Ртлте XII. 
. Flower in bud of Agasta indica. 
. Calyx, opened, and ovary, from which the petals and stamens have fallen away. 
. One of the petals. 
. The stamens united into a monadelphous tube, which is cut open to show its form, the petals 
having been detached. 
. A longitudinal section of the calyx and ovary, showing two of its four cells, and surmounted 
by the style and disk, from the outer margin of which the staminal tube has fallen. 
А transverse section of the ovary, showing its 4 cells. 
. The fruit crowned by the persistent lobes of the calyx ; a quarter of the pericarp is cut away, to 
show the single suspended seed, marked by a groove left by pressure of the chord formed by 
the 3 abortive cells. 
. The fruit seen from below, showing its acutely quadrate form. 
. À transverse section of the mesopodal embryo, showing the line of junction of the exorhiza and 
neorhiza: all nat. size.

. The flower in bud of Agasta asiatica, with the bract at the base of the pedicel. 
. One of the four petals. 
. The monadelphous stamens combined at the base into a tube, which has fallen away from its 
attachment upon the outer margin of the disk. 
. The ovary, surmounted by the persistent lobes of the calyx, disk, and style. 
. À longitudinal section of the same, showing two of its four cells, the style, the disk with its inner 
margin expanded upwards, and its outer margin, from which the staminiferous tube has fallen. 
. А transverse section of the ovary, showing its 4 cells. 
. A fruit acutely 4-angled, the angles cordate at base upon the pedicel, surmounted by the persistent 
lobes of the calyx and the style: all nat. size. 
РтАтЕ XIII. 
A flower in bud of Butonica alba. 
2. The same after expansion. 
. The same, seen from below, showing its 4-lobed calyx, its 4 petals with retroflected margins. 
The staminal tube with the petals attached, falling away from fig. 5. 
. The pedicel, ovary, and persistent calyx of the same, the corolla and stamens having fallen off. 
. А longitudinal section of the ovary, with the persistent asina lobes, disk, and style. 
. À transverse section of the same, showing its 4 cells. 
. А diagram showing the zestivation of the petals. 
А drupe of the same, according to the dimensions given by Rumphius (it appears smaller in his 
diminished plate 115) : a quarter of the pericarp is cut away longitudinally, to show the single 
suspended seed. 
À transverse section of the embryo, showing the line of junction of the exorhiza and neorhiza: 
all nat. size. 
A portion of the raceme of Butonica racemosa, with the flower expanded. 
А flower in bud, of the same. 
One of the four petals separated (which are attached by their claws to the staminiferous tube). : 
The stamens united at base into a monadelphous tube, which is cut open, and which has fallen off 
from the external margin of the disk.
