Southern Hudsonia. Shrub 1 foot. 
Cult. Hudsonia is a genus of pretty little shrubs, with the 
appearance of heath, which are rather difficult to cultivate : they 
thrive best in peat soil, in a shady situation, and should be pro- 
tected under glass during winter, for this purpose they had 
better be grown in pots. They may be either increased by 
layers, or ripened cuttings planted in sand under a hand-glass.

N. B. Léchea Chinénsis of Lour. is a species of Commelina. 
Cult. Lèchea is a genus of small herbaceous perennial plants, 
which succeed best when grown in small pots planted in a mix-

creased by seeds or by cuttings planted in sand under a hand- 
glass.

Calyx of 5 permanent sepals, equal (f. 65. a. f. 66. c.) or un- 
equal, (f. 64.c. f. 62. a.) usually with membranous margins, free or 
connected at the base, imbricate in the bud; and therefore they 
are disposed in a double series, as in Tribe Vidlee, 3 in the outer 
series, and 2 in the inner. Petals 5, alternating with the sepals 
(f. 65. b.) hypogynous, inserted in the thalamus, usually mar- 
cescent, and obliquely convolute in the bud, sometimes equal (f. 
66. b. f. 65. b.) sometimes unequal (f. 62. c. f. 63. c.), but when 
they are unequal the lower one is in the form of a labellum (f.64. c.) 
furnished with a spur or hollow at its base (f. 64. b. f. 63. c+). 
Sometimes there is a staminiferous urceolus and sometimes fili- 
form appendages between the petals and the stamens. Stamens 
5, inserted in the thalamus or calyx, alternating with the petals 5 
anthers 2-celled (f. 65.e.) opening inwards by 2 longitudin al 
chinks ; these are appressed to the ovary, usually free, but 
sometimes they are more or less connate at the base into. a mona- 
delphous disk; filaments usually dilated, sometimes from the base 
in this case, bearing the anthers at the very base (f. 64. d.), som e- 
times they are unguiculated at the base, but they are dilated 
at the top, and therefore bearing the anthers a little higher up 
at the tops of the claws (f. 66. a.), in either case the filaments ar? 
drawn out beyond the anthers into an arid membrane, more 
or less imbricately girding the style, rarely awl-shaped but 
never terminated by the anthers; two of which in the irregular 
flowers are usually drawn out downwards into a filiform ap”
