Roxburgh's description gives the number of leaflets as " thirty- 

 four pairs," which has puzzled most botanists. It is obviously a mis- 

 take for 3 to 4 pairs, as can be seen by reference to his type in the 

 British Museum, which is undoubtedly this common plant. Blumo 

 makes two varieties and Beccari 5 more and many more might be 

 made, as the plant is very variable. The number of leaflets varies 

 apparently with age of the plant, as well as with the locality. The 

 Singapore form much resembles Blume's var. tetrastichus. The most 

 distinct variety here is the pretty mountain form purpurasccns. It 

 is more compact with very reddish colored leaves, and a crimson raehis 

 to the inflorescence. 



2. C. PENANGENSIS, Ridl. Stem slender, as thick at top as a 

 goose-quill, sheaths striate, armed with scattered short thorns pointing 

 upwards; petiole very short 1 inch long; raehis thickly armed with 

 numerous short recurved thorns, solitary or in pairs, leaflets about six, 

 two terminal connate at the base, distant lanceolate acuminate with a 

 lew rather strong, black bristles at the tip, margins thickened nerves 

 six, transverse nervulos elevated, conspicuous when dry. Spadix male 

 18 inches slender, spathes narrow armed with scattered black tipped 

 hooks. Branches about four, 6 inches long, spikes distant an inch long 

 alternate, spathels smooth unarmed. Flowers rather distant small. 

 Calyx ribbed, campanulate. Flagellum very slender. 



Penang : West Hill (Curtis 2268). This plant is perhaps the spe- 

 cies intended by Beccari, by C. Martian/US Becc. Fl. Brit. India VI. 

 459. This was based on a plant collected by Gaudicliaud in Penang. 

 Martius confused it with Roxburgh's C, peneillaUts, and published a 



description under that name composed of notes about Gaudichaud's 

 plant with some of Roxburgh"s description of C. pcncillatus added,
