The pedicel usually contains from five to eight cords arranged 
in a circle (1). They then begin to spread out and become fan- 
shaped (2), multiplying by lateral chorisis, until a complete circle 
is seen in section (3). This gives off three or four branches to 
each sepal. The ring continues to increase by radial chorisis 
and small cords are thrown off for the stamens, each issuing from 
a sort of bulbous base (4 and 4 a). Figures 5 and 6 represent 
two sections near the apex of the floral receptacle cutting through 
the carpellary cords. Of these there are but few, sometimes only 
five are left (6), thus revealing their phyllotactical origin. As 
soon as the carpellary region is reached, the branches increase in 
thickness in a marked manner (7, 8) before sending off slender 
cords to the carpels. This curious augmentation is well seen in 
radial and tangential sections (7, 8). The cord on reaching the 
base of the carpel divides, sending off one branch to the apex of 
the style, the other ascends the margin of the carpellary leaf and 
supplies the single pendulous ovule with its cord (9). 
II. ANEMONE CORONARIA.—The peduncle about an inch below 
the involuere agrees closely in its anatomical structure with that 
of Narcissus, Ornithogalum, &c., for it contains two somewhat 
irregular circles of cords around a lacuna (1), those of the inner 
circle being considerably the larger. On approaching the invo- 
luere the cords increase in number and unite in various ways. 
Figure 2 represents three cases. The branches sent off to the 
circumference enter and ramify within the three leaves of the 
involucre. After having done this, the axial cords first resume 
their former arrangement, as in fig. 1; they then form a single 
circle, by the smaller cords becoming intercalated between the 
larger of the previously more central ring. Each sepal now 
receives its supply of cords and the ring closes up again, increases 
by chorisis, and behaves as in Clematis. 
II. RANUNCULUS FLAMMULA.—In the flower of this species, 
which is somewhat degraded, I found in one instance, but did not 
succeed in repeating the observation, that tho papille of the
