41924. Arundinaria pumila Mitford. Poaceae. Bamboo. 



From San Francisco, Cal. Roots presented by Mr. John McLaren, Superin- 

 tendent of Parks and Squares. Received February 15, P.U6. 



" A very pretty and ornamental dwarf bamboo. At first one might be 

 tempted to confound this species with Arundinaria humilis, but closer observa- 

 tion leads to the conviction that it is quite a distinct plant. It is less tall, the 

 leaves are darker green, shorter, and not so broad, and do not taper so grad- 

 ually to a point as those of Arundinaria humilis. The tessellation is closer, the 

 teeth of the serrated edges are, if anything, less conspicuous, and the nodes are 

 less well defined and far less downy; but, on the other hand, they have a waxy 

 bloom not to be found in A. humilis. The stem is much more slender and more 

 entirely purple except quite at the base. 



"The culms are about 15 inches high or rather more, round, and very slender. 

 The leaves are about 5 inches long by a half to three-quarters of an inch in 

 breadth, bright green in color. Altogether a brilliant little plant, quite hardy, 

 and a very effective ornament for some rocky nook, where, as it does not seem 

 much inclined to run at the roots, it may better be kept within bounds than 

 some of its family." (Mitford, The Bamboo Garden, p. 98.) 



41925. Caragana arborescens Lam, Fabaceae. Siberian pea tree. 



From Indian Head, Saskatchewan, Canada. Presented by Mr. Norman M. 

 Ross, Forestry Branch. Received February 11, 1916. 



41926 and 41927. 



From Horqueta, Paraguay. Presented by Mr. Thomas R. Gwynn, through 

 Mr. Daniel F. Mooney, American minister, Asuncion. Received Febru- 

 ary 12, 1916. 



41926. Citrus medica L. Rutaceae. Citron. 

 Brazilian citron. 



41927. Cucuebita maxima Duchesne. Cucurbitacea?. Squash. 

 A type that may prove of value in the Southwest. 



41928. Piiaseolus semierectus L. Fabaceae. 



From Chuluota, Fla. Presented by Mr. Lawrence Swanson. Received 

 February 12, 1916. 



" Jauguario. My introduction from Cuba, where I found it growing along the 

 banks of the River Jaugua and which has proved of more value as a cover crop 

 than many old stand-bys. It has interested everyone who lias seen it growing. 

 It is a perennial and with me lias grown again after the tips are frosted. The 

 seeds are very scarce. From observation I think the best results will be had 

 after the first year from seed; in its second and third year it seems (o master 

 the ground and spreads rapidly." (Swanson.) 



41929. Indigofera argentea L. Fabaceae. Indigo. 



From Cairo, Egypt. Presented by Mr. Thomas W. Brown, director, horti- 

 cultural division, Ci/.eh Branch, Ministry of Agriculture. Received 

 February 14, 1916. 

 "This species is the only one cultivated In Egypt for dye production." 

 (Brown.)
