SEEDS AND PLANTS IMPORTED. 



34659. HoLCUS sorghum L. Giant Sudan sorghum. 



{Sorghum vulgare Pers.) 

 Prom Algiers, Algeria. Presented by Dr. L. Trabut. Received November 26, 

 1912. 



"This seed does not come from the original shoot, which has not flowered this season, 

 but from a seedling growing for some years. I consider that these seeds ought not to 

 give other than hybrid descendants." ( Trabut.) 



34661 and 34662. 



From Algiers, Algeria. Presented by Dr. L. Trabut. Received November 30, 

 1912. 



84661. Eucalyptus trabuti Vilmorin. Eucalyptus. 

 "A hybrid between Eucalyptus botryoides and Eucalyptus rostrata. Beautiful 



red wood, suitable for fiuTiiture. 



"A hybrid found by Dr. Trabut in sowing seeds of the Eucalyptus botryoides 

 which stood near a Eucalyptus rostrata. Always tends to revert to the male 

 parent. It is the first undoubted Eucalyptus hybrid, and the existence of 

 hybrids in this genus has been denied by Baron Ferdinand Mueller. This 

 hybrid is one of the most vigorous of the genus, and in a nursery row at the 

 Mustapha Experiment Station has crowded out the pure species." ( Trabut.) 



84662. Pyhus longipes Coss. and Dur. Wild pear. 

 "A tree of fair height, with few spines, and small, rounded, oval, suborbicular 



leaves; fruit small, globular, with very long peduncles. Occurs in the moun- 

 tains of Setif, Anini, and I'Aures, where it reaches its highest development." 



34663 and 34664. Solanum tuberosum L. Potato. 



From Bogota, Colombia. Presented by Senor J. M. Vargas Vergara. Received 

 December 4, 1912. 

 Tubers of the following; quoted notes by Senor Vergara: 



' ' Two varieties of tubers cultivated at this altitude and in the adjoining cold districts 

 to the east. Both are comestible, and, especially the former [S. P. I. No. 34663J, 

 appreciated for table use. They grow very well both in the mixed (turboso) soil of 

 the cold region and in the "humicos" and sandy soil of the coast (mesetas) and in the 

 very clayey soil. The black (negra) variety has shown more power of resistance 

 against the attacks of the Phytophthora infestans, which have made the acclimatization 

 of the varieties imported from other countries impossible. The diseases which affect 

 potatoes in other countries do not exist here." 



34663. 34664. 



"(No. 1.) Tuquerrena negra.'' "(No. 2.) Tuqu£rrena blanca." 



34665. Kokia rockh Lewton. Tree cotton. 



From Hawaii. Presented by Mr. J. F. Rock, Division of Forestry, Honolulu. 

 Received December 7, 1912. 

 See S. P. I. No. 31680 for description. 



"The material listed under S. P. I. No. 31680 was sentfrom the island of Hawaii under 

 the name of Gossypium drynarioides Seemann. Seemann published under the latter 

 name a poor description from an incomplete specimen in the British Museum, col- 

 lected on the island of Molokai by Nelson, the companion of Capt. C5ook. Seemann 

 did not see the fruit and described the calyx incorrectly, owing to the state of the 

 specimen. His species is now extinct and was confined to the island of Molokai. In
