Re: self heading Philodendron ID

---

Dear All,

 

          Here are the illustrations from Exotica.  P. eichleri is presented as a species, while it's supposed hybrid with P. undulatum is at right.

Dear Eric,

 

Aloha.  I agree with Julius on all counts.

 

Philodendron undulatum is very distinctive with

numerous, persistent, needle-like , half inch to three

quarter inch, intravaginal squamules on the stem.  It

is very different from the plant I know as P.

eichleri.

 

Literature on Philodendron eichleri is as follows: 

 

P. eicheri in Bot. Jahrb. 26 : 556 (1899); Krause in

Engler, Das Pflanzenreich 60 (IV. 23Db): 133 (1913).

Types: Brazil, Minas Gerais state, Carandai, cult.

Brazil, 15 Nov. 1887 at Quinta da Boa Vista, Rio de

Janeiro as no. 67, Glaziou 16503 (infl.,B!

syn.;sterile, P! isosyn.), Glaziou 17332, (sterile, B

syn. not seen; C! K! P! isosyn.). 

 

If someone in virtual world has access to the original

description in Das Pflanzenreich to scan and

share...all of us can compare our plants and decide

what that taxon / hybrid is, within the confines of

the original intent.  I have seen plants of

Philodendron labeled as eichleri...it is a massive

plant that has affinities to Philodendron speciosum.

The spathes are green with pink edges, and the stem

has light colored petiole scars...off hand I could not

tell you the nature of the intravaginal

squamules...but I can check in the next few

days....there is a large clump about a mile from me.

However, until I can compare the original description

and translate the German...it is impossible for me to

tell why Simon Mayo considered this a synonym of

Philodendron undulatum....perhaps what we consider

Philodendron eichleri is faulty or perhaps the

original description is vague and the type specimens

compare favorably with P. undulatum.  Questions.

 

Aloha,

 

Leland
