an oblong excrescence (ovule?); stigma abnormal (fig. 17). Flower 
for the rest normal. 
Eucharis amazonica Ldl (= grandiflora Pinch.). 
Habitat New Granada. 
Coll. May 1896, 1897 (Prof. Jansz). 
1°. The two diagrams show that in contrast with the normal 
flower (fig. 18) the sepals S' and S? of fig. 19 join their margins 
thus enclosing P’. The enclosed petal adheres to the tube of the 
filaments, its stamen being barren. 
2°. Synanthy. 
Hippeastrum hybridum. 
Habitat. For the majority of the species South-America. 
Coll. June 1898. 
Sepals 2, petals 2, stamens 2 + 2, ovary two-celled, stigmas 2.

The relatively great number (16) of flowers which we had an 
opportunity of examining were chiefly characterized by the 
different whorls being doubled and that by the kind in the way 
known ,collateral doubling”. From what follows it will be seen 
that the doubling affects now one whorl only, now more than 
one, and at times all of them. In order to facilitate a survey, 
we express the phenomenon in plain flower formulae and men- 
tion at the same sime the eventual peculiarities of some of the 
flowers. 
A. The formula of two specimens is: 
S; P; Sts +3 Ors, 
In this flower it is only one of the carpels that is doubled. 
In n°. 1 the fourth stigma is a little smaller than the three others. 
In n°. 2 two cells of the ovary taken together are just as 
large as each of the two others. 
B. The formula of vo specimens is: 
SP, Sigs C-., 
So here there are 5 cells in the ovary.
