implies (which is of Greek orgin), and is made 
up of two words, angios and sperma. 
Now, the sub-classes are divided into three 
divisions, the Polypetalous (many petals), 
Monopetalous (one petal) and the Apetalous 
(without petals). 
Let us now return to class two of the first 
series, which is divided into the Endogenous 
or Monocotyledonous, and commonly known as 
the inward growers; and the plants with one 
cotyledon, or one seed leaf, whose stems are 
made up of fibres, running lengthwise and in- 
termingling with the soft internal tissues, the 
hardest part of the plant or tree being on the 
outside, as we find it in the cornstalk, palm 
and bamboo. The leaves are all paralleled- 
veined, and rarely branching until near the 
summit. These inward growers are divided 
into three divisions: the first or spadeaceous, 
includes the palms, arums, etc., while the 
petaloidous division includes the water p/antain, 
trillium, spiderwort, lillies, etc., and their or- 
ders, and the third and last g/umaceous division 
includes the rush, sedge and grass families or 
orders. 
Let us now call your attention to the second 
series in the great divisions or classes, and 
that is the flowerless or cryptogamous plants 
These are also divided into classes, beginning 
at class 3, Acrogens, which includes the ferns, 
horsetails and club mosses; class 4, which in- 
cludes the mosses and liverworts; and class 5, 
which includes the sea weeds or a/g@, and the 
mushrooms or fungt.
