OCTOBER 1 TO DECEMBER 31, 1917. 69 



45612. Pyrus mamorensis Trabut. Malaceae. Pear. 



From Rabat, Morocco. Seeds presented by Commandant de Beaucoudrey, 

 Inspector of Forests, at the request of Dr. L. Trabut, Algiers, Algeria. 

 Received December 22, 1917. 



" Seeds of a Moroccan pear which occurs with the cork oak in the forest of 

 Moroccan Mamora. It is very resistant to dryness in the sandy noncalcareou3 

 soils. The vigorous tree will probably form a good stock. The fruit is rather 

 large, and the seeds are very large." (Trabut.) 



45613 and 45614. Passiflora spp. Passifloracese. Granadilla. 



From Caracas, Venezuela. Seeds presented by Mr. H. Pittier. Received 

 December 26, 1917. 



45613. Passiflora sp. 



Possibly a hybrid between Passiflora eduUs and P. maliformds, as the 

 seeds do not agree with either, although somewhat resembling each. 



45614. Passiflora ligularis Juss. Sweet granadilla. 

 " Unquestionably one of the best of the granadillas. In Guatemala it 



is common at altitudes of 4,000 to 7,000 feet, but I have never seen It in 

 the lowlands; it appears, therefore, that it is adapted to subtropical 

 climates and, judging from its presence in portions of Guatemala almost 

 too cold for the avocado, I feel that it ought to succeed in California. 

 The behavior of other species, such as Passiflora edulis, in that State in- 

 dicates that conditions in general are favorable to the passifloras, and 

 the question has generally been one of hardiness. Many species tested in 

 California have proved to be too tender. P. ligularis, with slight protec- 

 tion during the first winter or two, certainly ought to thrive in the 

 southern half of the State. 



" In Guatemala it is a rampant climber, scrambling over trees and 

 buildings and covering them with a canopy of green. It goes to the tops 

 of trees 35 or 40 feet in height. Its foliage is bold, the large cordate 

 leaves being as much as 6 or 8 inches in length. 



" The ripening season- commences in early fall and extends through 

 the winter. Large plants bear abundantly, yet I have never seen a vine 

 so laden with fruits as some of the plants of Passiflora edulis which 

 grow in California gardens. The fruits are commonly 21 inches in 

 length and deep orange-yellow in color. Sometimes a purple-fruited 

 variety is seen. The brittle outer shell or pericarp, when broken away at 

 one end, exposes the small elliptic seeds individually inclosed in a juicy, 

 white aril. The aroma of the fruit is delightful; it may properly be 

 termed perfumed. The flavor is equally pleasant and, unlike many 

 other passifloras, is not unduly acid. The fruit is commonly eaten out 

 of hand, for which mode of use it seems best adapted. One can consume 

 a large number of them without any ill effects. 



" The fruits are often brought into the markets of Guatemala upon 

 the backs of Indians from distances of a hundred miles. The pericarp 

 is so tough that it is not easily bruised, hence the fruit can be trans- 

 ported without difficulty. It is attractive in appearance and so popular 

 in Guatemala that it realizes higher prices in the markets than most 

 other fruits which compete with it. 



"The term granadilla (diminutive of granada, Spanish for pome- 

 granate) is applied in tropical America to the fruits of various passi-
