to 30ft. in height; the petioles have all along their edges a 

 great number of small spines ; the leaves are deep green, fan- 

 shaped, and plaited. C. umbraculifera (Talipot Palm), with its 

 beautiful leaves, which are used in the same way as the species 

 previously described, is also a very slow grower, but reaches in 

 its native place sometimes over 100ft. high. The petioles are 

 protected at their edges by a quantity of small brown spines, 

 and the leaves, which are fairly large, are fan-shaped and 

 plaited, forming a circle about 12ft. across. 



D/EMONORops. — A genus closely allied to Calamus, under 

 which the species are often classified ; they are all very elegant 

 stove Palms, and their only distinction from Calamus exists 

 in the spikes, on which the flowers are scattered ; they 

 require the same treatment as Calamus. D. Draco (Calamus 

 Draco) is a rather distinct species and of a strong constitution, 

 and ought to be more largely grown ; the leaves are beautifully 

 arched and pinnate, varying from 4ft. to 6ft. in length ; the 

 pinnae are narrow, pendent, deep green, and vary from i2in. to 

 i8in. in length; the petioles are sheathing at their base, and are 

 protected with long black spines. D. hystrix (Calamus hystrix) 

 is a species possessing a very great similarity to C. melanochcetes, 

 but is undoubtedly more decorative ; it is very dwarf, with 

 pinnate leaves and spiny petioles. D. Jenkinsianus (Calamus 

 fenkinsianus) is a well-known species, with gracefully arched and 

 pinnate leaves, varying from 2ft. to 6ft. in length ; the pinnas, 

 which reach loin, or 12m., are of a beautiful dark green; the 

 petioles are sheathing at the base and protected with long, flat 

 spines. D. Lewisianus (Calamus Lewisianus) is unfortunately 

 rather rare ; it is characterised in its young state by its erect 

 and pinnate leaves, varying from 2ft. to 6ft. long ; the pinna? are 

 pendent, deep green, and vary from 6in. to i2in. ; the petioles 

 are white, with the exception of the base, which is of a blackish- 

 brown, and are extremely well protected with long black and 

 flat spines. D. melanochcetes (Calamus melanochcetes) is a distinct 

 and ornamental plant of a very dark green colour, producing 

 pinnate leaves with long, narrow, and pendent pinnae ; the 

 petioles are sheathing at the base and well protected by some 

 long and sharp spines, which are rather stout at the base. 

 D. palembanicus (Calamus palembanicus) is quite different from 

 the other species ; the - petioles are mostly erect, protected at their 

 back by some stout spines ; the leaves are pinnate, with narrow 

 drooping leaflets of a cinnamon-brown shade in their early state, 

 changing to deep green when fully developed. D. plumosus is an 

 elegant plant, producing some valuable plume-like, pinnate, dark 

 green leaves, varying from 2ft. to 5ft. in length; the pinnae 

 reach ift., and are very narrow; the petioles are also covered 

 with stout dark spines, which are whitish at the base. Very hand- 

 some for indoor or table decoration.
