Rehder, in his monograph of Lonicera (l.c.), classifies 
the 154 species known to him in two sub-genera, viz. :— 
Chamecerasus, in which the 2-flowered, usually peduncled 
cymes are borne in the axils of the leaves, which are 
never connate; and Perielymenwm, in which the 3- 
flowered, sessile cymes are arranged in spikes or whorls 
at the ends of the branches and the bases of the upper 
leaves are usually connate. Of the 131 species of 
Chamecerasus, eight constitute a well-marked section, 
which Rehder has named Jsoxylostewm, to which L. syrin- 
gantha belongs. Unlike most species of Lonicera, those 
belonging to this section have the corolla perfectly 
regular, with a comparatively short, straight tube. ‘Two 
such species have already been figured in this work, 
namely: L. tomentella, Hook. f. & Thoms. (t- 6486), and L. 
‘Alberti, Regel (t. 7394) ; the latter Rehder regards as a 
variety of L. spinosa, Jacquem. Both of them differ from 
DeceMBER Ist, 1904.
