Papaveracesee and Capparideee. Orders less important for early 
study were omitted. At the commencement of this little work 
Myrtaceze came under consideration, and it was shown, that in 
the series of orders with free or separated petals (Choripetalez 
or less accurate Polypetalez), they occupied a place along with 
those, which have the fruit immersed into the adnate tube of 
the calyx. Had the limits, assigned to this first school-book, 
admitted of space, then umbelliferous plants, of which the Carrot 
and Parsnip are well known examples, could have been treated 
by choosing native plants for demonstration ; the same may be 
said of Onagrez, exemplified in gardens by Fuchsia, and of 
several other orders, which in primary respect to petals and 
fruits should be placed near Myrtacee, if a strictly systematic 
Sequence was required. 
Explanation passed on from Myrtacee to ordinal groups of 
widely distant affinity, because it was thought, that among 
native plants the young disciple would most easily obtain the 
needful instructive objects from easily recognised trees. Hence 
Casuarine and Conifere, both without any petals, came under 
review, and so the Leguminosee. The latter form a transit from 
_ orders with free petals to orders with connate petals, if this 
characteristic is adopted as a primary one for classification. 
Leaving here out of consideration the Proteaceze (some in fruit 
not unlike to Leguminose), the Santalaceee and Loranthacee, 
the floral envelope of which may be considered either petaline or 
sepaline according to various views and interpretation of their 
floral structure, we advanced to orders with almost invariably 
and permanently connate petals (gamopetalez), or less logically 
called also monopetaleee or synpetalee. Among these Com- 
positee (still containing arborescent species), Campanulacee, 
Stylideze and Goodeniacez belong to the series with fruits connate 
with the calyx, whereas Epacridez pertain to that long series of 
families, in which the petals are united and the fruit remains free 
from the calyx. Before leaving the dicotyledonous plants and 
proceeding to Monocotyledonez, still two more orders of the 
series, to which the Epacride pertain, are tobe interposed, 
because the one contains here several poison-plants, with which
