 laxi viridissimi supra pollicares; caulis crassiusculus flexuosus apice 

 falcatus inferne nigrescenli-tomentosus ; folia caulina siccitate et

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. 

 ait., inter Leucobryum : idem in Hb. Jamaic. N° 11,008. 



Ad Campylopodes capitiflores pertinens, species distincta robusta. 



16. Dicranum (Leucolomata cespitulantia) longicapillare 



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

 tate et madore patula directione varia disposita nec secunda, e basi 

 cellulis alaribus multis Iaxis fuscis vel hyalinis eleganter ornata in 

 laminam anguste oblongo-acuminatam longissime subulatam sum- 

 mitate parum denticutatam pallidam attenuata parum involutacea, 

 limbo usque ad medium folii vel ultra lato hyalino marginata inde 

 usque ad subulam supremam angustissime marginata,infra e cellulis 

 minutis angustissime ellipticis incrassatis subpunctiformibus areo- 

 tata, nervo angusto hyalino excurrenle carinato-exarata. Csetera 

 nulla. 



Habitatio. Jamaica, Morces Pass, 4900 ped. ait., 24 IV 1896 : W. Harris 

 legit frustula inter Punyentellam patentem. 



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

 minor i bus angustioribus, basi reflexis, cellulis alaribus multo minoribus, limbo 

 vix ultra medium folii excurrente multo angustiore.
