many Coffeacee ; and where there are eight, ten, or more, apparent 
leaves, three, four, or more, on each side of the true ones must be con- 
sidered as stipulary processes, similar to the sete of Hedyotidex and 
Spermacocee. The few cases where the number of leaves in the 
whorl of a Galium is uneven, are probably due to accidental abortion, 
as they are very inconstant, not only in the same species, but in the 
same plant. 
As to Caprifoliacer, they are certainly closely allied to Rubiacee, 
and perhaps in this case, as in that of many of the most Natural Or- 
ders, a precise artificial line would be difficult to draw, but indepen- 
dently of the almost constant absence of stipules, there is on the one 
hand (as observed by Lindley) an approach in habit and structure to 
Saxifragacee, and in another point of view, the ordinary carpellary 
number of Caprifoliacez is three, and that of Rubiacee but two. G. B. 
InTRopUCTION; WHERE Grown; CuLrurE. The first introduc- 
tion of Crusea rubra into European gardens was about the year 1797, 
when it was cultivated in the Botanic Garden of Schoenbrunn, where 
the elder Jacquin figured it in the third yolume of his Hortus Schoen- 
not have less than 300 heads of flowers such as those in the figure. 
The plant grows freely in sandy loam with a little peat, it flowered in 
great perfection in a dry part of the stove; seeds freely, and strikes 
from cuttings. The habit of the plant in summer, with its beautiful 
foliage and yery curiously armed stem, is highly attractive. Itis a valu- 
able ornament, as it comes into flower in rich profusion at a time when 
the stove is rather barren of flowering plants.” 
Derivation or THE Names. 
CrusEa, in honour of Dr. Cruse of Keenigsberg, author of a dissertation on 
ubiacex, in which he first indicated the present genus. Rvsra, red 
from the red colour of the flowers.
