248 LICHENES HIMALAYENSES. 
16. Parmelia perlata, Ach. 
Has. Garhwál; on bark; fertile (thallus smooth-edged, ample). Ka- 
rim Pass, Kumaon, alt. 7500 feet ; fertile (edges of thallus pulverulent ; 
habit that of Cetraria glauca, Ach.). 
Parmelia perlata, var. saccatiloba, Bab. MSS. P. saccatiloba, Tayl.! 
in Hb. Hook. (nuda); et P. cristifera, ejusd.! 1. e. (sorediis marginalibus 
insignis — P. perlata, v. grandis, Laur.! in Linnæa, 1837, p. 45.) 
Has. Chinar, Kumaon, alt. 8700 feet; Gori River, Kumaon, alt. 
4700 feet; barren in both localities. 
Differs from P. perlata, Ach., in nothing but its ample size; the spe- 
cimens which I have seen are from tropical and subtropical countries, 
and barren. The Himalayan plant is without soredia. The sorediated 
form (P. cristifera, Tayl.!) bears glomeruli so copiously, that the ap- 
pearance of the plant resembles that of Sticta glomulifera, Del. 
17. Parmelia levigata, Ach. 
Has. Chinar, Kumaon, alt. 8700 feet; fertile. (Coll. n. 4.) 
These specimens are a little different from the common form: their 
upper surface more resembles P. physodes. 
18. Parmelia caperata, Ach. 
Has. Chinar, Kumaon, alt. 8700 feet; on rock; barren, and much 
sorediated. (Coll. n. 3.) 
19. Parmelia (Physcia) cirrhata, Fries, Syst. Orb. Veg. p. 283. 
Has. Chinar, Kumaon, alt. 8700 feet ; on sticks; fertile. 
Habit of Ævernia furfuracea, Fries. The same plant has been 
gathered in Nepal by Wallich. From the description of Fries (wé 
supra) and his remarks (Lich. Europ. p. 76) there is little doubt that 
his plant (from Nepal) is the same as ours. (Coll. n. 22.) 
20. Parmelia leucomela, Ach. 
Has. With the preceding ; fine and fertile, growing on the ground 
apparently, among leaves (of Rhododendra ?) and fragments of a ni 
donia (C. perfoliata ? Florke — C. perfilata, Hook.). 
21. Parmelia speciosa, Ach. 
Has. Gori River, Kumaon, alt. 4700 feet; on rock. Chinar, 
Kumaon, alt. 8700 feet; on bark. Fertile in both localities. (Coll. 
n. 17.) 
22. Parmelia stellaris, Ach. 
Has. Shelong, Kumaon, alt. 13,000 feet; fertile. (Coll. n. 32 
pr. p)
