lobed leaves, yellow flowers and a large calyx, which is about the 

 same length as the fruit, from 5-7 seeds in each chamber, the long 

 seed-hairs are 2-2, 8 cm. long. 



//. Gossypium hirsutum. L. (Upland cotton) with strongly 

 haired leaves and flower stems, 3-5 lobed leaves, where the lobes 

 reach about half way down the leaves, smooth fruits and from 6-8 

 seeds in each chamber. The long hairs have an average length of 

 2-5 cm. This kind is of greatest importance for America. The 

 produce of cotton in America consists chiefly of this kind. 



B. Only seed hairs and no felt-like covering over the seeds. 



III . Gossypium barbadense. Z. (Sea-island cotton, the best kind 

 of cotton) with 3-5 lobed leaves yellow flowers, and 6 loose seeds 

 in each chamber. Seed hairs to 5 c.m. long. 



IV. Gossypium peruvianuvi. Cav. (Syn : G: religiosum. Pit.) 

 South American cotton up to 5 m. high with big from 3-5 lobed 

 leaves white flowers and from 5-10 seeds in each cavity which are 

 connected with each other. Seed hairs up to 3-5 cm. long. 



All these Gossypium kinds are over-one-year plants but G. her- 

 baceum is the only annual plant, outside tropical zones. 

 G : arboreum. L. which will be mentioned later reaches a height 

 of from 5-7 m. As a culture plant this kind has not been much used. 



i\ccording to TEYSMANN, there are three kinds of cott »n in Java 

 of which many varieties are known. 



He divides the cotton into yearly and shrubby or limited- 

 growth cotton varieties. 1 his classification is more of an artificial 

 nature and rests more on a practical than a scientific foundation 

 as, as is already mentioned above, all kinds of cotton with the 

 exception of G. kerbaeeum, grown outside tropical "countries, may 

 be considered as plants of limited growth. But, in fact in prac- 

 tice only perennial kinds are reared as annuals- 



To the annual kinds to be found here, TEYSMANN reckons : — 



I. G. indicum. Lam , G. Jierbaceitm. L., one and the same 



species. 



II. G. religlosum. Svv. 



III. G. barbadense. L. 



and to the shrub-like kind or limited-growth cotton kinds, the 

 following pair: — 



IV. G. vitifolium. Rxb. 

 V. G. mieranthum. Cav. 



According to later systems, G. religiosum and G. vitifolium 

 should be varieties belonging to G. barbadense and G. mie rant hum 

 belonging to G. kerbaeeum or indicum. 



As in some other plants which have been cultivated for a consi- 

 derable time it is also the case with cotton that the systematic 

 varieties and kinds are difficult to determine. 



However it may be from TEYSMANN'S investigations, it is clearly 

 >eeu that in our archipelago besides the inferior also the best kinds 

 are cultivated. 



The best varieties are those which come under the species G. 



barbadense.- 



TEYSMANN considers as^ belonging to G. indicum or kerbaeeum —
