segments of the calyx, of an orange ground, marked with numerous 
crimson-branched veins, when fully blown curving backwards. Sta- 
MENS numerous, monadelphous: anthers red, apparently one-celled. 
Styes eight, projecting beyond the stamens, stigmas capitate. 
PopuLarR AND GeEOGRAPHICAL Notice. This very handsome 
plant is a native of the southern part {of Brazil, and appears to have 
rather an extensive range, as it has been met with both on the Organ 
Mountains, by Mr. Gardner, and the Rio Negro in the Banda Oriental, 
by Mr. Tweedie. It approximates in character to the Abutilon elegans 
of the Plantes Usuelles de Brasil. of Auguste St. Hilaire, but differs in 
habit from most other Abutilons. Our drawing having been made 
in very wet weather the flowers were imperfectly. expanded, as like 
most of its kindred it is very markedly influenced by the state of the 
atmosphere, particularly of the light. The genus Sida, from which 
Abutilon has been separated, comprises, if we include Bastardia, Gaya, 
and Abutilon (as is still done by Decandolle and others) about 200 
species, many of which are accustomed to unfold their flowers at such 
stated hours that Bory de St. Vincent asserts, that from the single 
genus Sida, a Dial of Flowers (Horologium Flore) might be con- 
structed, so accurate, that between the tropics the hour of the day 
might be ascertained by means of it. The leaves of some of the spe- 
cies exhibit perceptible changes of position, those, for example, of the 
Sida Abutilon (Linneus) fall close to the stem, and seem to protect it 
against the night air. A similar action may be observed even during 
the day, in the large leaves of the Hedysarum (Desmodium) gyrans; 
for, should dark clouds suddenly overspread the sky, they will imme- 
diately fall down and cover the stem as with a mantle. 
INTRODUCTION; WHERE GROWN; CuLTuRE. Introduced about 
two years ago into the Glasgow Botanic Garden, most likely by seeds 
from Mr. Tweedie. Our drawing was made in the month of March 
Jast, from a plant in the possession of Miss Trail, of Hayes Place, 
Kent, to whose extreme courtesy we are indebted for the opportunity 
of figuring it. It requires the greenhouse only, and is of the easiest 
culture, growing very freely, and being constantly covered with its 
elegant flowers during the greater part of the year.
