The lectotypification of Syzygium occidentale (Bourd.) Gandhi (Myrataceae)
S.M. Shareef *
*Corresponding author. E-mail: smshariftbgri@gmail.com
Based on two collections from the banks of the Periyaur (=Periyar) River in North Travancore, Bourdillon (1904) described and illustrated Eugenia occidentalis Bourd (Myrtaceae). Gamble (1919) transferred it to Jambosa, as J. occidentale (Bourd.) Gamble. Gandhi (1976) later proposed Syzygium occidentale (Bourd.) Gandhi. Neither Bourdillon nor subsequent authors designate a lectotype from among the two syntypes preserved at K nor did any author declare the published figure as the lectotype. Among the syntypes, K!, barcode no. 000793886, was used by Bourdillon for the diagnosis and illustration of E. occidentalis and hence this specimen is here designated as the lectotype.

Leptolejeunea epiphylla (Lejeuneaceae): An addition to the Western Ghats
K.C. Kariyappa & A.E.D. Daniels*
*Corresponding author. E-mail: dulipdaniels@yahoo.co.uk
During a bryophyte survey, Leptolejeunea epiphylla was collected at Mundanthurai and Palode in the Western Ghats, India. In both localities it was found to inhabit the leaves of Arenga wightii Griff., an endemic, understorey palm, commonly seen in evergreen and riparian forests of the southern Western Ghats. This record is an addition to the liverwort flora (especially to the epiphyllous flora) of the Indian mainland because in India, this species was so far known only from the Andaman and Nicobar Islands. It is one among the 11 species of Leptolejeunea (Spruce) Schiffn so far known to occur in India . The species is briefly described and illustrated, and its distribution is mapped.

Taxonomic status of Pavetta bourdillonii (Rubiaceae)
E.S.S. Kumar* & N. Mohanan
*Corresponding author. E-mail: santhoshkumares@gmail.com
The genus Pavetta L. has about 300 species distributed in the paleotropical regions of the world. Bremekamp (1934) laboriously studied this genus in details but his narrow species concept resulted in the recognition of many more species than can be justified taxonomically. He recognized 42 species for the Indian subcontinent, while Rout and Deb (1999) accepted only 25 species. Most of the characters used by Bremekamp to delimiting species, such as stem characters (green vs corky), shape and size of leaves, and arrangements of bacterial nodules in the leaves, were rejected by Rout and Deb. However, the position of the inflorescence (axillary vs. terminal) was found to be useful taxonomically by both parties.

The lectotypification of Syzygium bourdillonii (Gamble) Rathakr. & N.C. Nair (Myrtaceae)
S.M. Shareef
*Corresponding author. E-mail: smshariftbgri@gmail.com
Based on two collections of Thomas Fulton Bourdillon (1849–1930) (nos. 596 & 859), made during 1895 on the Merchiston estate in the erstwhile Travancore State, James Sykes Gamble (1847–1925) erected a new species, Jambosa bourdillonii Gamble, in 1918. Rathakrishnan & Nair (1983) later proposed the combination, Syzygium bourdillonii. There was no other collection made until the rediscovery of the species from Agasthyamala of the Kerala region after 94 years. Subsequently, Murugan & Manickam (2006) recorded its occurrence in Tamil Nadu. Neither Gamble nor any subsequent authors designated a lectotype from the two known syntypes preserved in K (T.F. Bourdillon 596 & 859) and MH (T.F. Bourdillon 596). The Kew sheet of 596 (K000793900!) is designated here as lectotype and the duplicate at MH as an isolectotype.

Rediscovery of two Pyxine (Physciaceae) species from the Western Ghats
H. Biju*, R.G. Bagool & S. Nayaka
*Corresponding author. E-mail: drbijutbgri@gmail.com
The lichen genus Pyxine was established by Elias Fries in 1825 and it is a prominent member of the family Physciaceae. The genus Pyxine is mainly pantropical to subtropical with several species extending into temperate or oceanic regions, and comprises ca. 65 species. Index Fungorum (www.indexfungorum.org) holds a total of 162 records for Pyxine, which include 96 species and several infra-specific taxa. However, many taxa in that list need validation (e.g., P. consocians Vain. is mentioned as synonym of P. subcinerea Stirt.). In India, the genus harbors about 26 species, of which 10 are recorded for Kerala. Pyxine is characterized by dorsiventral, appressed, foliose thalli with linear radiating lobes, anatomically heteromerous, paraplectenchymatous upper cortex, white or yellow medulla, fibrous lower cortex, laminal apothecia with thalline or pseudothalline margin, epithecium K+ violet-purple, dark brown hypothecium, generally two-celled, mischoblastiomorphic brown spores, and simple paraphyses.
