Two Petrified Palm woods from the Deccan Intertrappean Beds of Mandla District, Madhya Pradesh

Abstract

The present paper deals with the anatomy of two new species of Palmoxylon, P. parapaniensis and P. mandlaensis, collected from the Deccan Intertrappean beds of Parapani and Mohgaon in Mandla District, Madhya Pradesh. Palmoxylon parapaniensis shows a prominent lacunar ground tissue throughout the wood and belongs to Cocos-like forms, whereas the ground tissue is compact in P. mandlaensis; this belongs to Corypha- like forms.

Sabalocaulon intertrappeum gen. et sp. nov. from the Deccan Intertrappean beds of Madhya Pradesh, India

“…It is also noteworthy that the fosstl appears to have affinities with Palmoxylon parapaniensis described from the same locality by Lakhanpal et al (1979). The palm wood and the fossil described here share some characters as the structure of fibrous bundles leaf trace bundles, diminutive fibrovas~ular bundles and lacunar ground tissue.…”

“…Therefore, the fossil wo.od described by Lakhanpal et al (1979) mIght also belong to Sabaloid Group of palms.…”

“…The ffi1.terial was collected from the Deccan Intertrapp~an beds of Madhya Pradesh exposed at Parapani, a village in Mandla District. So far, only two palm woods, viz., Palmoxylon parapaniensis from Parapani and P. mandlaensis from Mohgaon have been described from this district by Lakhanpal et al (1979).…”

Palmoxylon siltherensis sp. nov. from the Deccan Intertrappean beds of Mandala District, Madhya Pradesh

“…Palmoxylon species with compact ground tissue comparable with the present fossil species are: Palmoxylon sahnii Rode (1933), P. scleroderrnum Sahni (1931Sahni ( , 1964, Shukla (1946), P. surangei Lakhanpal (1955, P. rewahense Sahni (1964), P. liebigianum Sahni (1964), P. coronatum Sahni (1964), P. compactum Sahni (1964, P. maheshwarii Rao & Menon (1963), P. raoi Menon (1968), P. puratanum Ramanujam (1958), P. mohgaonensis Trivedi & Surange (1970), P. splendidum Trivedi & Chandra (1971), and P. mandlaensis Lakhanpal et al (1979) but the present fossil species is closely comparable only with Palmoxylon sc1erodermum.…”

On some plant remains from Deccan Intertrappean localities of Seoni and Mandla districts of Madhya Pradesh, India

“…Lakhanpal et al 1979, P. pondicherriense Sahni 1964 and P. sundaram Sahni 1964 fall under this category. In the first three species and in the dermal part of the fourth species fibre bundles are absent and hence differ from the present fossil.…”
