 laxi viridissimi supra pollicares; caulis crassiusculus flexuosus apice 

 falcatus inferne nigrescenti-tomentosus ; folia caulina siccitate et 

 humore patula apice in comam reduncam breviter caudatam unci-

 nervo lamellaceo-slriato in subulam elongatam denticulatam canali- 

 culatam excedente lato-exarata, e cellulis ellipticis in membranam 

 viridem nilidulam incrassatis areolata; perichcetialia similia longiora 

 patula; theca in pedicello breviusculo flavocurvato flexuoso inclinata

Habitatio. Jamaica, Morces Pass, 4900 ped. altum, in solo sylvestri, 24 Apr. 

 1896 : W. Harris in Hb. Jamaicensi N 10,040 ; Newhaven Pass, 5400 ped.

Ad Campylopodes capitiflores pertinens, species distincta robusta. 



16. Dicranum (Leucolomata cespitulantia) longicapillare 



n. sp. : caulis humilis parce divisus horridifolius; folia caulina sicci- 

 late et madore patula direclione varia disposita nec secunda, e basi 

 cellulis alaribus multis laxis fuscis vel hyalinis eleganter ornata in 

 laminam anguste oblongo-acuminatam longissime subulatam sum- 

 mitate parum denticulatam pallidam atlenuata parum involutacea, 

 limbo usque ad medium folii vel ullra lato hyalino marginata inde 

 usque ad subulam supremam angustissime marginata,infra e cellulis 

 minulis angustissime ellipticis incrassalis subpunctiformibus areo- 

 tata, nervo angusto hyalino excurrenle carinato-exarata. Caetera 

 nulla.

 legit frustula inter Pungentellam patentem. 



L. albulum Sulliv. Cubense habitu simile et proximum differt : foliis multo 

 minoribus angustioribus, basi refiexis. cellulis alaribus multo minoribus, limbo 

 vix ultra medium folii excurrente multo angustiore.
