Whitfieldia lateritia Hook. 
Habitat Tropical Africa. 
Coll. February 1895. 
Four abnormal flowers. Of all the calyx is dialytic, the sepals 
cohering only at the base. They differ amongst them in 
length and width, but are for the greater number oblong- 
lanceolate. One or two of them are threadlike. Their number 
oscillates between 6 and 7. 
Also the corolla shows augmentation, viz. in three cases 7, 
in the fourth 6. In the latter case the upper and underlip 
are still easily distinguishable, in the other ones the limit is 
scarcely to be pointed ont. 
The fertile stamens are present in the number of 6, in one 
of the flowers only a sterile one has been added to them. 
The pistil is normal in the four flowers, so are the bracts. 
VERBEN ACEAE. 
Tectona Hamiltoniana Wall. 
Habitat Farther India, Philippine Islands. 
Coll. Nov. 1895. 
NB. In normal plants the leaves are in whorls of three. 
In a shoot springing from the base of the stem the lower 
leaves were alternate, then followed, 7 '/, eM. further on, two 
leaves nearly opposite. In this place the branch broadens 
gradually and shows on the broad side a groove. 5'/, cM. 
higher up four leaves are found almost in a whorl and just 
above it the shoot bifurcates into one with four-whorled 
leaves and one with alternate leaves, followed by a pair of 
opposite ones and finally producing whorls of three as iD 
normal cases.
