TRIDACEAE. 
Pardanthus sinensis Ker. Gawl. (= Belamcanda unctata 
Moench.). 
Habitat: China and Japan '). 
Coll. Febr. and March 1893, March 1895. 
a) Tetramerous flower (fig. 1). 
b) Two tetramerous flowers, one of the ovary-cells a little 
smaller. This case may have been brought about by one of the 
sepals and its stamen and at the same time by one of the 
petals being doubled. The stigma of one of these specimens 
has the shape of a long funnel open at one side. 
c) A petal of a flower otherwise quite normal has grown 
together with its stamen and with an antisepalous stamen 
next to it. 
d) In the place ordinarily occupied by a petal with a stamen, 
we find a cross of the two (fig. 2). Most probably petalody of 
the stamen with suppression of the corresponding petal, because 
e) on the same plant a month afterwards a flower appeared 
with a stamen of which one of the anther-cells showed peta- 
lody (fig. 3) with the peculiar colour of the corolla: light orange 
with red specks. Another stamen of this flower shows the 
beginning of the same change viz. a small red speck at the 
foot of the anther. 
Notwithstanding these changes it remains possible that the 
part described in d) is the outcome of a petal and its stamen 
having grown together. 4 
J} Flower incompletely trimerous, there being only two petals. 
Consequently there is an open Space between two of the sepals. 
The latter show each a notch on the margins facing one another . 
(fig. 4). : 
Another flower of the same plant also lacks a petal, while _ 
the two sepals flanking the open space likewise show a notch, 
this time quite near the top. One of these Sepals shows more- 
1) Mr. Samira found this plant all over Java and also in the isle of Ambon.
