uring a short visit to the island of Jamaica in April 1906 

 I also stayed a few days in the Blue Mountains. Among other plants 



I collected some Mosses 

 there. These Professor 

 Brotherus in Helsingfors 

 has been so kind to de- 

 termine. 



Among these Mosses 

 there was a new species 

 of Anoectangium, namely 

 A. incrassatum Broth, 

 nov. spec, of which Prof. 

 Brotherus has sent the 

 following diagnosis and asked me to get it published : 

 Anoectangium incrassatum Broth, n. sp. 

 Dioicum; gracilescens, caespitosum, caespi- 

 tibus densissimis, fusco-tomentosis, laete viridi- 

 bus, opacis; caulis usque ad 3 cm altus, erectus, 

 dense foliosus, dichotome ramosus; folia sicca 

 adpressa, comalia spiraliter torta, humida erecto- 

 patentia, carinato-concava, lineari-lanceolata, bre- 

 viter acuminata, hyalino-mucronata, marginibus 

 erectis, integerrimis, nervo crassiusculo, infra summum apicem 

 folii evanido, dorso scabro, cellulis incrassatis, lumine minutissimo, 

 subrotundo, papulosis, pellucidis. Caetera ignota.
