A plant of Lonicera subsessilis raised from seed collected by E. H. 

 Wilson in Korea and received in 1917 flowered this year early in June 

 for the first time in this Arboretum, affording the opportunity to complete 

 the description of this species of which the flowers were before unknown. 

 The species belongs to the division of the subsection Rhodanthae with 

 connate ovaries and red fruit in which L. conjugialis Kellogg, L. Tatari- 

 novii Maxim., L. M aximowiczii Reg., L. Chamusoi Bge. and L. Graebneri 

 Rehd. belong and is most closely related to t lie last which has short 

 peduncles and apparently pale-colored flowers, while the others have long 

 and slender peduncles and dark-colored flow^ers, but L. Graebneri is easily 

 distinguished by its pubescent leaves, longer peduncles, longer subulate 

 pilose bracts, setosely ciliate bractlets and longer setosely ciliate sepals. 

 A remarkable feature of this species will be its tetramerous flowers if this 

 turns out to be a specific character and not an abnormal state; the fact that 

 not only in the one shrub which flowered here all flowers without exception 

 showed a 3-lobed upper lip and 4 stamens but that also in the type speci- 

 men the young fruits show only 4 calyx-lobes, as far as the latter have not 

 fallen off, would indicate that the tetramerous flowers are a specific char- 

 acter. The only other species of the genus which has occasionally tetra- 

 merous flowers is L. angustifolia Wall, of the subgenus Isoxylosteum. 



X Lonicera Purpusii (L. fragrantissima X Standishii), hybr. nov. 



Upright shrub: branchlets glabrous, or particularly the longer vigorous 



shoots, loosely setose-pilose with reflexed hairs, the young shoots not 



bloomy; leaves elliptic-ovate or ovate to narrow-elliptic or oblong-ovate, 



5-8 cm. long, and 2.5-4 cm. broad, acute to acuminate and mucronate, 



rounded to broadly cuneate at the base or sometimes the lower ones 



slightly subcordate, dark green and glabrous above, light green and retic- 



ulately veined beneath, and setose-pilose on the midrib and sparingly so 



on the lateral veins and veinlets or, particularly on the flower-bearing 



branchlets, nearly glabrous; petioles setose to nearly glabrous. Flowers 



very similar to those of L. fragrantissima, glabrous except some hairs on 



the margin of the bracts. 



Specimens examined: Botanic Garden, Darmstadt, Germany, A. Purpus 

 1920 and 1921 (flowers and mature leaves). 



This hybrid originated spontaneously some years ago in the Botanic 

 Garden at Darmstadt from seed of one of the parents. In its leaves it is
