and usually branching sete ; tube short, hairy; divisions of the limb 
rather longer than the tabie. linear, two rather shorter than the other 
wo. Tune of the corolla about half an inch long, slender, perfectly 
smooth, slightly dilated at the top, divisions four, oblong, spreading. 
Sramina inserted into the throat of the corolla and rather longer than 
its divisions; filaments slender, glabrous ; anthers oblong-linear, pur- 
plish. Sryie about the length of the stamens, often shorter, cleft 
at the top into two recurved divisions, lined on the inner side with the 
stigmatic surface.

Porutar AND GrocrapHicaL Notice. The small genus Cru- 
sea appears to be confined to the Mexican states, extending perhaps 
as far as the neighbouring island of Cuba, for the three Cape species 
lately added by Ernst Meyer from amongst Drége’s collection differ 
much in the calyx, corolla, and inflorescence, and evidently form a new 
genus. The present species and two other Cruseas from the same 
country, are perhaps the only plants among the numerous tribe of Sper- 
macocee worth cultivating, a tribe so generally remarkable for their 
weedy appearance, and which in the warmer parts of America and 
Asia, appear to take the place of our Galiums and Asperulas, but with 
a much coarser foliage and very small white or bluish flowers. The 
Cruseas, on the contrary, have all of them much larger flowers, of a 
pink or scarlet colour, especially the C. coccinea, which is perennial 
and has flowers nearly double the size of C. rubra, and which it would 
be highly desirable to introduce into this country. 
The Spermacocez form one of thirteen distinct tribes, constituting 
the very extensive and well marked Order of Rubiacex, originally 
proposed by the elder Jussieu, and retained in its full integrity by 
Chamisso and Schlechtendahl, Achille Richard, and Decandolle, all 
of whom, especially the author of the Prodromus, have illustrated the 
Order in detail. Lindley, however, in his Natural System, a work 
remarkable for the clear and concise manner in which the characters, 
affinities, and anomalies, of the Natural Orders are expounded, differs 
from all these authors in considering the Tribe of Stellate (including 
Rubia itself) as a distinct Order, and consequently changes the name 
of the remaining portion of the Order to that of Cinchonacee. But 
in this view, it is difficult to agree with him, great as his authority 
must be considered in most cases. The grounds of his opinion are 
thus stated in speaking of Stellate. ‘Usually a material dissimilari 
in habit, if accompanied by any clear character, whether of vegetation 
or fructification, is considered sufficient ground for the separation of 
a group of plants into two Orders ; in this case the weak angular stems 
cause a peculiarity of habit that cannot be mistaken, and the total 
absence of stipules, to say nothing of the didymous fruit, afford a cer- 
tain mark of recognition. Surely there is some inconsistency in sepa- 
rating, by the absence of stipules, Caprifoliacee which are indistin-
