 tion: poUination Studie s. (Bull. N". 289. U. S. Dept. Agr. 

 Sept. 21, 1915.) 



A detailed study of floral structure, behaviour of pollen in ger- 

 mination when selfed or crossed, and insect activities on Trifolium 

 pratense, showing that sterile ovules, without egg-development, 

 characterize early flowers, that selfed pollen rareiy if ever pene- 

 trates to the embryo-sac, that Apis, collecting pollen, is about as 

 efficient a poUination as is Bomhus, which Visits the flowers for 

 their deepseated nectar, and that existing mechanical devices for 

 effecting crossing cause lessened seed production because of the 

 mechanical injur)^ they inflict. Trelease.

Die Pflanze wird genau beschrieben (Synonyma z.B. Cyttostiriis 

 cruciformis VVilld., Phalaris cruciforinis Ait.). Sie ist an sumpfigen 

 Stellen und an Flüssen zu finden u.zw. in Italien, ganz S.O.- 

 Europa, Ungarn, O. -Europa, N.- und Mittelasien nach 

 Alaska, bis Minnesota. In • Deu tschland eingeschleppt. Von 

 Abarten sind die in Russland vorhandenen beachtenswert; var. 

 ramosa Pacr., var. haicalensis Kunezow, var. minor Pacr., in N.- 

 Amerika die var. ttniflora. In Russland speziell gedeiht die 

 Pflanze nach Kusnezow sehr gut und leidet nicht durch Pilze; 

 sie bringt viele Samen hervor, was die Anzucht des mehrjährigen 

 Grases sehr erleichtert. Die reifen Aehrchen heissen im Handel 

 „Samen". Anbauversuche in Deutschland wären recht erwünscht.

 vely in Florida and the West Indies, and for whom a number 

 of Southern species of palms, morning glories and orchids were 

 named. He was born January 23, 1838, was educated at Milles- 

 viUe Normal School, taught school, took his undergraduate de- 

 gree at Lafayette College in 1868, took his medical degree at the 

 University of Pennsylvania, in 1872, and because of failing 

 health collected in the tropics. His herbarium was largely distributed 

 to Franklin and Marshall College, Lafayette College, New York 

 Botanic Garden, Academy of Natural Sciences of Philadelphia, 

 He died August 25, 1881. A bibliography and portret were included.
