American flora. For instance, in Gray’s New manual of botany? 
the staminate flower of the Juglandaceae is said to have “an 
irregular calyx adnate to the bract,” and the pistillate flower to 
have ‘‘a regular 3—5-lobed calyx adherent to the ovary.” Further- 
more, under Carya the staminate flower is simply described as 
“stamens 3-10; filaments short or none, free,’’ while ‘‘a. four- 
toothed calyx; petals none” is attributed to the pistillate flower. 
SARGENT® describes the staminate flower of Carya as follows: 
“Calyx usually 2-, rarely 3-lobed, subtended by an ovate acute 
elongated bract free nearly to the base, and usually longer than 
the ovate rounded calyx-lobes.”” In the pistillate flower the calyx 
is said to be ‘‘reduced to a single posterior lobe,” and the ovary to 
be ‘‘inclosed in a perianth-like slightly 4-ridged involucre, composed 
by the more or less complete union of an anterior bract and 2 
lateral bractlets, adnate below to the ovary, unequally 4-lobed at 
the apex.” 
Britton‘ describes the staminate flower of Juglandales as 
‘‘consisting of 3-numerous stamens with or without an irregularly 
lobed perianth adnate to the bractlet,” and the pistillate “‘bracted 
and usually 2-bracteolate with a 3-5-lobed (normally 4-lobed) 
calyx or with both calyx and petals.”” Under Hicoria the staminate 
flower is said to possess “‘a calyx adnate to the bract, 2-3-lobed or 
2-3-cleft,” and the pistillate flower is described as ‘‘bract fugacious 
or none; calyx 4-toothed; petals none.” This same description 
is reprinted in the second edition of Brrrron and Brown’s [/lus- 
trated flora. 
By SMALL the staminate flower of the Juglandales is said to 
possess “‘a 2~6-lobed calyx bearing several rows of stamens, or the 
calyx obsolete,” while the pistillate flower is described as ‘‘consist- 
ing of an involucrate incompletely 2-4-celled gynaecium: calyx 
partially adnate to the gynaecium.”’ Under Hicoria the staminate
