The first author studied the bryophyte communities on the East slope of Mt. Kenya through the forest belt between 1600 and 3000 m elevations. Seven sampling plots were selected at each 200 m altitudinal interval. At each sampling plot microclimate data measurements were carried out for six months between July and December 2020 using dataloggers and the composition of epiphyllous communities was studied in details with special reference to the host plants. Tamás Pócs and his team (Bence Együd, Judit Havasi and Mária Szegedi) joined to this research during the August of 2021, to help in further collection and identification work. The collected specimens are deposited in the herbaria of EA and EGR. Majority of the collections have already been identified. The discovery of the only mainland African occurrences of the Lemurian Microlejeunea inflata and Leptodon fuciformis are outstanding results. Other species are new for Kenya: Cololejeunea platyneura, Cyclodyction subbrevifolium, Diplasiolejeunea deslooveri, Fissidens intramarginatus and Telaranea coactilis. The last author visited the same sites 2004 with his late wife, Sarolta Czímer, guided by Min S.Chuah-Petiot from Nairobi University and from their collection Gemmabryum subapiculatum, Orthotrichum denticulatum, Lophocolea fragrans and Lophocolea muricata proved to be new to Kenya.

Radula grandilobula Promma & Chantanaorr. (Figs 11E, F; 14) Cryptogamie, Bryologie 36 (3): 219 (2015). SPECIMEN EXAMINED. — Malaysia. Terengganu: Mt. Tebu Forest Reserve, 15 km S of Jerteh town.

REMARKS Radula grandilobula is close to the widespread Indopacific R. acuminata (Zhu & So 2001); differs in having triangularovate leaf lobes, frequently recurved free margin of leaf lobules, the leaf lobule apices pointing towards the leaf lobe apices or directed away from the stem, and the finely segmented oil bodies, 2-4 per cell (Promma & Chantanaorrapint 2015). Radula grandilobula was first described in Nakhon Si Thammarat, southern Thailand (Promma & Chantanaorrapint 2015), and its occurrence in northern Malaysia was therefore expected.

Tebu Forest Reserve, 15 km S of Jerteh town. Primary lowland dipterocarp forest with small waterfalls and slow stream.

REMARKS Colura inuii is very similar to the widespread Indopacific C. conica (see Zhu & So 2001) but in the latter species, the sac always has a crested, toothed apiculus whereas in C. inuii, it does not occur. The perianth keels of C. conica have 1-3 celled sharp teeth at the end of the wings (Jovet-Ast 1953, fig. 51: 1-3) whereas in C. inuii, the perianth keels are often strongly mamillose but teeth are never produced. Moreover, the oil bodies are homogenous (smooth externally, rarely segmented into indistinct granules) in C. inuii while granular (faintly rough externally) in C. conica (seeYang et al. 2013: figs 2g, 3e). Furthermore, both species can be distinguished by the presence of 18-20 median valve cells and 17-19 surrounding hyaline cells in C. inuii while 13-17 and 15-16 in C. conica. Colura inuii was known from China (Taiwan), Japan and Vietnam (Horikawa 1931; Zhu & So 2001; Shu et al. 2017). New to Malaysia, which record in Peninsular Malaysia represents its southernmost locality, extending to the Malesian region. The species usually grows on living leaves, rarely on bark and can be considered, as typical epiphyll; in Malaysia it was found on living and dry fallen leaves in a lowland dipterocarp forest and also in montane forest, above 750 m alt., Published as part of Sarimi, Muhammad Syafiq, Pócs, Tamás & Lee, Gaik Ee, 2021, Data to the Malaysian liverwort flora, III: New Lejeuneaceae records from Sabah and Peninsular Malaysia, pp. 249-267 in Cryptogamie, Bryologie 20 (19) on pages 254-255, DOI: 10.5252/cryptogamie-bryologie2021v42a19, http://zenodo.org/record/7822391, {"references":["ZHU R.
