Mahanty, Harekrishna (1965) A cytological study of the Scitamineae with special reference to their taxonomy. Doctoral thesis, Sir John Cass College.
The chromosome numbers have been determined for sixty species spread over all the families of Scitamineae. In about eighteen of these species, meiosis has been studied. The findings are correlated with the presumed evolution of the various groups.
The evolution of the chromosome complements in the various families is discussed in the light of the past and present cytological findings.
Further confirmation has been obtained of the conclusions reached earlier with regard to the Zingiberaceae (Mahanty 1963).
In Musaceae (broad sense) three distinct groups: (a) Musa - Ensete, (b) Heliconia and (c) Ravenala - Strelitzia - Phenakospermum are recognised and sub-familial status proposed for these.
It is suggested that haploid number 11 is the original basic number for the whole of the Scitamineae, and other numbers such as 9, 10, 11, 12, 13, 14, 16 and 17 are secondary in origin. Of these, 9 occurs exclusively or predominantly in Ensete, Costus, Canna and Orchidantha, 12 in the sub-family Zingiberoideae and 13 in Marantaceae.
