DoDECANDRIA. MONOGYNIA. 
CALYCIFLOR2. LYTHRACES. 
LYTHRUM. (Purple Loosz-stRIFE.) 
Generic Character. Calyz below the fruit, tubular, with twelve 
teeth, alternately smaller. Petals six, fixed on the calyx. Sta- 
mens twelve, six shorter than the others. 
LyrHrum saticarta. Spiked purple Loose-strife. A 
very handsome plant when in flower, and sure to attract 
attention by its long spike of beautiful purple flowers, peeping 
above the Reeds and Rushes of the watery and marshy 
places where it grows. The stem is often three feet high, 
the leaves opposite, long, heart-shaped at the base, and 
growing mixed with the flowers, as well as at the lower part. 
I have found it in Surrey with the spike of flowers more 
than a quarter of a yard long. There is a small species, also, 
L. nyssoprrotium, Hyssop-leaved Loose-strife, growing in 
moist places in the east of England, not above six inches 
high, with small flowers.
