discolored." Shortly after its introduction into the U.S. by C.S. 

 Sargent, the plant was sent from the Arnold Arb. to Andorra Nurs. = 

 f. microphylla. 



f. microphylla Rehder (A. Rehder, Mitt. Deut. Gesel. 17:160. 1908, as 

 forma nova) - differs in part from the type [of /. crenata] in that it is 

 dense, robust, low growing, lvs. 0.8- 1.2 cm long, 0.3-0.6 cm wide, 

 ovate-elliptic or narrowly elliptic, mucronate tipped, margin crenate- 

 serrulate; fr. 6-7 mm in diam.; very frost hardy; grown in Arnold Arb. 

 from seed coll. in Metake, Hokkaido, Japan, by C.S. Sargent 1892. 

 Rehder chose to cite the Maximowicz var. name presumably from the 

 Matsumura reference when changing the rank from var. to forma and 

 adding a description based on Sargent's sdlgs. No other reference to or 

 by Maximowicz other than Matsumura (see var. microphylla 

 Maximowicz) could be found to this name (still cannot be found!). As 

 discussed under var. microphylla, Rehder reluctantly used the var. name 

 of Maximowicz for his new forma even though it was without a 

 description. However, since he erected a new forma with a description of 

 a new plant it was not merely a change in rank. Therefore "Maximowicz 

 ex Matsumura" is not part of the author citation of f. microphylla. S.-y. 

 Hu, Jour. Arnold Arb. 30:323. 1949 - described Rehder's f. microphylla 

 [= Sargent's introductions] as native to Japan and Korea, as a dwarf, 

 which does not fit Andorra's comments. Rehder did not comment on 

 dwarfness. The fact that Hu (1949) associated f. microphylla with 

 dwarfness may explain why she listed the dwarf plants GLASS and 

 MORRIS DWARF as cultivars of f. microphylla and listed 

 MICROPHYLLA, a low-growing plant, as a cultivar of var. longifolia 

 f. rehderiana. S.-y. Hu, Amer. Hort. Mag. 49(4): 199. 1970 - again cited 

 f. microphylla as a wild dwarf form, but this time she listed 

 MICROPHYLLA as a cultivar of f . microphylla. While f. microphylla 

 may or may not be dwarf, it is considered as an authentic botanical forma 

 and not a synonym of MICROPHYLLA as accepted by other authors. 

 See MICROPHYLLA, var. microphylla. 



MICROPHYLLA (Angelica Nurs., Kennedyville, Maryland, cat. p. 36. fall 

 1974-sp. 75) - upright; lvs. glossy; extremely hardy; our sel. This is a 

 different clone from all other MICROPHYLLA in this checklist. 

 Illegitimate, since the name is in Latin form. 



MICROPHYLLA (S.-y. Hu, Nat'l Hort. Mag. 36(1):64. 1957, as a clone of 

 var. longifolia f. rehderiana) - low compact; lvs. small, shiny, elliptic, 

 acute at both ends, l/3"-7/8" long, l/5"-3/8" wide, 3-4 minute teeth on 

 each side. Idem, Amer. Hort. Mag. 49(4): 199. 1970 - listed as a cultivar 

 off. microphylla. B. Boom, Nederl. Dendr., p. 323. 1959 - lvs. 1-1.5 cm 

 long, smaller than LATIFOLIA and ROTUNDIFOLIA lvs., narrowly 

 oval, entire margin is crenate; introd. 1868 to Netherlands by Siebold 

 with var. microphylla Maximowicz in syn. L. Chadwick, Amer. 

 Nurseryman 98(12):23. 1953 - 4-7 ft tall, upright in smaller sizes, stiffly
