Studies in the Glossopteris Flora of India - 24. On two new species of fossil wood from the Raniganj stage of Raniganj Coalfield, Bengal

Abstract

This paper contains a description of two new species of the genus Dadoxylon Endl. D. jamuriense sp. nov. is characterized by a homogeneous pith, endarch primary xylem, 1-45 cells deep xylem rays and multiseriate radial pits. D. ningahense sp. nov. is characterized by multiseriate radial pits and 1-2 seriate tangential pits.

Coniferous Fossil Woods from the Jogyeri Formation (Upper Triassic) of the Nampo Group, Korea

“…Our specimens have 1-3 rows (usually 2 or 3 rows) of pits on the radial tracheid walls, 3-6 araucarioid pits per cross-field, and rays that are 1-15 (usually 6-10) cells high. Twenty-four species of Araucarioxylon (or Dadoxylon) which have 1-3 rows of pits on the radial tracheid walls have been reported (Shimakura 1936;Ogura 1944;Surange & Sah 1956;Veillet-Bartoszewska 1956;Kräusel & Jain 1963;Sah & Jain 1963;Maheshwari 1963Maheshwari , 1964Maithy 1964;Vogellehner 1965;Boureau & Koeniguer 1966;Lemoigne & Demarcq 1967;Japiassu 1970;Desplats 1976;Prasad 1982;Roselt 1986;Giraud 1991;Nishida et al 1993). Among them seven species have usually 3-6 pits per cross-field (D. duartei, D.…”

Two new species, Araucarioxylon Surangei and A. lathiense of petrified woods from Lower Gondwana strata

“…This work was further intensified by Agashe and Gowda (1978) who studied the petrified woods from the different Lower Gondwana localities in Maharashtra State. In India, a number of workers like Holden (1917), Surange and Maithy (1961, 1962, 1963, Maheshwari (1965), Maithy (1965Maithy ( , 1967Maithy ( 1974, Kulkarni (1969), Kulkarni, Maithy and Surange (1969), Agashe and Chitnis (1971), Lakhanpal et al (1975) and Agashe and Gowda (1978~have r~ported quite a number of petrified fosstl woods from the different localities.…”
