386 HORTUS MORTOLENSIS 
DRACENA. 
Of D. Draco we have one much-branched plant, which, 
however, has but a low stem, and shows little of the majestic 
character of the species. It occasionally flowers and fruits. 
Another specimen, which is just beginning to form a stem, was 
planted in the “Canarian” group in 1900; some fifteen other young 
plants were put in the same place in October, 1909. D. cinna- 
bart, which in habit resembles the former, but has shorter and 
stiffer leaves, was given to us by Prof. Balfour, of Edinburgh. 
D. Ombet was received from Palermo, having been collected by 
Dr, O. Beccari, in Nubia. 
ECHEVERIA. 
This genus was united with Cotyledon by Baker, Bentham 
and Hooker, and Schoenland. It is, however, well characterized by 
habit and geographical distribution (all the species are American), 
and in spite of some connecting links may always be readily 
recognized.* We are indebted to Drs. Britton and Rose, and to 
Mr. Purpus, of Darmstadt, for several of their new species. The 
genera Lenophylluwm, Oliverella, and Urbinia differ but little 
from it. 
ECHINOCACTUS. 
Most species of this genus do well; some have perished but will 
be replaced. A number of rare species were acquired from the 
late Mr. Harry Franck, of Frankfort-on-Main, in the autumn of 
1905. Thelarge H. Grusonii was bought from Mr. Berge, of Leip- 
zig, in October, 1897; it is now 40 em. high, and 1:50 m. in cireum- 
ference. For Chilian species we are indebted to Dr. J. Séhrens, 
Director of the Santiago Botanic Garden, and to Mr. E. Framm, 
of Hamburg; for species from Uruguay to Prof. Arechavaleta, 
Director of the National Museum at Montevideo, and for several ~ 
Mexican species to Mr. Weinberg, of New York. 
ECHINOCEREUS. 
This genus may well be retained as distinct from Cereus, with 
which it is often united. The flowers are invariably actino- 
morphous, the stamens always of equal length, and connivent round 
the style, thus closing the tube. In these points they differ 
essentially from the great majority of the species of Cereus. 
Other distinguishing characters are presented by the stigmata, 
the ovary, tube and fruit, and the general habit of the species. 
Ei. cinerascens and E. Ehrenbergii were bought from the Jardin 
d’Essai, Hamma, Algiers, in February, 1873. They now form 
large patches in the garden, flowering every year in great 
profusion.
