early days of August many branches were still growing. Later 
in the year some branches were found terminated by scars, but 
these seemed to be caused by the breaking off of the fruited 
flower clusters at the ends of the branches. Lonicera flava (Fig. 
22) has the tips withering away, but not falling off at a well 
marked scar. The dried up tips may be seen between the upper 
pair of leaf buds. 
Cephalanthus occidentalis has its branches almost invariably ter- 
minated by inflorescences, a part of which have never developed ° 
into flowers. The few tips with flower buds show shriveled-up 
leaves at the ends of stems, drying back a little, thus giving rise 
to sympodial growth. 
Catalpa speciosa, Warder, was figured (Figs. 1, 2) on Plate 
CXXXIL. of this journal. During the early days of August most 
of the tips had been cast off; here and there the very short, 
shriveled remains embracing only a few nodes were still attached 
to the stem. The tips of a few of the lower branches were grow- 
ing vigorously and did not lose their tips until later during the 
month. It was impossible to get satisfactory specimens from 7Ze- 
coma radicans. Many branches were still growing when exam- 
ined. Where there were terminal scars it was often possible to 
ascribe these to the falling of the flower clusters, where fruiting 
had not set in. One case was found where apparently the leafy 
tips of a branch had fallen off, but the case was not altogether sat- 
isfactory. 
Diospyros Virginiana, with its shriveled-up tip, was figured 
(Fig. 9) on Plate CXXXII. of this journal. Terminal scars are 
also common. 
Ulmus Americana (Fig. 10 and Fig. 8 of Plate CXXXII. of 
this journal) and Ulmus fulva (Fig. 8) both lose the tips of their 
branches, indeed, quite early in the year. Ulmus campestris was 
observed at Heidelberg, Germany, to have lost about one-third of 
its tips during the last week of May, although the future plane of 
separation was becoming visible in the remainder. Celts occt- 
dentalis (Fig. 11) also shows the terminal scar. A little feature 
was noted which will well serve to readily distinguish this tree in 
winter time, when other aids are not at hand. The scaly bud in 
the axil of the last remaining leaf is quite strongly bent away from
