This species differs from the foregoing in the stem and branches being destitute of stalked glands, in 
the smaUer leaves with fewer nerves and less distinct serrature, and in the spikes being half the length of 
the leaves.

When I first established Astrcsa upon Croion lohafus, Linn., in the year 1841, 1 was only acquainted 
with eight species belonging to this genus ; since that time they have increased to not less than twenty- 
two. Specimens of all of them are preser^-ed in the Eoyal Herbarium at Berlm. _ ^ ,..„ ^ 
Among the plants sold by the Unio Itineraria, and coUected by Kotschy in I^ubia, on the hills of 
Cordofan, we find, mider no. 85, specimens labelled Crotm lohatu., totally different from the Limia^an species ; 
another distinct one, found on the west coast of Africa in several localities, is also figm-ed under the same 
name bv Palisot-Beauvois in the ' Plore d'Oware ct de Benin j' and though the real Croion lohatus, Lmn., is 
not onlv found in Mexico and in the West Indian Islands, but also in New Granada, Venezuela, Ecuador, 
and Brazil, I observed four other quite distinct species in diiferent sets of dried pknts sent to me for 
examination, all as nearly related to Cretan hiatus, Linn., as Astrea Seemunni. The geographical distribu- 
tion of the species oi Astrca appears to be very remarkable :-one species is fomid m ^ubia, another on 
the west coast of Africa, two species in Mexico, one in the West Indies, one in Central America, one m the 
West Indies and South America, and fifteen species in BrazU.
