4, PoRELLA MULLERI (Gottsche). 
Madotheca Miilleri Gottsch. Mex. Leverm. 153. 
Hab. Andes Quitenses, in valle Alausi, loco Lucmas, alt. 2000™, e ramis 
pendula, sterilis. Mexico, in monte vulcanico Orizaba (FR. MULLER). 
F. tob 20x11, lobulus -75x'3; c gy; f*% °85x°4. (sine bast 
decurrente). 
Elata pallide viridis. Caules 5-6-pollicares pinnati; rami dissitiusculi 
elongati subzequilongi, raro iterum pinnulati. 
Folia subdissita, ramorum contigua vel basi parum imbricantia, ad basin 
fere usque bipartita, ad sinum integerrima ; lobus oblique ovato- 
rhomboideus, abrupte oblique apiculato-acutus, basi antica semicor- 
datus, margine sinuato-repandus apicem versus subdenticulatus, 
margine postico infra medium recurvus sed non crispatus ; lobulus 
triplo fere minor, obliquus, angulum 30° cum caule efformans, ligu- 
latus vel lgulato-lanceolatus obtusatus, margine sinuatus, basi cris- 
tatim decurrens ; cellule parvule rectangulari-hexagonz subopace, 
ad angulos parum incrassatz, basales majores flavidee. Folia siccando 
margine postico valide convoluta. 
Foliola subimbricata ligulata retusa, basi in cristam plus minus laciniatam 
longe decurrentia ; alia media basi radicellifera. 
A P. ptilopsi differt ramis distantibus subsimplicibus, foliis apiculatis 
subdenticulatis, lobulis brevioribus subdivergentibus, ete.—Mad. Chilensis 
L. et Ldbg. distare videtur caule humiliore vage pinnato ; foliis arcte 
imbricatis integerrimis ; foliolis haud basi cristato-decurrentibus.—M. 
Miillert G. autem, Mexicana, ad amussim fere cum nostra Andina congruit.
