along this coast. It has been regarded in all European Floras as 
the plant of which Linneus* says :—‘ Cortusus plantam primus 
in Europa habuit 1561, hodie ab ea sepes in Lusitania.” 
We have several variegated forms of it:—var. marginata, var. 
medio-picta, var. striata and under the name of A. Celsiana Hort. 
_ Ital. (not A. Celszi of Hooker!) a form with pale green margins. 
A. americana takes about fifteen years before arriving at the 
flowering period. 
A, angustifolia. 
Under this name a plant was brought to La Mortola 
from Mr. W. Wilson Saunders in June, 1868. Whether this 
is identical with what later on in the garden was called A. 
excelsa I do not know. These plants agree with the description 
and figures of A. angustifolia as given by Prof. Trelease,{ but do 
not usually produce bulbils with us. 
A, asperrima. 
The true A. asperrima is rather rare in gardens, A. marmorata 
being generally cultivated under its name. Our plants were given 
to us by Mr. A. Purpus, Botanic Garden, Darmstadt, having been 
collected by his brother near Viesca, in the State of Cohuahila, 
Mexico. In general aspect the plant resembles A. Salmiana, 
but it is smaller and the leaves are extremely rough on both 
sides. 
A. atrovirens. 
With this species is generally united the closely allied d. 
Salnuana. A. atrovirens has the leaves more contracted at the 
base and more acuminate, with a very long and slender terminal 
spine ; their colour is an almost shining dark green, very different 
from the ashy green or grey of A. Salmiana. We also grow a 
narrow-leaved variety, and a variegated form, A. atrovirens 
marginata. 
A, aurea. 
This species flowered in May—June, 1911, perhaps for the first 
time in Europe. The flowers are of a fine golden yellow. 
A. barbadensis. 
Was received from Prof. Trelease. It is “the Maypole,” 
“ Corate ” or ‘the Silk-grass”” of Barbados, where it is spon- 
taneous on the lee side and is planted in hedgerows from which 
it escapes. (Trelease im litt.) 
A. Beguni. 
This hybrid was given to us in March, 1899, by M. le Chanoine 
Béguin, of Brignoles (Var), who informs me that it was probably 
raised in the Pare de la Téte-d’Or in Lyon, and that it was 
named and distributed by M. Pierre Rébut, at Chazey-d’ Azerognes. 
The parents are not known. It belongs to the Lztiea section,
