26. MICROPTERYGIUM GRANDISTIPULUM, Steph., n. sp. Stevilis, minor, dilute brunnea 
vel flavo-rufesceus, muscicola, valde intricatim c:espitans. Caulis tenuis, ad 2 cm. 
longus, irregulariter ramosus. Folia conferta, decurvula, semiamplexicaulia, ex 
angusta basi ovato-oblonga, longe acuminata, apice abrupte attenuata ibidemque 
paucidenticulata vel integerrima. Folii lobulus posticus integerrimus, brevi spatio 
(ad 1) carinatim coalitus, folium subinde oblique percurrens, attenuatus, longe sub 
foli apice desinens. Cellule foliorum leves, 8x12 jp, basales 8x17 n sub- 
rectangulatz, maxime equaliterque incrassatz. Amphigastria magna, imbricata, 
foliis parum breviora, transverse inserta, plana, integerrima, medio infero fere 
circularia, superne abrupte angustata, lanceolata, acuta. 
Roraima, Ledge, 7500-8000 ft., McConnell & Quelch, 334/14 in part. 
There is not a species of this genus which does not have some of its leaves merely 
conduplicate, the wing being entirely wanting; where the latter is developed it is part 
of the antieal lobe, which can easily be observed if a transverse cut of the leaf is made ; 
the same occurs sometimes in Scapania, and is best developed in Schistochila. 
27. MIcROPTERYGIUM PTERYGOPHYLLUM, Spruce, in Trans. Edinb. Bot. Soc. xv. (1885), 
p.384. Jungermannia pterygophylla, Nees, in Mart. Fl. Bras. vol. i. pars prior, 
Algse, Lichenes, Hepatieze, p. 377. 
Summit of Roraima, McConnell & Quelch, 530 in part. 
Common in Tropical America. 
28. Leprpozia COMMUTATA, Steph. in Hedwigia, xxvii. (1888), p. 293. 
Summit of Roraima, McConnell & Quelch, 521.
