cluding the two families Ustilaginaceae and Tületiaceae. Complete 

 keys are given for the Separation of the genera and species. Under 

 each species is given the original citation, Synonyms, description, 

 hosts, type locality, distribution , illustration and exsiccati. The hosts 

 are given very fully, each host species being distinctly cited without 

 regard to the number which may belong to the same genus. A host 

 index completes the paper. The new species described are: Ustilago 

 Rickerii on Panicurn paspaloides from Cuba, U. Kellennanii on 

 Euchlaena luxurians from Guatemala, U. punctata on Polygonum 

 Newberryi from Washington, Tilletia Muhlenbergiae on Muhlenbergia 

 Schaffneri elongata from Mexico and T. Redfieldiae on Redfieldia 

 flexuosa from Nebraska. Perley Spaulding. 



Douglas, Gertrude E., The rate ofgrowth of Panaeohis reti- 

 nigis. (Torreya. VI. p. 157—165. 1906). 



This is an account of measurements of eighteen individual sporo- 

 phores of Panaeohis retinigis. It was found that the typical plant 

 requires from 4 to 5 days for the complete development after appea- 

 ring above the ground. The stem grows slowly at first, then very 

 rapidly for 40 to 56 hours, and then more slowly for about 24 hours 

 when it ceases. The pileus also grows slowly at first. It enters its 

 period of maximum growth just before the same ceases in the stem. 

 The growth is not more rapid at night than in the day time. The 

 growth-region of the stem is a few m.m. below the top.

Evans, P., Peach Rosette. (Bull. Missouri State Fruit Expt. Stat. 

 II. p. 1-10. 1904). 



This is a brief paper giving the characteristics of the disease 

 known as peach rosette. It first came to the notice of this Station in 

 1901 in an orchard near the Station grounds. It is known to be 

 present in seven different orchards at present. The immediate 

 removal of the diseased trees is recommended together with all 

 parts of the same, even to the leaves. A disease of plums has also 

 been noted which seems to be similar to that of the peach, but it is 

 not yet known whether it is the same. Perley Spaulding.
