“…Thus, diploids have been reported from tropical India (Faruqi & de Wet 1961). Tetraploids are the most common and found throughout the tropics while pentaploids and other higher polyploids are found throughout the subtropical distribution.…”

The division of north-eastern Australia into tropical and sub-tropical zones at approximately the latitude of 20 S, as suggested by the flowering phenology o/Heteropogon contortus, ii supported by studies on other perennial grasses of the native pastures. A progressive evolution away from an obligate short-day flowering response which characterizes the tropical forms of Bothriochloa bladhii, perhaps Themeda australis, and the exclusive tropical species Dicanthium tenuiculum, through a quantitative short-day response, as in the more widely distributed B. decipiens var. cloncurrensis, to the day-neutral or opportunistic and largely subtropical species of B. decipiens and D. sericeum, is suggested as a sequence of flowering strategies leading to wider adaptation into the subtropics.There is evidence from here and elsewhere that tropical forms or species of perennial grasses are grosser than their subtropical counterparts and this is coupled with their short-day flowering behaviour. The evidence suggests that B. decipiens and D. sericeum are the evolutionary products of taxa nearer to B. decipiens var. cloncurrensis and D. tenuiculum which exhibit day-length control of flowering.

“…Since H. hirta is an apomict (BROWN and EMERY 1958), the 2n = 54 chromosome type plants were derived probably through the fertilization of an unreduced female gamete with 36 chromosomes and a reduced male gamete carrying 18 chromosomes, as proposed for the Bothriochloa intermedia complex (FARUQI 1964 ). This also points out that H. hirta is a facultative apomict with both sexual and apomictic reproductions taking place simultaneously.…”

“…Genus Bothriochloa displays diploid (2n ¼ 2x ¼ 20) as well as polyploid species (2n ¼ 40, 50, 60, 120, 180) (Allred and Gould, 1983;Celarier and Harlan, 1957;De Wet, 1968;De Wet et al, 1963;Faruqi, 1964;Gould, 1956). Diploids are endemic to India and reproduce sexually .…”

“…Diploids are endemic to India and reproduce sexually . On the other hand, tetraploids have wide distribution in the Old World and are facultative or obligate apomicts (Celarier and Harlan, 1957;De Wet et al, 1963;Faruqi, 1964;Harlan and Celarier, 1961;Harlan and De Wet, 1963). Hexaploid species living in Africa, India, and Australia are obligate apomicts Harlan et al, 1964); but a few tetraploids and hexaploids living in Australia also reproduce sexually .…”
