Spiderwort (Commelinaceae)

Spiderwort (Commelinaceae) is a family of plants in the Commelinales, flowering with about 731 species in 41 genera, have morphological variations, especially inflorescences which are very high among angiosperms, well-developed stems and often swollen at the internodes, short-lived flowers and widely cultivated as ornamental plants.

Commelinaceae usually perennials but a small number of species are annuals, terrestrial except for plants in the genus Cochliostema which are epiphytes. Upright and often spreading by rooting on internodes or stolons. Some have rhizomes and climbers. Roots are fibrous or tuber-shaped.

The leaves form a midrib at the base and surround the stem. The leaves are alternate on the stem and may be two-tiered or spirally arranged. The leaf blades are simple and intact, sometimes narrowing at the base and often watery.

Inflorescences on the terminal shoots on the top of the plant or on the terminal shoots and axillary of the lower internodes. Flowers are usually all bisexual, but some species are andromonoecious, gynomonoecious and polygamomonoecious.

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

Perlis fairy lantern (Thismia perlisensis) resembling Thismia arachnites Ridley and Thismia javanica J.J.Sm.

NEWS - Perlis fairy lantern ( Thismia perlisensis Besi & Rusea sp. nov.) was discovered during a scientific expedition in a wetland forest at the foot of a limestone hill, Perlis State Park, resembling Thismia arachnites Ridley (1905) and Thismia javanica J.J.Sm. (1910), but has a prominent reddish dome-shaped annulus. Thismia perlisensis can be easily distinguished from T. arachnites and T. javanica by its blood-red dome-shaped annulus (vs. ring-like with a rim, orange annulus), prominent trilobed stigma with bifid and subulate lobes 1.8 mm long (vs. oblong, truncated stigma), and claviform apex of inner tepal appendage (vs. subulate apex of inner tepal appendage). Stenoendemic to northern Peninsular Malaysia, Perlis State and possibly Langkawi Island. Although there have been sightings of the plant on Langkawi Island, this location is based solely on photos posted on social media. There are currently no specimens or additional information to confirm. The new species grows in...
