box and pot A, but none soi far between pots A and B. The color 

 of the foliage from pot F on is a rich dark green. 



Main Stem. — ^Before August 16tli, the M. S. had maintained 

 a uniform rate of four inches a day, for twenty days. On August 

 16th, the rate dropped to two inches in one day, and continued 

 to drop more or less evenly until it stopiped on August 31st. 



The first opposite leaves had appeared on July 25th on the node 

 rooted in pot 3 on July 27th. After that the stem gradually be- 

 came fasciated. On August 15th it was already half an inch wide. 

 On August 31st the tipi, having grown only about eighteen inches 

 since passing pot 6, Avas rooted in pot 7. The then very broad tip 

 curved around, cracked, and resolved itself into several branches, 

 as described under "Main Branch," with the difference that none 

 of the resulting branches assumed a rapid rate of growth, so that 

 now (October 25th) the longest branch measures scarcely ten 

 inches. The total groiAvth of all branches, given in Eig. 2, as "Main 

 Stem Rosette," does not amount tO' one-half inch per day. 



All leaves on the main stem have gradually become lighter in 

 color since August 16th, except those in pot 7, which are normal, 

 although not as dark as those in pots E, G, H, &c. 



Between the box and pot 2, and half-way between pots 2 and 3, 

 all leaves have now dropped. 



Of all small branches started all along the stem between the box 

 and pot 5, not one has increased in length since August 16th. The 

 longest, near the box, were at that time six inches long. At present 

 all small branches from the box up to betAveen pots 3 and 4, i. e., 

 between two watered pots, have dried back from the tip, the basal 

 ones most. 



Side Branch 3.- — Before August 16th, S. B. 3 was growing at 

 an average rate of three inches, keeping pace Avith S. B. 1 and 2. 

 On August 14th it had been potted in pot 6, but had, of course, 

 not yet rooted well. Erom August 16th until August 21st the tip 

 stood still and turned yellow, and the four basal leaf axils sent 

 out shoots. On September 5th the most distal shoot had a, length 

 of six inches, the next four, the third two, and the basal had just 

 started. After September 5th, the proximal shocft assumed the 

 greatest rate of groAvth, and the apical the least, so that on Sep- 

 tember 19th the lengths of the four shoots Avere: basal, 15 inches; 

 next, 12 inches; next, 4 inches, and apicah, 6 inches.
