gen. amer, 3. p. 393. Corolla violaceous. 
Caraccas Rachicallis. Shrub 8 feet. 
Cult. Elegant shrubby plants of difficult culture. A mix- 
ture of peat and sand will probably be the best soil for them, 
and they should be grown in pots half filled with pot-sherds. 
They may either be increased by seeds or by cuttings planted 
in sand, with a bell-glass over them. They should be placed 
on shelves in a green-house. 
LXXXIII. LU'CYA (named by De Candolle after the late 
Lucy Dunal, who made many observations upon the Rubiaceous 
plants growing in the neighbourhood of Montpelier, as may be 
seen by comparing the fl. fr. ed. 3. vol. 5. p. 499., sister to 
Michel Felix Dunal, professor of botany at Montpelier). D. C.

lobes obtuse. Stamens shorter than the corolla. Style short, 
bifid. Capsule globose, didymous, 2-celled, with a loculicidal

and tuberous. Stems short, glabrous. Leaves almost sessile, 
cordate-ovate, downy beneath: upper ones usually by fours. 
Flowers axillary, and nearly terminal, solitary on very short 
pedicels, small, white.
