A revision of the genus Calycularia Mitt. (Calyculiariaceae, Marchantiophyta)

Abstract

The genus Calycularia is revised worldwide. Descriptions, key for identification of species, differentiation from habitually similar species, distribution, ecology as well as illustrations and worldwide distribution map of Calycularia spp. are provided. C. crispula Mitt. is excluded from hepatic flora of Russia, Canada, Japan and Korea. РезюмеПроведена ревизия рода Calycularia. Приводятся подробные описания видов, ключ для определения видов, отличия их от внешне похожих таксонов, распространение, экология, а также рисунки и карта ареалов видов. C. crispula Mitt. исключена из флоры печеночников России, Канады, Японии и Кореи.

The genus Calycularia (Marchantiophyta) in Kerala part of the Western Ghats

“…Soc. 5(1): 122 (1861) (after Konstantinova and Mamontov 2010) Type species: Calycularia crispula Mitt. Plants large, 1.5-3 cm long and 0.5-1.2 cm wide, thallus dark greenish, strongly undulating and crispate margins, branching terminal, numerous pale brownish rhizoids restricted to midrib, apical portion of the thallus strongly recurved back to the dorsal surface, midrib rather distinct, dorsally flat or concave, ventrally convex, 8-20 cells thick abruptly tapering into unistratose margin, 30-50 cells wide.…”

“…Key to the species of Calycularia (after Konstantinova and Mamontov 2010) 1a Thallus deeply divided towards midrib on lobe-like structures. The costal region is relatively distinctly separated and more or less abruptly tapers into a 1-2 cell thick "wing".…”

“…Now the distribution of the species C. crispula extends to mountains of the tropics and subtropics and C. laxa found in the north and in the mountains of Siberia and the far east of Russia. Konstantinova and Mamontov (2010) studied more than 135 species from different herbaria and distribution of C. crispula is reduced from some areas and the distribution of C. laxa is extended. This genus was described in India from Sikkim Himalaya by Kashyap (1932) and later this species was reported from eastern parts of India (Pande and Udar 1956, Singh and Singh 2010b, Singh et al 2008 and from the Western Ghats of Tamil Nadu (Daniels et al 2014).…”

“…But there are several characters, which will confuse Calycularia with Pellia and Aneura (Konstantinova and Mamontov 2010).…”

On the occurrence ofCalycularia crispulaMitt. (Calyculariaceae) in the Western Ghats, India

“…and C. laxa Lindb. et Arnell (Konstantinova and Mamontov 2010). Calycularia crispula is predominantly a plant of upland areas in the tropics of Asia, Africa and Central America, whilst C. laxa is a species of temperate to arctic regions of the northern hemisphere from Japan to Russia, Alaska and Canada (Konstantinova and Mamontov 2010).…”
