51116 to 51125— Continued. 



51118. CoKDiA NiTiDA Vahl. Boraginacese. 



"(No. 415a. July 1, 1920.) Seeds of j»M«eco. The mufieco is commonly 

 planted iu and about San Jose as a street tree, or as an ornamental 

 tree in parks and gardens. It reaches a height of 40 feet, and forma 

 a broad, shapely crown of deep-green foliage. It is quick growing and 

 rather soft wooded, so that limbs are sometimes broken ofE by storms. 

 The orange-red fruits, which are produced in clusters 4 to 6 inches 

 across, are individually the size of small cherries. They are not edible, 

 but since they remain on the tree a long time they ai'e of decorative 

 value." 



51119. Ckotalabia verrucosa L. Fabacese. 



"(No. 413a. July 1. 1920.) Seeds of a plant found abundantly at 

 Puntarenas, in abandoned or uncultivated places close to the seashore. 

 It seems less woody in character than Crotalaria retusa, and likely, 

 therefore, to make a better crop for use as a green manure. It reaches 

 about 18 inches in height, and bears attractive white and pale-blue 

 flowers. Evidently it is an annual. It should be tested as a cover 

 crop in the South, especially on sandy lands." 



51120. CtrpANiA sp. Sapindacese. 



"(No. 414a. July 1. 1920.) Paraiso. Seeds presented by Carlos 

 Werckle, of El Coyolar, Costa Rica. Mr. Werckle states that this is a 

 handsome ornamental tree, indigenous in the region about Coyolar, and 

 probably not described botanically. It should be tested in southern 

 Florida." 



51121. Paspaluii notatum Fluegge. Poacefe. Grass. 

 "(No. 418a. July 1, 1920.) Genf/ibrilJo. Seeds presented liy Alfredo 



Quiros. From sea level up to 5,000 feet this is probably tlie most impor- 

 tant of the pasture grass cultivated in Costa Rica ; above 5,000 or 6,000 

 feet it is injured by frost and is not, therefore, extensively planted. 

 In the lowlands it is especially esteemed ; it makes a compact sod, crowd- 

 ing out weeds and other grasses, and affording an abundance of nourish- 

 ing green forage, eaten readily by both horses and cattle. It rarely 

 grows more than a foot in height, and where pastured constantly does 

 not often reach more than 6 inches. For trial in the Everglades region 

 of southern Florida."

51122. PoLAKOwsKiA TAOAco Plttlcr. CucurbitaceiE. 



"(No. 422. July 1, 1920.) Seeds of taoaco. Among Costa' Ricans this 

 is one of the most popular of all vegetables, and it is regularly sold in the 

 market of San Jose during a large part of the year. 



" In general character the tacaco suggests the chayote. The plant, 

 which is commonly cultivated on arbors or allowed to climb over trees, has 

 a leaf resembling that of the chayote in shape but differing in texture ; and 

 the fruit, which falls to the ground when mature, is about 3 inches long, 

 • elliptic in outline. Frequently it has a few short spines about the base; 

 elsewhere it is smooth. When boiled it is considered to have a richer 

 000,1 flavor than the chayote, but the flesh is somewhat fibrous. 

 ■ '■ "The tacaco should be tried in the chayote-growing regions of the 



United States. Doubtless it would be possible to reduce the proportion 

 of fiber and otherwise improve the fruit by selection."
