On one stem both leaves of a pair were two-topped. 



Wldtfieldia latei'itia 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 out. 



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. 



VERBENACEAE. 



Tectona Hartiiltoniana Wall. 



Habitat Farther India, Philippine Islands. 



Coll. Nov. 1895. 



NJ3. 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'/2 cM. 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 iu 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 in 

 normal cases. 



Lantana Camara L. 



Habitat America, having run wild in the East Indies. 



Coll. December 1894. 



NB. The leaves are normally in pairs at right angles.
