FRANK  what is this  book?

SATOSHI  it's a shame no flower .

but  may be these caracters here  :

Flowers clustered, about 5 mm high, nesting in axillary cushion-shaped tubercles, with very short membranaceous bracteoles at the base and surrounded by reddish hairs

are more discreminate.

Bonjour

for me the clypeoli is not indistinct  ( with spine on it)  alveoli is not circular  with  no dense spines around ; more close 'salomonensis '  no

it 's a shame  no  macro from the inflorescence  : to see the ring hair ,  the anthers and the stigma position in the corolla

jeff

Bonjour

DERRICK    why this URL ?

JEFF

Bonjour

do you know this document  to lecanopteris

http://homepages.caverock.net.nz/~bj/fern/lecanopteris.htm

jeff

with  the new revision to B.Swale and M. Hassler  to 20-07-2001 

we speak just to Lecanopteris

Lecanopteris Reinwardt 1825

Myrmecophila cHRIST 1897

Myrmecopteris  Pichi Serm 1977

may be here also some anteriory problem?

perhaps a DNA analysis to decide is not a luxury !!!

jeff

Bonjour

a Microgramma list here http://en.wikipedia.org/wiki/Microgramma_%28plant%29

all have not some tuber ,just solanopteris  no ?

S.brifons and S.tuberosa should not be included in the list

jeff

you find this one  in  molucca and the north west  to the irian jaya  in vogelkop   may be in sulawesi there are .

with these orange petiole, there are not a lot of specie !!

jeff

when you are  not in their  growing area , difficult  to see these plants 'in situ'  , just one solution , trade or swap 

for me ANDREAS  these rules are OK.

jeff

Bonjour

have you try some spore sowing?

ROBBIN C MORAN  to the missouri botanical garden  made a very good article on potato fern.

S.brunei  is find on Costa rica -Panama-Colombia -Ecuador

S.bismarckii and S. tuberosa Ecuador and Peru (1100 to 2000m)

S.brifons  in amazonia  lowlands of Colombia,Ecuador-Peru (200 to 800m)

microgramma and solanopteris  are sister genera  not the same

microgramma : "lacks tubers, has narrowly lanceolate scales on the rhizomes, smooth or wartyspores and usually lacks hairs among the sporangia "

solanopteris :"tubers,small,round scales on the rhizomes, spinyspores,and slender club-shaped hairs among the sporangia "

jeff

magnifique

it  seem  to be S.thekii ,  their distribution stem is very differente than these others 2 ( or 3).

jeff

OK , but in the "flora vitiensis nova "  we find  these 2   S.imberbis and wilsonii    in malesia 2  also.

S.imberbis : "epiphytic srub  with short branches arising from ant-inhabited tubers , sparingly know  at elevation up to 430m in dense forest , with white corollas , the only dated specimen  bore flowers and fruit in may ".

Huxley & Jebb  find some difference  but for they  due to developmental stages or the vagaries of drying .

where is the truth ? 

jeff

may be a M.platytyrea subsp platytyrea ?

magnifique  these red -orange petiole .

you have find this specie at what altitude in sulawesi ? mangrove ,coastal savanna ?

jeff

Bonjour

MAGNIFIQUE  

I had seen these plants just  on drawings

have you seen ,may ,be a difference with a S.wilsonii   and have you seen  S.thekii

merci

jeff

may be some guy grow these plants

in what condition ( watering-substrat- sunlight- fertilizer-etc)

thanks for yours answers
