Acacia seyal Delile (Mimosaceae.) 44923. Seeds from 

 the vicinity of Khartum, Egyptian Sudan. Presented by 

 Mr. F. G. Walsingham, Giza Branch, Ministry of Agricul- 

 ture, Cairo, Egypt. A small or medium-sized tree com-

Acacia spadicigera Cham. & Schlecht. (Mimosaceae.) 

 Bull-horn acacia. 44914. Seeds from Zacuapam, Vera Cruz, 

 Mexico. Presented by Dr. C. A. Purpus . "An interest- 

 ing shrub or small tree , with spreading branches armed 

 with thorns resembling the horns of a bull, and conse- 

 quently called, together with its allies, bull-horn acacia. 

 The thorns attracted the attention of early botanists 

 from the fact that they are usually hollowed out and 

 inhabited by stinging ants which serve as body-guards, 

 protecting the plant from herbivorous animals. The 

 present species is very closely allied to A. cornigera 

 of Linnaeus if not identical with that species. The 

 hollow, indehiscent pods, terminating in sharp spines, 

 enclose a number of hard seeds surrounded by a sugary 

 aril which is much relished by cattle and other ani- 

 mals." (W. E. Safford.) 



Annona cherimola Miller. (Annonaceae . ) 44841. Cheri- 

 moya. From Oran, Salta, Argentina. Presented by Mr. 

 S. W. Damon. "Seeds of Annona cherimola from rather good 

 fruit which I ate a few days ago. The trees which 

 bore the fruit withstood, last winter, a temperature 

 of about 15 Fahr." (Damon.)
