92471 to 92477. Triticum aestivum L. 

 (T. culgare Vill.). Poaceae. 



Common wheat. 



From Kenya, Africa. Seeds presented by 

 R. J. Lathbury, Plant Breeder, Plant 

 Breeding Station, >joro. Received April 

 6, 1931. 



92471. Equator. The only variety grown 

 at the higher altitudes between 8.000 

 and 9,000 feet. Highly resistant to 

 yellow rust, but susceptible to stem 

 rust forms Nos. 17 and 21. A heavy 

 yielder that matures in 7% montbs at 

 9,000 feet. Sown with the start of 

 the rains in April to June and har- 

 vested in the- dry season from Decem- 

 ber to February. This variety origi- 

 nated as a selection from a field of 

 wheat growing on a farm called Equa- 

 tor at Njoro. Sometimes known 

 locally as K. 1. 



92472. Kenya Governor. Grown at alti- 

 tudes up to 7,000 feet. Too susceptible 

 to yellow rust at higher altitudes. 

 Resistant to one form, No. 17, of 

 stem rust, but susceptible to form 21. 

 Resistant to leaf rust. Matures in four 

 months at 5,000 feet. A useful stop- 

 gap, but one that will fall out of culti- 

 vation as new rust-resistant varieties 

 are produced. 



92473. Kenya Standard. Similar to 

 Kenya Governor, but is resistant to 

 both physiologic forms of stem rust. 

 Nos. 17 and 21 ; susceptible to leaf 

 rust. Does not yield as well as 

 Kenya Governor, but has stronger 

 straw and tighter chaff. 



92474. B. F.. 2 36 C. 1 (L.). Similar to 

 Kenya Governor and with the same 

 stem-rust resistance, but a better 

 yielder. Little of this variety is 

 grown. 



92475. K. 2 R. 5 (L. 2). A new Njoro 

 wheat which is resistant to forms Nos. 

 17 and 21 of stem rust and also to 

 yellow rust. It matures in 5% to 6 

 months at 7,000 feet altitude and in 

 6 to 614 months at higher altitudes. 



92476. Golden Ball. A wheat grown at 

 7,000 to 8,000 feet altitude. It is sus- 

 ceptible to all rusts, but generally 

 gives a crop. Not largely grown. It 

 originated from South Africa, where 

 it is known as Groot Korn. Matures 

 in six months. 



92477. K. 2 G. 6 A. 9 (L.). A new Njoro 

 wheat which is resistant to forms 

 Nos. 17 and 21 of stem rust. It 

 matures in 5% to 6 months at 7.000 

 feet altitude and in 6 to 6% months 

 at higher altitudes. 



92478 to 92486. Casuarina spp. Cas- 

 uarinaceae. 



From Australia. Seeds presented by Dr. 

 Alexander McTaggart, Senior Plant In- 

 troduction Officer, Canberra. Received

92478. Casuarina decussata Benth. 



A small tree closely resembling Casu- 

 arina torulosa, with slender elongated 

 branches arranged in fours, but the 

 angles are very acute, and two of them 

 are more prominent than the others. 



92479. Casuarina fraseriana Miquel. 



A tall erect shrub or small tree closely 

 related to Casuarina distyla, with leaf- 

 less, rigid branches and with the leaves 

 represented by very small scales in 

 whorls. 



For previous introduction see 73914. 



92480. Casuarina huegeliana Miquel. 



A shrub or small tree, native to West- 

 ern Australia, with round branchlets ar- 

 ranged in whorls of 8 to 12. 



92481 and 92482. Casuarina inophloia 

 Muell. and Bail. 



A small tree with loose fibrous bark 

 and thin slightly streaked branchlets in
