 tubum aequantia, 2.5 mm. longa; corolla succinea ("amber yellow" ex 

 Ridgway, Color Stand, pi. xvi. 21'b), tubo lato 5 mm. longo intus striis 

 12 aurantiacis notato, lobis late oblongis 11-12 mm. longis 5-6 mm. latis 

 apice rotundatis vel leviter truncatis; stamina in planta visa microstyla

Plants raised from seed collected by E. H. Wilson in Korea in 1917 

 flowered this spring for the first time in this Arboretum. As the flowers 

 have not been described, a description drawn up from the living material 

 is here given. Forsythia ovata appears to be a very distinct species; even 

 in its winter state it is easily distinguished from the other species by the 

 pale yellow color of the young branchlets and by the light gray bark of 

 the older branchlets which become slightly corky and split by longitudinal 



fissures. 



Viburnum corymbosum Rehder in Jour. Arnold Arb. in. 214 (December 

 28, 1922) is antedated by V. corymbosum Urban in Fedde, Rep. Spec. Nov. 

 xvin. 121 (August 15, 1922). When I published this new combination 

 based on Cassine corymbosa Mill., the August number of Fedde's Reper- 

 torium had not yet reached the Arboretum library and I therefore was not 

 aware of the existence of the older homonym. I consider it, however, 

 rather fortunate that the publication of Urban's V. corymbosum makes it 

 possible to retain the well-known name V. obovatum Walt, for the species 

 in question, for the two other older names enumerated by me (1. c.) are 

 non-valid names and cannot replace Walter's name. The first of these 

 names, Cassine peragua of 1753 (1. c. 213, footnote 3) is a homonym of his 

 earlier and valid Cassine peragua of 1753 (1. c. 213, footnote 3) and Cassine 

 caroliniana Lamarck is not valid, because it is a synonym of the earlier 

 and valid Cassine corymbosa Miller which, however, as already stated 

 cannot be transferred to the genus Viburnum, on account of V. corymbosum 

 Urb.
