has a medulla derived from the fundamental tissue, and is characterized by 

 the presence of foliar and ramular lacunae, or by ramular lacunae only; the 

 siphonostelic central cylinder sometimes ceases to be obviously tubular in 

 the adult, and in such cases may be termed adelosiphonic ; the siphonostelic 

 central cylinder is primitively concentric, but in the Angiospernis, Gymno- 

 sperms, Osmundaceae, etc., has become collateral by reduction ; the pith is 

 to be regarded as an inclosed portion of the fundamental tissue. The phylo- 

 genetic features of the results are as follows : There are two phylogenetic 

 types of tubular central cylinder, viz., that in which only ramular gaps are 

 present, and that in which both ramular and foliar gaps occur, the former 

 termed cladosiphonic, and the latter phyllosiphonic ; the use of these con- 

 stant and characteristic anatomical features results in the division of the 

 Vasculares into two great primitive stocks — the Lycopsida, which are 

 cladosiphonic and palingenetically microphyllous, and the Pteropsida, which 

 are phyllosiphonic and palingenetically megaphyllous ; the former including 

 the Lycopodiales and the Equisetales, the latter the Filicales, Gymnosperms, 

 i and Angiosperms.— J. M. C. 



Items of taxonomic interest are as follows : Alice Eastwood (Proc. 



Calif. Acad. Sci. III. Bot.a: 285-293. 1902) has described new species of 

 Streptanthus, Polygonum, Eriogonum, Garrya, Convolvulus, Castilleia (3), 

 Mimulus, Phacelia, Gilia, Cryptanthe, Aster, and Madia, all from the Sierra 

 Nevada mountains of California.— W. A. Kellerman (Jour. Mycol. 8: 50- 

 51.//. I, 1902) has published a new species of Rhytisma on Ilex. — J. C. 

 Arthur [idem 51-56) has published 3 new species of Puccinia. — Ellis and 

 EvERHART {idem 62-73) have published 59 new species of fungi from the 

 vicinity of Tusk egee, Alabama. — P. Henxings (Hedwigia4i : loi-i 18. 1902), 

 in his first paper on Putteman's collection of fungi from Sao Paulo, has 

 described as new genera Piittemansia (Pezizaceae), Pseitdomelasmia (Lepto- 

 stromataceae), and 7>/r^^vv//w (Mucedinaceae); and from the Javanese col- 

 lection of Zimmermann the same author (/V/f/w 142) has described a new 

 genus {Zimmermaimiella) of Dothideaceae.— J. B. S. Norton (Trans. Acad. 

 Sci. St. Louis 12 : 35-4 r.//^.j--t?. 1902) has published new species of Cyperus, 

 Argemone, and Brauneria from the southwestern U. S.— T. Makixo (Bot. 

 Mag. Tokyo 16:119. 1902) has published a new ^cnws {Semiaquilegia) oi 

 Ranunculaceae from Japan, said to be intermediate between Aquilegia and 

 Isopyruni, and founded on hopyrum adoxoides.—). Matsumura (Jour. Coll. 

 Sci. Tokyo 16 : pt. 2, pis, 4, 1902), in his revision of the Japanese species of 

 AInus, has described 3 new species. — K. Yendo (/V/<?;////;. 7), in a revision 

 of the "Corallinae verae" of Japan, has described 20 new species. — Elmer 

 D. Merrill (Rhodora 4: 142-147. 1902), in "Notes on N. Am, grasses, 

 has described new species of Panicularia. Poa, Bromus. and Elymus,
