SUMMARY OF CURRENT RESEARCHES RELATING TO 
slightly differentiated from the Monocotvledones, from which those now 
in existence may possibly have sprung. 
Zoocecidia.*— Herr G. Hieronymus enumerates the galls found on 
European plants. He classifies them under three heads, viz. : — Helmin- 
thocecidia (13), Acarocecidia (273), Entomocecidia (517) arranged 
under Hemipterocecidia, Dipterocecidia, Hymenopterocecidia, Lepido- 
pterocecidia, and Coleopterocecidia. Under each species of plant are 
enumerated the insects which produce galls upon it, and the European 
distribution, as far as it is known. 
B. CRYPTOGAMIA. 
Classification of the Vegetable Kingdom. f— Prof. F. Ardissone 
proposes a classification of the Vegetable Kingdom, of which the 
following are the main features : — 
I. Prothallogam.e. 
1. Angiogamae. 
Class 1. Angiospermas. 
Class 2. Gymnospermae. 
2. Gymnogamae. 
Class 3. Heterosporae (Marsilineas, Selaginellineae). 
Class 4. Isosporeae (Lycopodineas, Filicineae, Equise- 
tineae). 
II. Cormogam.e. 
1. Schisfogamae. 
Class 5. Charineee. 
2. Aulogamae. 
Class 6. Sporoginere (Bryinete, Sphagnineae, Junger- 
mannieae). 
III. Thallogam^:. 
1. Telogamae. 
Class 7. Cystocarpeffi (Florideae). 
2. Zygogamae. 
Class 8. Esucophuseae (Dictyotineae). 
Class 9. Blephariphuseae (Fucoideae, Vaucherineae, Bry- 
opsidineae, Confervineae, Chytridineae). 
Class 10. Ablephariphuseae (Peronosporineae, Mucorineae, 
Zygnemineae, Desmidineas, Diatomineae). 
IV. Agam.e. 
Class 11. Basidiosporeae (Agaricineas, Lycoperdineae, 
Tremellineae, Uredineae, Ustilagineae). 
Class 12. Ascosporeae (Tuberiheae, Pezizineae, Hypoxyli- 
neae, Parmeline*, Saccharomycineae). 
Class 13. Myxosporeae (Endomyxaceae, Ceratiaceae, Acra- 
siaceas, Plasmodiophoraceae). 
Class 14. Schi zosporeae (Nostochineae, Chroococcoideae, 
Bacterineae).
