Impatiens theuerkaufiana, a new scapigerous species of Impatiens (Balsaminaceae) from Wayanad district, Kerala, India is described and illustrated. It differs from I. dendricola by having entire lateral sepals, a transversely elliptic, bilobed dorsal petal with wavy margins, a short straight spur less than 5 mm long, and tuberculate seeds; from I. agumbeana by having pendulous linear lanceolate leaves, shorter pedicels up to 3.5 cm long, non-auricled lateral united petals, and an ellipsoid capsule; and from I. stocksii by having long petioles of 5-8 cm, an elliptic lanceolate leaf lamina, long pedicels of 2.0-3.5 cm, and a pouch-like short spur.
Sonerila veldkampiana, a new species of Melastomataceae collected from an exposed, high-elevation rocky grassland in Kerala, India is described and illustrated. It resembles S. rotundifolia, but differs in having several important characters like pilose leaf-lamina, terete and glabrous peduncle, inflorescence with 10–35 flowers in branched or unbranched scorpioid cymes, an obscurely ridged hypanthium, long acuminate anthers with a deeply cordate base, and seeds with a sub-excurrent raphe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
