CLASS DIANDRIA. 
orders, as in the preceding class, is derived from the number of 
stamens. 
There are no plants of the first order. 
DIANDRIA. 
The 2d Order contains the willow, (Salix,) which has long 
and slender aments, both of staminate and pistillate flowers, the 
two kinds being on separate trees. 
The order Triandria contains the fig, (Ficcs,) remarkable for 
containing the flower within the fruit, which is botanically con- 
sidered as a juicy receptacle, within which are concealed the 
Vninute flowers and seeds. The fig is peculiar to warm coun- 
tries. 
Tetrandria contains a parasite plant, the Misseltoej but one 
species is native to this country. The Druids considered this 
plant as sacred to the sylvan deities. Tradition relates, that 
where Druidism prevailed, the houses were decked with this 
plant, that the sylvan spirits might repair to them. 
The order Pentandria of the class which we are now consid- 
ering, contains the hemp, hop, and prickly-ash tree. 
Hexandria, contains the honey-locust and green briar. 
Octandria, has the poplar, (Populcs,) similar in natural char- 
acter to the willow. Several intermediate orders occur before 
we arrive at the 15th order, Monadelphia ; here we find the red 
cedar and the Yew, which belong to the cone bearing family, 
with the pine and cypress. 
We have now completed our remarks upon two classes which 
have imperfect flowers. Our review of these has been brief, when 
compared to the many interesting facts which presented them- 
selves in association, with the various important plants which 
we have passed in rapid succession ; but this very mass of in- 
teresting matter has compelled us to dwell less upon particular 
facts. We have now but one more class to investigate, in or- 
der to complete our view of the Linneean system.
