These are old varieties of American origin which are being cultivated in New 

 South Wales. They have been reintroduced from New South Wales for special 

 studies by potato experts. William Stuart, of the Bureau of Plant Industry, 

 has furnished the descriptive notes from old American catalogues. 



55510. Adirondack. This variety is a hybrid with White Pcachhlow. 

 It is distinguished from the latter in its upright habit and larger 

 bright-green leaves. The red-skinned, almost perfectly spherical tubers 

 are much clustered; the flesh is pure white. (Adapted from Potato 

 Catalogue of B. K. Bliss d Sons, J881, p. 5.) 



55511. Brownell's Beauty. The foliageis deep green and very healthy: 

 the tubers grow compactly in the hill and are easily dug, ripening in 

 about three months from the time of planting. The tubers are 

 medium to large, oval or somewhat flattened with the eyes few and 

 nearly even with the surface; the skin is reddish or deep-flesh color: 

 the flesh is white, fine-grained, and very delicate. For the table, wlien 

 baked or boiled, they are equal to the best. (Adapted from Potato 

 Catalogue of R. K. Bliss & Sons, 1S74, P- 4-) 



55512. "Carmen No. 1. (Synonym linral Xcir YarL- \o. ./. ) This is a 

 seedling from seedlings raised through several generations. It belongs 

 to the Green Mountain group. The vines are large, strong, healthy, 

 and well branched. The flowers are white and abundant, but rarely 

 producing seeds. The abundant tubers are large, broadly roundish, 

 with rather shallow eyes, creamy white skin, and white flesh of very 

 fine quality." (Stuart.) 



55513. Manhattan. 



55514. Manhattan Black. This is a main-crop variety and may be culled 

 -improved Comptons Surprise." The vines are vigorous, with dark- 

 •^reen foliage; the tubers are nearly round, with dark-purple skin 

 and very solid white flesh of fine grain; in size medium to large.
