SMILACINA RACEMOSA Desf. Vagunera racemosa (L.) Mo- 
rong.—The stem is simple and inclined to one side so as to 
throw the terminal panicle into an horizontal position. The 
flower consists of six divergent stamens and the pistil. The 
segments of the perianth are very small and never enclose 
the stamens, the anthers being evident from the early bud. 
With the exception of the anthers all of the parts of the flower 
are white. By an increase in the number of flowers the pani- 
cle of this species is rendered even more conspicuous than the 
raceme of the preceding. The plant is more common, butis 
not often found in patches like S. ste//ata. The flowers are 
proterogynous with long lived stigmas. Cross-pollination is 
further facilitated by the stamens being strongly divergent. 
Spontaneous self-pollination can hardly occur. 
There seems to be no nectar, ? and the few visitors noted 
only sought for pollen. The blooming season is from May 
7th to 30th. On the 17th, 18th and 23rd_the following vis- 
itors were observed:

On account of the shorter stamens, this may not be so ye 
as in the following. j

this species as an example of simple autogamy.
