ABSTRACT Lactuca pygmaea Bhellum (Asteraceae, section scariola F. W. Schmit) – a new species from India is
described and illustrated. It grows gregariously on open and dry places. The field survey was made in the surroundings of Jammu in 2014 and specimens were studied with the help floristic literature. The area of the entire State of Jammu and Kashmir of India lies between 32° 17´ – 36° 58´ N and 73° 26´ – 80° 30´. The new species differs from its closely relative related Lactuca dissecta L. in its height being short, leaves entire or remotely lobed, size of phyllaries capitula, pappus, and achenes. Therefore, it represents distinct species of Lactuca L. genus. .

I have updated eFI (efloraofindia) page on Lactuca (Pl. click). Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links. Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details. If someone can provide complete list of Indian species with source references it will be wonderful. . Fwd: Lactuca images : 1 post by 1 author.

Pl. go through Lactuca (Asteraceae (Compositae)) page with images of species (done by …) in efloraofindia. If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice. . Flora Simlensis and Flora of Muscsoorie describe only two species as per following Key
1. leaves ovate or triangular, not variable, heads few, solitary or subsolitary, on long stalks: P. violaefolia
2. leaves variable, heads many in terminal panicles: P brunoniana
from Flora Simlensis
