SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 



LEUCODONTACEAE 



ANTITRICHIA KILIMANDSCHARICA Broth. 



Heath Zone; Nos. 3413d, 3756, 3758b, 3772. No. 3756 is in 

 g-ood fruit, which has not been described, but I do not find any differ- 

 ence from that of A. curtipendula. The others are sterile. 



NECKERACEAE 



NECKERA PLATYANTHA (C. M.) Par. 



Heath Zone, principally; Nos. 3443, 3449, 3754, 3756f, 3759; 

 mostly c. fr. The perichaetial bracts may be three times as long as 

 the capsule, which, however, is not always concealed, as it may pro- 

 trude laterally from the perichaetium (Cf. pi. I, fig. 6). 



NECKERA SUBMACROCARPA Dixon, sp. nov. 



(PI. I, fig. 7.) 



Habitu foliisque N. platyantkae (C. M.) et iV. macrocarpae Broth."" 

 simillima, huic quoque speciei cauli paraphylliis numerosis praedito 

 similis et afifinis, fructu tamen longe aliena. Perichaetium 8-10 mm. 

 longum, bracteis externis thecam longe superantibus. Theca im- 

 mersa, vel saepe e perichaetio lateraliter emergens, e seta pro more 

 praelonga, 2-2.5 "i^^"'- ! theca 2-5 mm., aurantiaca ; operculum conicuni 

 breviter curvirostratum. Peristomii dentes longi, angusti, supra 

 dense tenereque infra grossius papillosi, non striolati, intus trabecu- 

 lati ; endostomii membrana perbrevis, pallida, laevis ; processus 

 anguste lineares, circa dimidiam partem dentiuni longitudinis 

 aequantes, pallidi laeves, carinati, baud rimosi, plus minusve nodosi. 

 Spori 25-30 IX. 



Hab. : Heath Zone, 12,000 ft., epiphytic; No. 3443b. 



Diimmer writes on the label " Frequent " ; but this is by confusion 

 with A^ platyantha, which in habit is identical or nearly so ; the two 

 were growing intermixed, and the Washington specimen under this 

 number was entirely A^. platyantha, which is evidently a frequent 

 moss on Mount Elgon, in the Heath Zone. 



At first sight the fruit of the two species does not show" any great 

 dift'erence, but on examination it will be seen that in A^ platyantha 

 the capsule is almost sessile and is hidden at the base of the peri- 

 chaetium, with the bracts two or three times its length ; in A'^. sub- 

 macrocarpa the capsule itself is about the same length, but both
