Botanists more used to general classilication to suggest such modi- 
fications as may improve the groups which are now defective. 
In the first tribe, VerbascecB, I have followed Bartling, with some 
exceptions, and the addition of Calceolaria and Jovellana, which 
appear to me to connect Scrophularia with Alonsoa. It remains 
composed of the following genera : — 
Verbascum is a very natural European genus if taken in conjunction 
with Celsia, from which it is artificially separated by the presence of 
the fifth stamen. The German species have been well distributed 
by Reichenbach (FI. Germ. Excurs. 383) into three sections, Thap- 
suSy Lychnitis, and Blattaria, but the separation of the species is 
difficult. Roemer and Schultes enumerate 69 ; Reichenbach has 35 
German ones ; Tenore 24, in his Neapolitan floras ; Sprengel re- 
duces the whole to 49, and although his reductions are probably for 
the most part incorrect, yet the great extent to which the same spe- 
cies will vary in the texture and quantity of w'ool and the form of 
the leaves, and the great facility with which they produce hybrids 
(usually sterile), will probably induce the philosophical monographist 
to consider many of the published species as accidental states, hy- 
brids, or varieties, and reduce the number of legitimate species even 
below that admitted by Sprengel. 
Celsia includes several plants, differing more in habit from each 
other than from Verbascum and Alonsoa, but artificially distinct 
from both. It may be naturally divided into three sections, as 
follows : — • 
Sect. 1. Pseudothapsus. Herbse. Stamina 2 longiora glabra, an- 
theris oblongis adnatis, 2 breviora barbata, antheris medifixis bilocu- 
laribus loculis confluentibus. C. cretica, be tonicce folia, ^c. 
Sect. 2. A?-clurus. Herbas. Stamina 2 longiora glabra, breviora 
leviter barbata, antheris omnibus medifixis bilocularibus^loculis con- 
fluentibus. C. arcturus, coromandeliana. 
Sect. 3. Neffiea. Suffrutices. Filamenta omnia barbata. Antherae 
omnes terminales uniloculares, valvulis 2 ovatis acutis dehiscentes. 
C. parviflora, Decaisne, An genus proprium ? 
Alonsoa is so very different from Hemimeris in the structure of the 
flower, that one is surprised how they could ever have been joined. 
In habit it comes very near to Celsia (Arcturus), with which it is 
also connected by the structure of the corolla, &c. but besides some 
slight difference in the form and dehiscence of the capsule, Alonsoa 
has the flowers constantly resupinate by the twisting of the pedicel. 
The stamina (unlike ordinary cases of resupination) remain declinate 
in relation to the plant generally, thus becoming ascending with 
regard to the rest of the flower, whilst in Celsia they are declinate, 
both in regard to the plant and to the flower. 
Calceolaria, a very extensive genus, requiring as much as any 
the labours of a monographist, for the distribution of the species
