tion of plants made by Dr. E. Palmer, in 1887, chiefly about Guaymas, 

 Mexico. The season was very dry and unfavorable, and this, too, in a 

 country that is normally dry and unfavorable, and yet 415 native species 

 were collected, 89 of which are wholly new. This region of the Gulf of 

 California is one of great interest botanically. It is probably the north- 

 em limit on the Pacific coast of such tropical genera as Rhizophora, 

 Hsematoxylon, Citharexylum, Ficus, etc. Among the 415 species, there 

 are 50 Graminese, 50 Composite, 44 Leguminosae, and 32 Euphorbiacese. 

 The important orders Ranunculacese, Rosaceoe, Saxifragaceae, Umbelli- 

 fene, Ericaceae, Cupuliferae, Coniferae, ana Orchidacere are wholly unrep- 

 resented. Excluding Cyperacea3 and Gramineae, there are only 5 endogen- 

 ous species in the entire collection. The new genera proposed are Malperia 

 (Agerateae among Composite), Ptlucha (Plucheineae among Composite), 

 and Pattalias (Asclepiadaceae). The second part contains descriptions of 

 new species, chiefly Californian, and also proposes the restoration of Sisy- 

 rinchium anceps Cav. Dr. Watson finds that two forms can be readily 

 distinguished, one {S. anceps Cav.) with branching stems and globose 

 strongly pitted seeds less than half a line in diameter, the other (S. an- 

 gustifolium Mill.) with simple stems and angled less pitted seeds about 

 twice larger than the other. 



Saccardo's Syllojje Kunjforuni. 2 



Two more volumes of the Sylloge are before us, volume VI and the 

 second part of volume VII, and but one volume remains to complete this 

 great work. The invaluable service to mycologists in thus bringing to- 

 gether in convenient form descriptions of all known fungi has already 

 been alluded to in notices of the earlier volumes. The present parts 

 follow the treatment already well established, and which it is unnecessary 

 to describe in this connection. 



The sixth volume contains descriptions of 3011 species, being more 

 than quadruple the number belonging to these orders known when Fries 

 published his Epicrisis in 1838, and still the harvest of new species is 

 unabated. 



The first part of the seventh volume was noticed recently; the sec- 

 ond part, now before us, deals with the Ustilagineae and Uredineae, two 

 specially interesting groups of parasitic fungi. As there have been many 

 collectors of these plants in North America, there are consequently a 

 considerable proportion of the species accredited to this country— of the 



Ustilagineae nearly one-fourth. 



As in every other work touching upon the classification of these 

 groups, the protean changes of synonymy bring to light old, new, or little
