The Javanese draughtsman IN atadipoera whose technical accu- 

 racy is well known has produced a great many representa- 

 tions which cannot but excite great admiration and should all 

 have been reproduced both for giving an idea of the variabi- 

 lity of the Tectona-leaf and ft'om an artistic point of view. 



I shall, however, confine myself to a few of them. (fig. 17 

 and 18). 



A few remarks may be added: 



The leaves which have been drawn and descril^ed are all 

 taken from plants reared in the nursery-gardens from seeds. 

 Mr. Ham, inspector of the Forestry was so obliging as to dis- 

 patch them to Buitenzorg. 



A similar material lias reached Dr. Smith through the kind- 

 ness of Mr. Salverda, chief inspector of Forestry. It came 

 from a tree of 20 years and is especially remarkable because, 

 according to the observations of Mr. Salverda and others, a 

 tree once having commenced to produce such deviations never 

 ceases to produce them. The question arises if this aberration 

 may be multiplied by means of seed, a question apparently 

 not difficult to solve, and which we have submitted to Mr. 

 Salverda's notice '). 



h. coll. C. Brandts Buys, applicant forester, Bodja, 1909. 



We owe another remarkable case of deviation to Mr. Brandts 

 Buys, forester and charged with the culture of Teak-forest at 

 Kennetep, Larangan, Kendal. It has again been Mr. Salverda 

 who suggested its being forwarded to Buitenzorg. 



Dr. Smith had the happy thought to send me the whole 

 material consisting of a tree of less than one year, but already 

 in full bloom. Its height amounted to 1.43 M. 



The lowest 8 pairs had fallen, on the 5th and 6th nodes 

 there were branchlets. 



The 9th pair show^ed normal size. 



1) That a Tectona-tree which produces abnormal leaves may be backward also in 

 other respects, is apparent from an information of Mr. ten Oever's: the specimen, 

 which produced the abnormal mateiial, is three years old and has a height of 2.8 

 M. instead of 6.75 being the standard at that age.
