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. umbraciilifera (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^MONOROPS. — 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 Caia??ius. 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 

 I Sin. 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. mela7tochcetes^ 

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

 pinnate leaves and spiny petioles. D. Jenkinsianus (^Calamus 

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

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

 which reach loin. or i2in., are of a beautiful dark green; the 

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

 spines. D. Leivisia7uis {Calamus Lewisiamis) is unfortunately 

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

 and pinnate leaves, varying from 2ft. to 6ft. long ; the pinn« 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. melajiochcefes {Calamus melanoclu^fes) 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. pale7nba?iicus {Calamus palpjnbanicus) 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.
