100 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
35. SCAPANIA PORTORICENSIS, Hampe & Gottsche, in Linnzea, xxv. (1852), p. 342. 
Summit of Roraima, WeConnell & Quelch, 573. 
Not rare in the West Indian Islands, and found by Spruce also on the top of Mount 
Abitagua, 2000 m. (his Scapania splendida). 
36. PLEUROZIA PARADOXA, Steph., n. nomen.—Physiotium paradoxum, J. B. Jack, in 
Hedwigia, xxvii. (1886), p. 85.

37. HARPALEJEUNEA TENAX, Steph., n. sp. Sterilis, minor, fusco-olivacea, rigida, 
dense czespitosa. Caulis ad 15 mm. longus, capillaceus, parum ramosus. Folia 
remotiuscula, caule vix latiora, parum patula, cauli fere parallela, valde concava, in 
plano cordiformia, tertio supero abrupte angustata acuminata acuta vix incurva, 
` lobulo duplo angustiore, valde inflato, in acumen folii attenuato. Cellule foliorum 
parvee, ad 12 p, trigonis late confluentibus. Amphigastria parva, transverse inserta, 
caulem vix superantia subrotunda, appressa, integerrima. 
Roraima, Ledge, 7500-8000 ft., MeConnell & Quelch, 334j. 
A much reduced form, rigid and evidently well adapted to a dry climate, the leaves 
being very small, little projecting from the stem, the cell-walls very thick. This plant 
is almost unique in the great number of species of Lejewnea, which always live in damp 
and well sheltered places, and disappear where a dry atmosphere can reach them.
