304 THE JOURNAL OF BOTANY 
Stokes, and that the more recent ones are based upon miscon- 
ception, let us examine the evidence afforded by the works of 
innzeus. 
The herbarium shows that No. 11, labelled C. canescens, is 
represented by C. polygama Schukhr, and that the plants labelled 
C. brizoides are partly represented by C. canescens. erefore, if 
the h ium were the decisive factor, C. polygama Schukhr = 
C. canescens L.. But Linneus’s C. canescens (Sp. Pl. 974) is 
rimarily based upon ‘“ Carex spiculis subrotundis remotis sessili- 
bun obtusis androgynis, capsulis ovatis obtusiusculis. Fl. Swec. 
figure (Hl. Pruss. t. 32), “Gramen cyperoides spicis 
divulsis,” which Linnzus cites, is not only the plant, but contains 
the very word “curtis” which Goodenough uses to designate his 
C. curta. 
only gives C. divulsa for “Suec. mer. med.,” reas C. canescens 
is found “in pal. aquosis totius Suec. frequentis.” Dr. Murbeck 
has, however, found C. divulsa in S$. Norway; see Bot. Notiser, 
1885, 82. 
We may therefore with s fidence assume that the species 
afterwards called C. curta Good. is the C. canescens of the Species 
and the somewhat faulty synonymy; and we may dismiss the idea 
that it is in any way synonymous with or related to the widely 
different species C. divulsa.

Cardiff ; one radiate type attracted his notice as early as 1891, 
and the occurrence of other forms led him “to submit all the 
forms to a process of testing by means of experimental ‘ pedi- 
g tu These experiments began in 1905 and are still 
in progress. 
- Dr. Trow recognizes four segregates, of which “ hybrids pro- 
bably occur in every possible combination”; some have been 
obtained experimentally ; a full account of the experiments will
