most pronounced in the case of the lemon and least mjurious in case of 



the orange. Such orange trees as have not been seriously affected 



by this disease have made satisfactory growth and were carrjang their 



first fruits at the close of the fiscal year. A further introduction 



consisting of a few trees each of Valencia Late, Ruby Blood, and 



Navel oranges, Marsh Seedless pomelo, and Villa Franca lemon, 



have been obtamed during the past fiscal year, and these were planted 



on a different location, which it is hoped will prove better suited to 



their gi'owth. 



ANNONAS. 



A few seedUngs of the cherimoya (Annona cJierimoJa) were obtained 

 through the Office of Seed and Plant Introduction of this department 

 near the close of the pre^dous fiscal year. The growth of these plants 

 during the first few months led to the behef that the possibilities of 

 success could be increased by working these seedhngs upon the stocks 

 of some of the various species of Annona that are common on the 

 island, and experiments leading to that end were begun. Seedlings 

 of A. chenmola were found to unite readily with those of both the 

 bullock's heart {A. reticulata) and the sour-sop (.4. muricata), and 

 several inarched plants of the new species on these two stocks are now 

 available for planting. 



It has been observed at this station that there is a general tendency 

 for nursery plants to grow tall and leggy wdth insufficient strength to 

 support their weight, especially in the event of strong winds, and 

 in order to grow good, stocky plants severe top pruning or heading 

 in should be practiced regularly. 



MISCELLANEOUS INTRODUCTIONS. 



Among a number of new fruit introductions that have been sue- 

 cessfully made during the past year, passing notice should be given 

 the star apple {ChrysophyTlum cainito) , the akee tree (Cupania sapida) ,

 ■pigli la glabra) , the Spanish lime ( Melicocca bijuga) , the ceriman ( Mon- 

 stera deliciosa), the strawberry guava (Psidium cattle yanum) , and the 

 Otaheite apple (Spondias dulcis) . Various other economic plants, of

 {Carludovica palmata), the cocaine plant (Erythroxylon coca), Euca- 

 lyptus alba, vanilla {Vanilla planifolia) , and Xanthosoma sagittifolium 

 are a portion, have been introduced successfully %\dthin the year. A 

 white flowered variety of "cadena de amor" (Antigonoii leptopus), a 

 yellow flowered variety of Csesalpinia pulcherrima new to the island, 

 Honolulu holly (Schinus sp.), and the oak-leaved papaya (Carica 

 quercifolia) have also been received.
