After take a look to Jebb & Huxley revision (2019), I suppose it could fall into the variation of H. moseleyanum sensu Jebb & Huxley!

There's now a lot of synonyms, such as H. agatifolium which could produce such leaves...

Thank you for your comment.

But I don't look very much into the H. moseleyanum variety.
The branches are angular and the morphology of the tubers varies greatly, though it may be difficult to see in the photo.
I'll check it out when it blooms.

All large tuberous were overhead and could not be observed well.
The inside like a lattice is characteristic.

Very far, ambiguous and sorry...
But definitely think this species.

I think M. tuberosa.
Plobably ''pulvinata'' type. There are individual differences in spines development

Hi Akihiro,  These photos are just great!  Nice camera work.

I have grown most of the species of Lecanopteris in cultivation here in the US at some point over the last 15 years and I have never had an ant move into any of them - in my basement under lights or in a large greenhouse that also housed Rubiaceous ant-plants that have ants in them (the genus Cardiocondyle)

Looking over your photos I see no ants.  Have you observed ants in or on the Lecanopteris you have been photographing?

Thanks

Hi Frank,

Thank you.
I have observed Lec. sinuosa, lomarioides, cerebica, balgooyi, darnaedii, spinosa in the field so far.

The one with the fewest ants was darnaedii.

This is Lec. spinosa but there is a video. I strongly recommend you see it.

The largest species of Lecanopteris.
The leaf length is more than 80cm, and rhizome is more than 10cm wide.

A record of the growth rate of Lecanopteris balgooyi in Sulawesi.
I would like to continue observation if possible.

Tuber like ameba.
It seems to grow into a shape that some balls have gathered. The branches are angular.
Ant hole looks regular.

Have you checked it against this species.

Description. Tubers large (to 30x20 cm.), chambered and reminiscent of the amazing terrestrial species H. caminiferum in having chimneyed entrances, yet this species is epiphytic. Branches to 1m. long, flowers sessile in leaf nodes, with an iridescent quality, corolla rich in raphides, perianth in fours, fleshy and fragile. Corolla throats white-hairy, 5 mm across, with yellowish anthers.

 

Habitat/Range. Mid-montane primary forest on ridge of granites and volcanic sediments. On stunted, 10 m. (33 ft.) leaning Nothofagus (Southern Beech) trees, rooting on the underside of branches in moss. Trail from Andjai to Gunung (Mt.) Nettoti near Base Camp 2, at 1740 m. (5709 ft.) Kebar Valley, Manokwari District, West Papua Province, West New Guinea Island.

Infauna. Unknown but no ants recorded.

 

 

Hello Derick,

Thank you for the information.
I think so, too. Watch a little more growth.

It looks like epiphytic caminiferum.

It was falling in the forest.

Not Myrmephytum arfakianum. But very similar.

Hi Akihiro,

Welcome to the forum.  That is a great habitat shot of Lecanopteris balgooyi.  The thick spines replacing some of the fronds is something I like very much but the plants would not do that for me back when I grew these.  I was not very successful growing this species - the rhizome growing tip would always grow up and off of the growing media for me.

I am not clear why you do not think this is L. balgooyi?

Here is the description of balgooyi from Flora Malesiana, Series 2, Vol. 3, 1998, page 64.

It says the sori are "in a single row on each side of the rachis or costae, to 7 on each pinna" .  That is what I see on your habitat photo of the sporophyll.

I will admit to some confusion about this when I first looked at google images of L. balgooyi sporophylls.  Those photos (probably of plants in cultivation) show sporophylls that have complete margins or with only a little pinnatification of the frond.   The Flora Malesiana description allows for this saying the fronds are "entire to pinnatifid".  So I think better growing conditions in habitat are responsible for the different look of the sporophyll in your photo compared to google cultivated plant photos of balgooyi sporophylls..

Hi Frank,

I'm sorry for the delay in replying.

Thank you for the information.

Because of my poor English, I can not fully understand the meaning of research paper..

Your explanation really helped.

Sporophyll

Lecanopteris balgooyi?

Sporophyll is not balgooyi.
