 Numerous specimens received lately from the Department of Agri- 

 culture at Washington from trees cultivated at Mr. David Fairchild's 

 place "In the Woods/' Chevey Chase, Maryland, and at Chico, Cali- 

 fornia show at the first glance a marked difference in the pubescence of 

 the leaves; in some the leaves are pubescent on both sides, while in the 

 others they are quite or nearly glabrous except near the base of the mid- 

 rib beneath and at the same time are generally narrower, inclined to be 

 broad-cuneate at base, and their color is more grayish green as compared 

 with the distinctly yellowish green color of the pubescent form. The 

 latter should be considered the typical form of the species, as Siebold & 

 Zuccarini describe the leaves as "novella utrinque, adulta praesertim 

 subtus pilis rigidis venis impositis pubescenti-scabra et saepius ibidem in 

 inferiore nervi medii parte lana brevi (sicca) fuscescente barbata," though 

 in the diagnosis of the species he says "foliis . . . glabris vel praesertim 

 subtus pubescenti-scabris." In the flowers and in the fruit there is ap- 

 parently no difference between the two varieties. The glabrous form 

 seems to be widely distributed in China, as appears from the enumera- 

 tion of specimens above, while of the pubescent form I have seen only 

 one specimen from north Kiangsu, collected by Joseph Hers near Siao 

 Hsien, May 28, 1919 (No. 1046) and two from Honan, collected by L. 

 H. Bailey on Chikungshan, June 14 and 30, 1917. The only Formosan 

 specimen I have seen (E. H. Wilson, No. 10010) differs from the Chinese 

 glabrous variety in the narrower more caudately acuminate leaves and 



may be a different form. 



Besides this variety and the type (Primus mume a typica Maximowicz 

 in Bull. Acad. Sci. St. Petersb. xxix. 84 (1883); in Mel. Biol. xi. 672 

 (1883).— P. Myrobalana fl. roseis Hort. gall, ex Kew Hand-list i, 

 (1894) several varieties and forms are in cultivation, as P. mume var. 

 albo-plena Bailey, var. pendula Nichols., var. pleiocarpa Maxim., var. 

 Goethartiana Koehne, var. bungo Makino, and Armeniaca mume var. 

 alba and var. Alphandi Carri&re. Armeniaca mume var. alba Carriere 

 may possibly be the same as var. tonsa described above, but as Carriere 

 does not say anything about the pubescence or lack of pubescence of this
