ITEMS OF TAXONOMIC INTEREST are as follows: N. L. GARDNER (Univ. 
Calif. Publ. Bot. 2:'169-180. pl. 18. 1905) has described a new genus (Nigro- 
sphaeria) of ascomycetous fungi, parasitic on Pseudhydnotria, one of the Tuber- 
aceae.—N. L. Brirron (Bull. N. Y. Bot. Garden 4:115-127. 1905), in a second 
paper entitled “Contributions to the flora of the Bahama Islands,” has described 
new species of Coccolobis, Caesalpinia, Canavalia, Hibiscus, Heliotropium (2), 
Lantana (2), Cestrum, Stemmodontia, and Anastraphia.—W. A. MvrriLt in his 
twelfth paper on the Polyporaceae of North America (Bull. Torr. Bot. Club 
32: 469-493. 1905) has described twelve new genera of this family (Irpict- 
porus, Dendrophagus, Spongiporus, Rigidiporus, Earliella, Cubamyces, Coriolel- 
lus, Microporellus, Flaviporellus, Aurantiporellus, Aurantiporus, Pycnoporellus, 
Phaeolopsis), making new names for species formerly referred to Boletus, Poly- 
porus, Fomes, or Trametes. Earliella alone is possibly new.—K. K. MACKEN- 
zie (idem 495-506) describes three new varieties and creates two new specific 
names under Onosmodium, and refers O. Thurberi to Macromeria Thurbert.— 
In a sixth paper on Crataegus (Rhodora 7:162-164. 1905) C. S. SARGENT 
describes two new species of Tomentosae.—M. L. FERNALD (idem) refers the 
common Symphoricarpos racemosus Auct., with leaves glabrous beneath, to the 
new var. laevigatus; those with leaves pilose beneath to the type, and those with 
leaves whitened beneath to var. pauciflorus—A. Borzi establishes (Nuova Notarisia 
16:20. 1905) two new genera of Chrococcaceae, Planosphaerala and Bacularia.— 
W. A. SercHeLt describes (idem 59-63) a new genus, Peyssonneliopsis, 
a parasitic alga distributed under a manuscript name in 1993, as no. 649 
of the Phycotheca Boreali-Americana—Max FLEISCHER (Hedwigia 44:301- 
329. 1905) describes as a new genus of the Indian Archipelago, Aerobryopsts, 
to receive ten species mostly belonging to a section of Neckera, Eriocladium, 
which, though preoccupied, was raised to generic rank by DusféN. A dozen 
new species, all issued in Exsicc. Musci Archipel. Ind. Series VII. 1904, are 
also described.—F. BusnAk and E. KapAt (idem 350-358) describe new species 
of fungi from Bohemia; Phyllosticta (3), Vermicularia (1), Ascochyta (3), Diplo- 
dina (1), Leptothyrium (4), and Ramularia (r)—H. Curist (idem 359-379) 
publishes the list of ferns,collected by Ute in the Amazon region, including one 
new species each of Elaphoglossum, Polypodium, Pteris, Lindsaya, Asplenium, 
Aspidium, Alsophila, and Danaea.—The whole of the first part of vol. 38, Engler’s 
Bot. Jahrb., is devoted to descriptions of new species of African plants. The 
following new. genera are established: by R. SCHLECHTER (Bot. Jahrb. 38:1-56. 
1905) Auxopus, Genyorchis (Orchidaceae), and Neoschumannia (Asclepiadaceae) ; 
by H. Harms (idem 74-79) Platycelyphium and Stemnocoleus (Leguminosae);

Tridesmostemon (Sapotaceae).—C. R. B. 
In THE large literature on Bordeaux mixture, secondary physiological effects 
on plants, not due to the fungicidal action of the mixture, have frequently been 
described. These effects are of two kinds: first, a stimulating effect, resulting
