 This genus was until 1897 held to include the Pampas 

 Grass (Gyneriiim argenteum), which has long been con- 

 sidered the finest of all tall, plumy grasses, as also the 

 most important, commercially, of all ornanieutal grasses. 

 Plumes of Pampas Grass are shipped in large quanti- 

 ties from California to Europe, and are dyed various 

 colors. In nature the plumes are silvery white, with 

 \arieties ringing from ro etocarmme Moltt and purple 

 Thej are often 2-3 ft long Pampas C i iss is giown com 

 mercially only in C alifomia The plumes are not col 

 lected m South America or shipped therefrom The 

 plumes of the male plants are much inferior to those of 

 the females and California growers exeicise the greate t 

 care to allow no male plants in the plantation In this 

 country the plumes are sold chiefl\ to persons of foreign

The popular name " Pampas Grass " is now unchange- 

 able, but the plant does not grow on the pampas or vast 

 grassy plains of South America, but in the mountains. 

 "All the evidence tends to show that it is confined to 

 the neighborhood of water courses iumI I" 1' |hi imus 

 where there is a constant and snii •<( 

 underground water." The manner in mis- 

 leading name became fixed is espln i i '^ '■ -injif, 



of Kew, in his excellent monograph ul il.i., i;roup 

 in G.C. III. 22:358, 378, 396 (1897). In this place Stapf 

 gives 5 species of Cortaderia, and another is added in 

 B.M. 7607. In S. America the Pampas Grass and some 

 of its allies are called Cortadero ; hence the generic 

 name Cortaderia. Cortaderias are widely distributed in

None of the following varietal names have botanical 

 rank, but they probably are fairly distinct horti- 

 culturally, and so far they have appeared only in 

 connection with the name Gynerium. Var. mon- 

 strdsum is perhaps the most robust, and var. nanum 

 (which grows about 3 ft. high), the dwarfest. The 

 others here mentioned are supposed to be the same 

 height as the type. A slender form with narrower foli- 

 age is var. felejans, with Ivs. a fourth of an inch wide

 describe it as a rosy-plumed variety. 



When advertised under Cortaderia, these names 

 should all have the feminine endings, as monstrosa, etc. 



Cortaderia jubata, Stapf (Gijnennm jubMum. Lem. 

 G. arcmitn-nebuldsum, Hort.). Differs from Pampas 

 Grass in the rather laxer, more graceful plume, with 

 longer, more flexuous, nodding branches, somewhat 

 smaller spikelets, more delicate glumes, and in the 

 longer, very slender staminodes of the pistillate fls. 

 The plume is lavender-colored, and the plant has been 

 killed by a temperature of 3° F. Grows in a dense 

 tuft, perennial, but with biennial culms: spiki'lrls ;!-.'- 

 fid. The plume is 1-2 ft. long. B.M. 7i;n7. il.c. III.
