- W2473762185 abstract "Summary. Arisaema muricaudatum, a new species of Araceae from South India is described. The genus Arisaema includes more than 200 species in fifteen sections distributed in Eastern Asia-the centre of distribution, Africa (Ethiopia), Eastern North America and Central America (Mexico). Members of the genus are mostly represented by dioecious taxa, sometimes monoecious with a bisexual spadix. Sexuality depends on the nutritional conditions and pistillate spadices usually are produced from larger corms and staminate-flowered spadices from smaller corms. Nakai (1936) proposed the term 'paradioicus' for such variable sexuality. As in most members of the family, species of Arisaema exhibit a great range of plasticity in all their features. During a detailed survey of aroids of South India, a new species that differs from all the species mentioned by Engler (1920) and later workers including Chatterjee (1959) was discovered. Arisaema muricaudatum Sivadasan sp. nov. Species proxima A. filiformi (Reinw.) Bl., sed cormis instructa, foliolis sessilibus, et limbo spathae ad basim non auriculo differt. Typus: Kerala, Malappuram Dist., Nilambur Ghats, Thalichola, c. 700 m, 10 April 1981, Philip Mathew CU 28426 (holotypus K). Cormous herbs; corms 2-5-3-5 cm diam., 1-5-3 cm thick. Leaf solitary; petiole 30-85 cm long, 7-10 mm diam. at the base, tapering to c. 4-6 mm at the tip, green to greenish with light greenish or rarely purplish mottling, sheathing to more than three-fourths the length; blade subpedate with 5-7 leaflets each 13-15 x 3-5 cm, obovate to oblong acuminate. Cataphylls 3-4, varying in length to 36 cm long, slightly narrowed to tip, tip acute with a recurved mucro. Inflorescence with penduncle 43-62 cm long, base 8-10 mm in diam., apex 3-5 mm diam.; spathe 13-19-5 cm long with a basal convolute portion 4-5-6 cm long and 1-25-1-75 cm diam., and an upper expanded, ovate to lanceolate-acuminate limb portion 8-13-5 cm long; the basal portion green and the upper limb portion greenish with purplish tinge or light purplish; spadix usually bisexual, sometimes unisexual and then usually staminate, sessile, 22-34-5 cm long, bisexual spadix differentiated into a basal pistillate portion c. 1-3 cm long, an intermediate staminate portion c. 1-5-2 cm long, sometimes followed by neuter flowers, and an apical long-caudate appendix. Pistillate flowers numerous, loosely arranged, ovary green, ovoid, with 4-5 basal orthotropous ovules; style short, stout, conical; stigma capitate, subpapillose. Staminate flowers represented by many scattered groups of 4-6 ovate anthers borne on a short stalk, usually purplish or whitish-creamy, sometimes stalk creamy in colour and anther lobes purplish; dehiscence by" @default.
