History, Use, Propagation, Culture, 
be thinned in November, leaving not more than eight or ten plants in each pot ; and at the same time, tho 
pots beii}g sunk about three or four inches in some old tan or coal ashes, should be covered with a frame, which it 
is best to place fronting the west : for then the lights may be left open in the evening, to catch the sun whenever 
it sets clear. The third, or spring crop, should be sown in pots, not later than the twenty-fifth of February ; 
these must be placed in a frame, on a gentle heat, and as the heat declines the pots must be let down three or 
four inches into the dung-bed, which will keep the roots moist, and prevent their leaves turning brown, from 
the heat of the sun, in April and May. The plants thus obtained, will be in perfection by the end of May, 
and be ready to succeed those raised by the autumnal sowing. {Rishon in Hart. Trans, ii. 372.) 
R. odorata frutescens, if left to itself, hardly appears a distinct variety, but trained against a wall or to a stick 
it, and also the common mignonette, may be made to assume afrutescent character. According to Sabine, the 
tree mignonette is to be propagated from seeds sown in spring ; it may also be increased by cuttings, which 
will readily strike. The young plants should be put singly into small pots, and brought forward by heat, that 
of a gentle hot-bed being preferable, but they will grow well without artificial heat. As they advance, they 
must be tied to a stick ; taking care to prevent the growth of the smaller side shoots, by pinching them off, 
but allowing the leaves of the main stem to remain on for a time to support and strengthen it. When they 
have attained the height of about ten inches or more, according to the fancy of the cultivator, the shoots 
must be suffered to extend themselves from the top, but must be occasionally stopped at the ends, to force 
them to form a bushy head, which by the autumn will be eight or nine inches in diameter, and covered with 
bloom. Whilst the plants are attaining their proper size, they should be shifted progressively into larger pots, 
and may ultimately be left in those of about six inches in diameter at top. {Hort. Trans, iii. 181.) 
Mr. Lindley's theory of the nature of the inflorescence of this genus being remarkable, and only explained 
in his Collectanea Botanica, which is in few hands, it is here transcribed entire. " The usual idea of the flower 
of Reseda has been, that it is furnished with a calyx of a variable number of divisions, with as many petals, 
producing from their surface certain anomalous appendages, and with an ovary and stamens inserted on a 
great fleshy body, called nectary by Linnaean botanists, squama by others, and raised to the rank of a distinct 
organ by M. Mirbel, under the name of Gynophore. To us, however, it has always appeared, that this could 
by no means be the real structure of the plant, and that by a slight alteration of terms it not only might be 
much more satisfactorily explained, but its real affinity ascertained with some degree of probability. For 
even allowing for a moment an analogy between the nectary of this plant and the discus of others, particu- 
larly of some Tiliaceae, there is still a great diflSculty remaining to be overcome in the anomalous structure of 
the supposed petals, of which we can imagine no probable explanation. We are therefore of opinion, that 
a much more natural mode of understanding Reseda is to consider it as having compound flowers ; taking the 
calyx of authors for an involucrum, their petals for neutral florets, and their nectary for the calyx of a fertile
