It will save space and repetition to mention that of the locali- 
ties quoted below, Monchique, Caldas (de Monchique), Foya, 
Picota, Silves and Portimâo are in Algarve; Cintra, Eugaria and 
Colhares in Estremadura; and Coimbra, Louza and Bussaco in 
Beira. (cfr. — fruiting; st. = sterile). 
* Catharinea angustata var. rhystophylla (CG. M.) Dixon (C. 
rhystophylla C. M.) Chestnut woods, Monchique. Woods, Bussaco. 
Both cfr. Most or all that we saw in Portugal ofthis species seemed 
 referable to the variety. It is probably due to response to xero- 
phytic conditions, judging from its distribution as known to me. 
* Polytrichum nanum Neck. Monchique; cîr. 
* Pol. formosum Hedw. Peaty hollow near summit of Foya; st. 
Ditrichum subulatum Hampe. Frequent in rock crevices and 
on banks in the neighbourhood of Monchique; cfr. 
Ceraltodon chloropus Brid. Among boulders, Caldas; cfr. 
C. corsicus Schp. Picota. We gathered this plant among bare 
rocks on the summit, whence it is recorded by Solms-Laubach, 
and again on lower ground on the same hill. The latter plant had 
the peristome almost unbordered, but in the former I find a 
distinct though narrow pale border. It is at the best, think, but 
a rather poorly marked var. of C. purpureus.
