1894.] Botany. 175 
Whence it appears that this vast group, too, has doubled since 1849. 
Then in regard to the Fungi the results obtained in the active and 
multiplied researches of the last twenty years have surpassed all ex- 
pectation. The number of species, in fact, reported in Vol. X of my 
Sylloge Fungorum and which goes to May of the current year, 1892, 
attains the marvellous sum of 39,663, that is to say, that in thirty years 
the group of Fungi has almost quadrupled. 
We should therefore join to 
Sum’ Total 131,104 (above indicated) 
For the Liverworts 1,400 
For the Fungi 27,773 
For the Algae 5,978 
and we have 166,255 
This sum is deduced from positive data and it is annoying that on 
the other vegetable groups there is no information summing up the 
latest additions. However, to judge from the most recent botanical 
periodicals, as the Botan. J ahresbericht, the Botan. Centralblatt, the 
Monographiae Phanerogamarun, etc., etc., one cannot deny that the 
osses' have doubled since 1851 and that the Phanerogams and Ferns 
have increased almost five per cent.’ 
Thus we shall have: 
Sum total preceding 166,255 
For the Phanerogams an increase of 5,011 
For the Ferns 134 
For the Mosses 2,306 
Total 173,706 
Which sum, then, represents with great approximation the true 
number of species of plants known up to the present time, that is 
105,231 Phanerogams and 68,475 Cryptogams thus distributed : 
‘The celebrated bryologist Schimper in the preface to his Synopsis Muscorum 1860- 
1876, thought that the Mosses of the whole world, when known, would amount to 
More than 8,000 species. 
*The publication of the new and great Nomenclator Plantarum is eagerly awaited, 
already in part printed at London by the munificence of Darwin. From this one will 
be able to state exactly the real increase of the Phanerogams in these last years.
