1901] ZION OF RED COLOR 335 
shown on one side of an upright stem than on another were 
found to be where light was brighter on the red side. 
In creeping stems and inclined branches there was more red 
on the upper surface in 12 cases (5.7 per cent.), and on the 
lower surface in one case (1 per cent.). 
Of 140 petioles more red was shown on the upper surface in 
53 cases (38 per cent.), evenly distributed in 46 (32.8 per cent.), 
near the base in 39 (28 per cent.), on the lower surface in 10 
(7.1 per cent.), near the blade in 5 (3.5 per cent.). In peti- 
oles, therefore, red color is most frequent on the upper sur- 
face, but nearly as often evenly distributed, while some petioles 
show a tendency to color toward the base. 
Of 65 veims more red was. shown evenly distributed in 32 
Cases (49.2 per cent.), on the upper surface in 18 (27.7 per 
cent.), on the lower surface in 15 (23.1 per cent.). It follows, 
therefore, that in veins, as in stems, the red color is evenly dis- 
tributed in the majority of cases, and that there is more color 
on the upper than on the lower surface. 
Of 99 deaves (mesophyll) more color was shown evenly dis- 
tributed in 33 cases (33.3 per cent.), on edge in 20 (20.2 per 
cent.), on upper surface in 18 (18.1 per cent.), at tip (mostly 
young) in 15 (15.1 per cent.), on lower surface in 14 (14.1 per 
cent.), at base near petiole in 11 (11.1 per cent.). The conclu- 
sions, therefore, are that cases of even distribution are in the 
Majority ; that there is more color on the upper than on the 
lower surface, and on the edge than near the tip. 
In a large number of cases the red color was seen on flower 
stems, bracts, and scales, but because these could not be ascer- 
tained for all plants the results were not tabulated. Buds, 
Stipules, spines, tendrils, and a few roots were also found col- 
ored red. Out of the 285 specimens 26 were streaked or mot- 
tled in some way. 
The next records consider the color distribution in relation 
to external conditions, as light,etc. Of the 285 plants examined 
150 (52.6 per cent.) were gathered in dry sunny places, 61 
(21.4 per cent.) in dry shady places, 4o (14 per cent.) in wet
