ARBORETUM NOTES. 41 
BIGNONIACE:. 
it flowered very scantily or hardly at all. This ane 
summer (1869) and several previous ones, it has | 
flowered so profusely as to be a magnificent object 
The flowers are beautiful as well in their general 
effe¢t as when separately and closely examined, 
their honey-like scent is very sweet and powerful, 
and they are frequented by innumerable bees and 
other inse&ts. The time of blossoming varies 
somewhat, according to the warmth or coldness 
of the season; I have known it to begin as early as 
July, and as late as the middle of September. 
It was in 1857, I believe, that the Catalpa first 
bore its pods at Barton, and since then it has 
produced them pretty regularly (except in 1861), 
but in very various degrees of abundance. Even 
in the most productive seasons, the number of 
pods is always very small, compared with that of 
flowers; the great majority of the panicles of 
flowers form no pods, and there seldom are more 
than one or two toa panicle. The pods are very 
curious; in the unripe state they give one the 
idea of very slender green candles or tapers 
hanging from the stalks; in a favourable season 
they hang on through a great part of the winter, 
and have a very singular appearance amidst the 
leafless twigs. 
Dr. Sims, in the Botanical Magazine (in 1808), 
says, ‘“We have never known it to produce 
pseeds.”’
