NO. 8 UGANDA MOSSES — DIXON 9 



ter plicata, sicca flexuoso-incurva, integra, marginibus subplanis, 

 costa infra apicem desinente. Folia ramulina dense conferta, madida 

 subcomplanata, ovato-elliptica, subobtusa, costa angusta, sub- 

 pellucida, longe infra apicem desinente ; cellulis minutis, irregulariter 

 hexagonis, 4-5 fx latis, humiliter papillosis ; marginibus crenato- 

 serrulatis. 



Autoicum. Folia perichaetialia externa aristata, rigide patentia 

 vel subsquarrosa, interna erecta, in acumen loriforme rigidiusculum 

 subintegrum producta, intima ciliata. Seta 1.5 cm., tenuis, pallide 

 aurantiaca, laevis. Theca subpendula, breviter ovato-elliptica, 

 gibbosa, operculo e basi plano-convexa breviter recte rostellato. 



Hab. : Tree trunk in forest, Kipayo, alt. 4,000 ft., March, 1914, 

 Diimmer 719. 



A very pretty and distinct species, with the dense plumose habit 

 more nearly of T. plumulosum (Doz. & Molk.) than of any of its 

 African allies ; it is indeed very similar in appearance to the more 

 slender forms of that species. T. ramusculosum (Mitt.) is of quite 

 a different order. 



HYPNACEAE 

 ECTROPOTHECIUM DUMMERI Dixon, sp. nov. 



Caespites densissimi, sordide virides, nitidiusculi. Caules dense 

 intricati, densiuscule irregulariter subpinnatim ramosi, pergraciles, 

 ramis circa 3-5 mm. longis, complanatis. Folia complanata, valde 

 patentia, nee falcata, parva, caulina circa 0.5 mm. longa, ovato- 

 lanceolata, sensim breviter acuminata ; ramea minora, ovata, breviter 

 oblique acuminata, vel acuta; marginibus planis, integris vel incon- 

 spicue denticulatis, costis nullis. Areolatio sat laxa, e cellulis lineari- 

 rhomboideis, valde prosenchymaticis, 5-7 /x latis instructa, basilaribus 

 unica serie latioribus, ellipticis, subvesiculosis, alaribus vix ullis. 



Autoicum. Seta tenuis, circa 1 cm. longa, laevis. Folia peri- 

 chaetialia erecta, sensim longe rigidiuscule acuminata, subdenticulata. 

 Theca minuta, vix 1 mm. longa, turgide ovata, horizontalis, postea 

 pendula ; operculum conicum, siccitate conico-rostellatum. 



Hab. : Damp soil in forest, Nagoye, alt. 4,000 ft., Jan., 1917, 

 Diimmer 3050a ; c. fr. 



A distinct species, with much shorter and wider leaves, wider cells, 

 and darker color than the allied African species, which for the most 

 part have finely acuminate leaves and very narrow cells. The pres- 

 ent plant is vegetatively much more like an Isopterygium, but the 

 subglobose, pendulous capsule is quite ectropothecioid.
