Chanoine Béguin, of Brignoles, in March, 1899, under the name 
of A. Simonis. 
A. Regine. 
A garden name for a very distinct species with small glaucous 
rough leaves; may possibly be A. megalacantha Hemsley. The 
plant was received from Mr. M. Herb, Naples, in January, 1901. 
A. rigida Hort. 
As Prof. Trelease has shown,” the true- A. vigida Mill. is not 
known to exist anywhere in cultivation. The plants generally 
called A. rigida in gardens are A. elongata. 
A, Rovelliana. 
Under this name a small Agave is cultivated, which has the 
leaves mottled like those of A. Terraccianot. I could not ascer- 
tain where Todaro has described it, although the species is attri- 
buted to him in the “ List of Seeds of the Palermo Botanic Garden.” 
A. Salmiana. 
Though somewhat variable, this plant is generally larger than 
A. atrovirens, and always recognisable by its ashy-grey leaves, 
which are generally few in a rosette, and very thick and broad at 
their base; the end-spine is stouter than in A. atrovirens. We 
have several forms and a narrow-leaved variety. A. Salmiana 
and A. atrovirens are much cultivated in Mexico for “ pulque.” 
A. Sartore. 
We are indebted for this plant to Prof. A. Borzi, Director of 
the Palermo Botanic Garden. A plant purchased from Messrs. 
Haage & Schmidt as A. sp. from Paso del Macho proved to be 
the same species. 
A. Schlechtendalit. 
I identified this species with the help of Jacobi’s original 
photograph. It is by no means a form or variety of A. atrovirens, 
but a very distinct species. It is slow growing, with very glau- 
cous leaves. 
A. schidigera. 
Though closely allied to A. filifera, this is without doubt 
specifically distinct. It never produces offsets, but always dies 
after flowering. 
A. Schotti. 
Introduced at La Mortola by Mr. C. A. Purpus from Mexico, 
in 1905. This throws out suckers freely. 
A. Scolymus. 
Under this name several closely allied plants are grown here. 
wae them, which approaches the type very closely, flowered in
