a new species of Blepharis. All these genera exist in India, and none of them 
have yet been found in America. 
CONVOLVULACE. The herbarium of Professor Smith contains 
twenty-two species of this order, among which however there is no plant that 
presents any thing remarkable in its structure ; the far greater part belonging 
to Ipomea, the rest to Convolvulus. 
In the herbarium there is a single species of Hydrolea, nearly related to 
Sagonea palustris of Aublet, which would also be referred to this order by 
M. de Jussieu. But Hydrolea* appears, to me, to constitute, together with 
Nama, a distinct family (4Zydrolew) more nearly approaching to* Polemoniacez 
than to Convolvulaceze. 
SCROPHULARIN. The collection contains only ten plants of this 
family, of which two form new genera, whose characters depend chiefly on the 
structure of antherze and form of corolla. 
The LABIA'T£ of the herbarium consist of seven species, three of which 
belong to Ocymum, a genus common to equinoctial Asia and Africa, but not 
extending to America; an equal number to Hyptis, which is chiefly American, 
and has not been observed in India: the seventh is a species of Hoslundia, a 
genus hitherto found only on the west coast of Africa, and which in its 
infloreseence and in the verticillate leaves of one of its species, approaches to 
the following order. 
VERBENACE4, together with Labiatz form one natural class,+ for the 
two orders of which it has already become difficult to find distinguishing 
characters. 
In the Congo herbarium there are seven Verbenacez, consisting of three 
beautiful species of Clerodendron; two new species of Vitex ; Stachytarpheta 
indica of Vahl; and a new species of Lippia, which, from its habit and 
structure, confirms the union of Zapania with that genus, suggested by 
M. Richard.| 'This species from the Congo has its leaves in threes, and has 
nearly the same fragrance as Verbena triphylla, whose affinity to Lippia,
