456 GOURLEY: FRUIT BUD FORMATION 
plates which he shows are illustrations of true axillary flower buds 
and not spurs as indicated in his text. 
Practically the same statement is found in Technical Bulletin 
No. 10, New Hampshire Experiment Station, by Miss C. A.

Black, which adds to the importance of 
having the matter corrected. In the 
latter article the author states that “‘the 
few scars at the base of this inflores- 
cence indicate that it is really terminal 
and not axillary.’”” This would indicate 
that proper material was not at hand 
for examination, for where axillary flower 
buds are formed it is impossible to see 
more than the one large leaf scar and 
there is no possible point of attachment 
for other leaves to be found. Her state- 
ment that “such buds are few in num- 
ber and of no vigorous growth” is also 
an error, although they often do ‘“‘de- 
velop later than the usual terminal flow- 
er buds.” A wrong interpretation is 
furthermore given of pl. 33, f. 2, of this 
bulletin. I would consider this figure to 
represent a two-year-old shoot and not a 
three-year-old one, for it is common to 
find a shoot develop from the flower 
cluster and develop as shown in this 
figure. In fact two such shoots often 
are found on the spur with an apple 
developing also. 
In observing wild species of Pyrus and Malus at the Arnold 
Arboretum I have found the following list to form fruit buds in the 
axils of the leaves rather profusely: 
Malus pumila Niedzwetzkyana M. baccata mandshurica Schneid. 
Schneid. 
M. baccata sanguinea Hort. 
M. pumila apetala Schneid. M. baccata aurantiaca Hort.
