We describe the new liverwort species Cheilolejeunea schiavoneana M.E.Reiner & Gradst. from submontane rainforest in the Western Cordillera of Colombia. The new species is related to C. adnata (C. sect. Cheilolejeunea) but differs by larger plant, leaf and underleaf size, robust stems, a 5-6 cells wide ventral merophyte, abundance of microphyllous branches, and vegetative reproduction by caducous leaf lobes produced on flagelliform shoots. The latter feature is characteristic of the genus Rectolejeunea and its presence in Cheilolejeunea is apparently a case of parallel evolution. The discovery of C. schiavoneana adds a further endemic taxon to the rich flora of the Colombian Western Cordillera. Key

Abstract We describe the new liverwort species Lejeunea ryszardii from montane rainforest in the Central Cordillera of Colombia (Dept. Quindío) and Rectolejeunea halinae from submontane rainforest in the Western Cordillera (Dept. Risaralda). Both species stand out by copious vegetative reproduction via caducous leaves. Lejeunea ryszardii resembles the Caribbean L. paucidentata in the leaf lobes with toothed margins and a narrow base but strikingly differs from the latter species in: 1) leaf margins with mamillose cells, which are sometimes crowned by a small papilla, and with scattered rhizoids with or without a tooth-like base; 2) lobules with narrowly elongate, curved, sharp tooth; 3) stem epidermis brownish and somewhat thick-walled; 4) copious production of caducous leaf lobes. Moreover, L. ryszardii is dark green to brown in color and probably dioicous while L. paucidentata is light green and autoicous. Rectolejeunea halinae resembles the neotropical R. flagelliformis in having ciliate caducous leaves but clearly differs from the latter in the pointed leaf tips, the presence of ocelli in underleaves, and the flagelliform shoots with flat, entire-margined underleaves. The discovery of these new species adds two further endemic taxa to the rich bryophyte flora of the Colombian Andes.

G-BOIS (“Flora Orientalis Herbarium”), the result of many years (1844–1888) of titanic work by an outstanding botanist from Geneva Pierre-Edmond Boissier, is the most important taxonomic and nomenclature source of data on the rich flora of the territory from Greece to Middle Asia and the borders of India. It was isolated from an extensive Boissier’s private herbarium after the latter was included in the collection of Conservatoire et Jardin Botaniques and kept in a special underground bunker. A material for 366 species and 47 infraspecific taxa of the Umbelliferae is stored in G-BOIS. Among lectotypes, the vast majority relate to the Boissier taxa; a small minority belong to taxa of other authors (their types and lectotypes are in other herbaria). The materials of other herbaria, Geneva and non-Geneva (Geneva General Herbarium, De Candolle Prodromus Herbarium, K, LE, P, JE, W, B and others) were also checked. Among the Umbelliferae material kept in G-BOIS, lectotypes of 255 names were designated here and those of 107 names have been designated before, including lectotypes selected prior 2011 as types and holotypes which were corrected to lectotypes (89 names). Besides the designated lectotypes and isolectotypes, G-BOIS also contains holotypes of 44 Boissierian Umbelliferae names and syntypes of 81 names. Additionally, holotypes, lectotypes and isolectotypes (in total for 168 names) were revealed in Geneva General herbarium (G). One new species name (Prangos iranica nom. nov.) has been proposed here in the genus Prangos.

A New Species

An intensive exploration of the páramos ecosystem on northwestern Colombia allowed the discovery of a new species of Espeletia (Millerieae: Asteraceae), E. restricta. Espeletia is an endemic taxon to the páramos of Colombia, Venezuela and Ecuador, generally found above 3000 m of elevation. Espeletia restricta has a very narrow distribution limited to the northern Central Cordillera of Los Andes. The new species is similar to Espeletia occidentalis, species occurring in the Central and Western Cordillera, from which it differs in  the size of its synflorescences relative to the rosette length (less than 1.5 times longer than the rosette vs. 2–3 times longer than the rosette) and indument colour (yellowish vs. greenish-white). The new species was assessed Critically Endangered (CR) due to the small size of its population and the restricted nature of its occurrence, which makes this taxon of great conservation concern.

The caucasica species group in the subgenus Lunatipula is redefined and now consists of five species native to the Caucasus. Tipula (L.) eleniyasp. nov. is described as new to science, and variations in the male terminalia in two populations are noted. Two subspecies (quadridentataquadridentata and quadridentatapaupera) are elevated to species rank. Detailed photo’s complement the descriptions of all five species (caucasica, eleniya, paupera, quadridentata, talyshensis), and data on ecology and distribution patterns are included as well as identification keys to males and females. Tipula caucasica is recorded from the West Caucasus and Tipula quadridentata is recorded from Dagestan (Russia) for the first time. Parallel evolution is traced in the male terminalia of the new species and in several non caucasica species group of Palaearctic Lunatipula.

A New Species

A new species of the gekkonid genus Cnemaspis is described based on a series of nine specimens from near Sankari in Salem district, Tamil Nadu state, southern India. The new species is diagnosable by the following suite of characters: a small-sized Cnemaspis (adult snout to vent length less than 33 mm); heterogeneous dorsal pholidosis consisting of weakly keeled granular scales intermixed with large strongly keeled, conical tubercles, 9–11 rows of dorsal tubercles, 12–17 tubercles in paravertebral rows; spine-like scales absent on flank, 17–20 lamellae under digit IV of pes. Males with 4–6 femoral pores on each thigh, separated on either side by eight poreless scales from four precloacal pores; precloacal pores separated medially by a single poreless scale; two single dorsal ocelli on occiput and between forelimb insertions, two pairs of ocelli on either side just anterior and posterior to forelimb insertions. Cnemaspis agarwali sp. nov. is the fifth endemic species of Cnemaspis from peninsular India outside the Western Ghats and highlights the rich and unique diversity of this understudied region.

Loropetalum flavum (Hamamelidaceae) is described and illustrated as a new species from Bat Dai Son Mountains situated in the northern Vietnam. Recently discovered plant was observed as a typical element of the rich primary forest found on the highly eroded karstic limestone mountain formations allied to the border with China. The new species is characterized by arboreous habit; stellately indumentum of branchlets, leaves and flowers; axillary, capitate, 4–12-flowered inflorescences; yellow, sessile, actinomorphic, bisexual, 4–6-merous flowers with 2-whorled perianth and 2–8 fleshy disc lobes; stamens with conspicuous subulate connective protrusion; anthers with 2 rectangular 2-sporangiate thecae, each dehiscing by 2 valves and syncarpous gynoecium with 2-locular inferior ovary bearing 2 very short separate styles. A key to all known species of Loropetalum species is given and lectotype of L. lanceum is proposed.

<em>Anthaxia</em> (<em>Haplanthaxia</em>) <em>flaviae</em> n. sp. from the Aeolian Islands (Italy, Sicily) belonging to the <em>A</em>. (<em>H</em>.) <em>olympica</em> Kiesenwetter, 1880 species-group is described, illustrated and compared with <em>A</em>. (<em>H</em>.) <em>scutellaris</em> (Gené, 1839), the most closely related species. From this latter, the new species differs mainly for size and body shape, colour pattern of elytrae, shape of antennomera, margin of anterior tibiae and shape of aedeagus. Some zoogeographical considerations concerning the insular distribution of this endemic taxon are briefly discussed.

Vriesea baturitensis is described and illustrated as a new species. It is compared with V. friburgensis and V. rodigasiana, which we consider to be morphologically the most related species. The new taxon occurs in isolated Atlantic forest patches along the Baturité mountain range, in central-north Ceará state, Northeastern Brazil. It is characterized by the compact and regular rosette, a rounded leaf apex, stiff and erect peduncle, peduncle and primary bracts bright yellow, and the particular colors and sizes of the floral bracts and sepals. The humid habitat where the new species was found, known in Brazil as brejo de altitude, is surrounded by the Caatinga (Brazilian dry woodland) and due to its climatic conditions supports a rich flora of epiphytes. In Pico Alto we collected and photographed six different species of bromeliads, two of each being Guzmania and Vriesea, one of each being Aechmea and Racinaea. We conclude that the area of Pico Alto is an important remnant of humid forest and conservation measures to protect its epiphytes are urgently needed.
