The new species occurs in the Mathikettan Shola National Park in southern Western Ghats, Kerala, India, and it is only known from the Idukki district.

Induced cleistogamy: A strategy for reproductive assurance in Murdannia nudiflora (Commelinaceae)

Murdannia nudiflora (L.) Brenan is a day flower that is dependent on entomophilous pollination. Despite the lack of pollinator attractants and its short flower longevity, M. nudiflora shows high rates of fecundity, which lead to their rapid dispersal. In addition to monitoring the vegetative reproductive methods and the effect of select environmental parameters (atmospheric temperature, relative humidity, and precipitation rates) in M. nudiflora, we evaluated mating systems in this species via artificial crosses. This species has evolved to undergo autogamy to ensure reproductive success when pollinators are insufficient; cleistogamous flowers are produced for optimal pollinator activity when environmental conditions are unfavorable. The number of cleistogamous flowers produced was found to be positively correlated with humidity and precipitation rates, and negatively correlated with temperature. In addition, it was found that high humidity and precipitation always hinder insect pollinators. Therefore, the combination of vegetative reproduction, entomophily, and cleistogamous self-pollination helps this weedy species to propagate with maximum efficiency. Murdannia nudiflora employs pre-anthesis cleistogamy as a mating strategy for reproductive assurance while retaining mechanisms that promote out-crossing.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Sonerila longipedunculata sp. nov., a new species of Melastomataceae from the southern Western Ghats, India, with additional notes and lectotypification of Sonerila travancorica

A new species of Melastomataceae, Sonerila longipedunculata Resmi & Nampy sp. nov., is described from the southern Western Ghats, India. It is morphologically close to S. travancorica, but differs by the tuberous root stock, fleshy stems, ovate to cordate lamina, longer, angular peduncles, 3-ribbed hypanthium, ovate-elliptic petals, acute anthers, and 3-ribbed capsules. Detailed description, distribution map, and photographic images are provided. The morphological differences with relevant species are discussed. The status of the new species is provisionally assessed here as ‘critically endangered’ according to IUCN Red List Categories and Criteria. The name Sonerila travancorica is lectotypified and its identity is discussed. The status of Sonerila longipetiolata is discussed and is synonymised under S. travancorica
