ITookeri(i\ mosses (Gepp). 295 



This species is allied perhaps to //. {Euhooheria) Preussu 

 described by Brotherus in Engler's Botan. Jahrb. xx. p. 201 

 (1894), and is distinct from it in having wider branches, longer 

 and more easily moistened leaves and probably larger areolation. 

 It is a larger plant than //. Breuteliana Hampe, and its leaves 

 are not half as wide as those of //. Vallis-gratice Hampe. 



HuiLLA. — A moss with leaves remarkably glaucnns and rather 

 fleshy in the living state ; rather rarely occurring on the ground by 

 oldish tree-trunks, in company with Utriculariie and Xyridese, etc., in 

 the spongy swamps on Morro de Monino at an elevation of 5400 ft. ; 

 without fr. April 1860. No. 39.

 XXI. ii. p. 442. t. V. fig. 5 (1872).' 



Lepidojnlum angolense Jaeg. Gen. et Spec. Muse. ii. p. 234 (1877). 



PuNGO Ando\c;o. — A very pretty terrestrial moss, occurring on the 

 shaded sides of springs and rivulets in almost entirely rocky places at 

 a considerable elevation ; but only in the Barranco de Pedra de S. 

 Antonio did Welwitsch gather it in a fruiting state, and that was on 

 mossy ground shaded by Vifathid unqulcuiiix and rarely conspicuous ; 

 with fr. May 1857. No. 108. 



Gor.uxGo Ar.To. — Apparently a rare and sporadic moss, occurring 

 among Hepaticsat the foot of tree-trunks very scantily in the primitive 

 woods of Quisucula near Bango-Aquitamba ; with poor fr. June 1856. 

 No. 193. 



3. H. contracta Gepp. sp. n. 



Monoicons ; green, dilute at apex ; yellowish at base. Branches 

 adscending, simple or laxly and irregularly pinnate, 2*5 to 7*0 cm. 

 long, complanate, with the foliage 3*5 mm. wide; branchlets 0-6 

 to 1"2 cm. long, obtuse. Lateral leaves reflexo-patulous, con- 

 tracted, unaltered when wet, variously flexed, asymmetrical, 

 2*0 mm. long by 0*6 wide, oblongo-lanceolate, acuminate; margins 

 elimbate, more or less infolded on one side and with a small 

 auricle at the base of the other (convex) side, strongly serrate 

 above the middle, with the subapical serrations geminate ; nerves 

 two, short, vanishing below the middle ; cells elongated (5 by 1 ), 

 contracted, densely chlorophyllose, with pellucid walls. Median 

 leaves shorter. Perichastial bracts smaller, more narrowly 

 acuminate, less strongly serrate, with subapical serrations 

 geminate. Seta 17 mm. long, smooth, red ; theca (unique, 

 damaged) inclined, oval?, with neck scaberulous, 'i as long; 

 operculum rostrate, \ as long. 



This plant is readily distinguished fi-om U. angolensis Welw. et 

 Duby by the less crowded, less imbricate, more flexuous, more 

 sharply acuminate leaves, the cells of which are contracted and 

 obscured by chlorophyll. In the apical leaves only do the cells, 

 when moistened, expand and become hexagonal and pellucid. 



PuNGO Andongo. — On shaded ground in the forest called " Mata 

 de Pungo" ; in small quantity and almost without fr. May 1857. No. 80. 



H. (inf/oleiitiiN and //. contracta present at first sight the appearance 

 of a Lejndojniuiii, but differ from that genus by having a Hookeriaceous 

 peristome and a, long smooth seta and leaves with abbreviated apical
