SUGGESTIONS TO STUDENTS 
5 
Compositae, Rubiaceae ; Labiatae, Primulaceae or Myr- 
sinaceae, Ericaceae; Umbelliferae, Malvaceae, Leguminosae, 
Rosaceae, Cruciferae, Ranunculaceae, Caryophyllaceae, 
Betulaceae or Piperaceae ; Orchidaceae, Liliaceae, Grami- 
neae ; Coniferae ; Selaginellaceae ; Polypodiaceae. 
After a considerable number of plants and flowers of 
these orders has been examined, dissected, described, and 
sketched, the student will be able to refer to its relationships 
any unknown plant of these orders that may be given to 
him. He will now have a practical acquaintance with the 
class of facts with which systematic botany deals, and should 
study the principles of the subject (see Chapter II.) and 
the different systems of classification in use. He should 
not however be content with merely finding out the order to 
which an unknown plant belongs, but should further study 
the sub-division of these orders into their tribes ; this will 
help him in grasping the principles of classification. Lastly, 
with the aid of Hooker’s British Flora or the similar work 
referring to his own district he should endeavour to identify 
the genus and species of all wild plants which he recognises 
as belonging to the orders he has studied. While he studies 
the classificatory details of flowers &c., he should of course 
pay attention to interesting features in their morphology or 
natural history, and Part II. will aid him in this. The 
various subjects treated in Chapter III. should also be 
worked at one by one and studied in a botanic garden, 
in museums, and in the field, with the aid of the details 
given in Part II., and with reference to original papers for 
further information. A third season may be employed in a 
similar way by increasing the number of natural orders 
studied ; the new ones will group themselves in the mind 
round those already familiar. It is best not to attempt to 
add too many new ones at once to the old; about 40 — 50 1 
1 These should at any rate include the following orders : Campanu- 
laceae, Cucurbitaceae, Acanthaceae, Scrophulariaceae, Solanaceae, 
Boraginaceae, Asclepiadaceae, Apocynaceae, Myrtaceae, Melastoma- 
ceae, Cactaceae, Sapindaceae, Anacardiaceae, Euphorbiaceae, Rutaceae, 
Podostemaceae, Saxifragaceae, Papaveraceae, Nymphaeaceae, Cheno- 
podiaceae, Polygonaceae, Proteaceae, Moraceae, Fagaceae, Salicaceae, 
Casuarinaceae ; Zingiberaceae, Iridaceae, Amaryllidaceae, Bromelia- 
ceae, Araceae, Palmae, Cyperaceae, Potamogetonaceae ; Gnetaceae, 
Cycadaceae ; Isoetaceae, Lycopodiaceae, Equisetaceae, Salviniaceae,
