4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 69 



Pilotrichclla tenellula (C. M.) and P. capillicaulis (C. M.) may be 

 near it, but the author describes the leaves as shortly pointed, ap- 

 parently in reference to the stem leaves. P. pscudoimbricata C. M. 

 is also somewhat like it, but the stem leaves are more shortly and 

 rigidly pointed, the branch leaves more erect, etc. 



NECKEROPSIS TRUNCATA, (P. Beauv.) Fleisch. 



Tree trunks in forest, near Nagoye, alt. 4,000 ft., Dec, 191^, 

 Diimmer 3028. 



A sterile plant, probably referable here. Ncckcropsis subtnincata 

 Broth, from Togoland I do not know ; but it appears to be an unpub- 

 lished species. 



NECKEROPSIS LEPINEANA (Mont.) Fleisch. 



Epiphytic in forest, Mabira, near Mubango, alt. 4,000 ft., Jul}-, 

 1916, Diimmer 2962. Locally abundant.

This agrees quite well with an original specimen of Laurent's 

 gathering from the Belgian Congo, in Herb. Besch. at the British 

 Museum. It has not hitherto been recorded in fruit. Sporophytic 

 characters to be noted are as follows : 



Perichaetia numerous ; bracts rigid, subsquarrose, broadly 

 acuminate, subentire, thinly nerved ; vaginula and paraphyses some- 

 what exceeding the perichaetium. Seta 1.5 cm., yellowish, slender. 

 Theca erect, symmetrical ; lid rostrate. External peristome pale ; 

 teeth hyaline, very narrow, rather closely trabeculate, striolate only 

 in the lowest segments, above finely papillose ; internal orange brown, 

 from a low basal membrane ; processes nearly equal to the teeth, 

 rather robust, rigidly linear, narrowly and interruptedly slit for the 

 greater part of their length, finely papillose, nodose. Cilia appar- 

 ently none. 



PINNATELLA ENGLERI Broth. 



In small quantity, associated with the last species. Also on trees,
