Pteridium). It will shortly join the Aspleniaceae chapter in peer review. All going well, both should be published by the end of 2017.

From the Dennstaedtiaceae chapter, here is a draft map for bracken, Pteridium esculentum subsp. esculentum:

Map CC BY Landcare Research.

Each blue dot is a specimen at Te Papa, Auckland Museum, or Landcare Research. Though these are New Zealand's three major herbaria, I reckon these collections are under-representing the abundance of bracken. For instance, I suspect inland areas of the South Island and the east coast of the North Island are not genuine areas of sparseness for bracken.

The same is true for NatureWatchNZ: see the map for bracken https://inaturalist.nz/observations?place_id=6803&taxon_id=194768

Which makes this a plea to record observations of even common species like bracken!

Using tools like NatureWatchNZ, everyone can help New Zealand accurately document its biodiversity.

Bring on the bracken observations...

Lycopodiella diffusa and L. lateralis - are they different?

The lycophytes Lycopodiella diffusa and Lycopodiella lateralis are sometimes easy to distinguish and sometimes not! We want to determine if they really are distinct species. Pat Brownsey is just beginning to draft the eFloraNZ treatment for the Lycopodiaceae.

You can help us - please add photos to NatureWatchNZ if you see Lycopodiella diffusa or L. lateralis (or something in between).

For more details (and photos), please see: https://inaturalist.nz/projects/lycopodiella-diffusa-and-lycopodiella-lateralis-are-they-really-different-species


The two apparently in sympatry, with Lycopodiella diffusa at left and L. lateralis at right, near Charleston.
