130 WILD AND CULTIVATED COTTONS 



South other cottons derived from G. obtusifolium. The writer has on his 

 cottons. table at the present moment an extensive series of forms, all of 

 which he regards as belonging to this position. Thus, for example, 

 on the extreme left hand he has placed the roji cotton of Gujarat as 

 the form of yellow-flowered perennial cotton which, in foliage and 

 other structural peculiarities, approaches nearest to G. arboreum of 

 any of the G. Nanking group. Next the yerra patti or errapathi 

 chettu of Kistna and Karnool (nn. 131 and b. 1 and 4) a plant which 

 does not appear to attain to a greater stature than three feet, and 

 which in many respects resembles var. sanguined but with yellow 

 flowers and triglandular midribs, thus coming close to the bani 

 cottons of the Deccan. Errapathi chettu is a profusely flowering 

 plant with the leaves much smaller than in ordinary nadam, and in 

 which the tertiary branches, instead of producing one or at most two 

 flowers (as in G. arboreum), are elongated and bear three to six flowers, 

 so that the plant becomes pyramidal. Flowers are yellow but with 

 purplish tinge, and the cotton large, coarse, and dirty white. Next, 

 the nadam parthi chedi of Coimbatore (n. c. 22) and also other ex- 

 amples of the same from Coimbatore (nn. c. 4 and 19). All these are 

 found on sandy or red soils, but those that may now be given are 

 said to be grown on black soils and approach very closely to the 

 condition met with in G. obtusifolium. They are karung kanni 

 parthi chedi of Tinnevelly (nn. d. 1, 8, 11 and 14) ; and the villa 

 kanni parthi chedi of that district (n. d. 4). Both these are said to 

 be grown as mixed crops, but to attain a height of only 2-3 feet. 

 The remaining forms of nadam, that might be mentioned, partake 

 far more of the uppam or rekkam characteristics, and indeed 

 appear to have been collected from fields of that plant, and are 

 apparently sports or natural hybrids. So also many of the forms 

 of errapathi chettu (above mentioned) come remarkably close to 

 the roji. 



I adopt the name nadam (or yerra) because it is that ascribed by 

 the Natives of India to one of the most extensively cultivated repre- 

 sentatives of the present series of cottons the nadam (or paira or 

 burada) cottons of South India. Professor Middleton speaks of it as 

 the roji of Madras, but he might also have added ' or the bani of 

 Central and Northern India.' In fact the separation of the varieties 

 or races of G. Nanking is exceedingly difficult, and the names I have 

 suggested should perhaps be accepted as indicating geographical and 

 agricultural rather than botanical forms. There is, however, a
