 irregularly toothed on the upper, acuminate. Inflorescence very large, 

 pendulous, up to 2 m in length, the peduncles curved, 10 cm in diameter, 

 the spathes large, the first up to 40 cm long, the largest 1 m in length. 

 Spikes very numerdus, furfuraceons, 80 to 150 cm long. Male flowers 2 

 cm in diameter. Petals oblong-ovate, dull-purplish and yellow, 10 to 11 

 mm long. Stamens about 40. 



Occasionally cultivated, fl. continuously, from the upper axils first, 

 until exhausted, when the tree dies. Java; 



4. CALAMUS Linnaeus 



Spiny, slender, climbing, rarely erect palms, the leaves, sheaths, or 

 inflorescences bearing long, slender, retrorsely armed flagellaet Leaves 

 alternate, pinnate, the leaflets entire, acuminate, the sheaths spiny, produced 

 into a ligule or ochrea. Inflorescence axillary, usually elongated, branc|ied. 

 Spathes tubular or open, persistent, sheathing the peduncle and branches 

 of the inflorescence, close or distant, pa'tesing into bracts and bracteoles. 

 Flowers small, polygamo-dioecious, in distichous often scorpoid spikes. 

 Male flowers with a cupular 3-toothed calyx. Petals 3, acute, valvate. 

 Stamens 6. Female flowers with a calyx as in the inales. Corolla tubular 

 below, 3-fid. Staminodes forming a cup. Fruit globose to ovoid, 1-seeded,, 

 covered with appressed, imbricated, spirally arranged scales. (Grgek 

 "reed.") 



Species about 175, tropical Asia to Australia, few in tropical Africa, 

 about 35 in the Philippines. 



1. C. mollis Blanco. Uay (Tag.) ; Bejuco (Sp.-FiL) ; Rattan. 



A climbing slender palm 2 to 3 to many meters in length, the stems 10- to 

 12 mm in diameter, the younger parts armed with sharp slender spines. 

 Leaves about 80 cm long, the rachis not produced, armed beneath with 

 short, curved spines; leaflets linear-lanceolate, acuminate, 20 to 30 cm long, 

 margins with short, slender, spiny teeth. Inflorescence leaf-opposed, the 

 rachis slender, armed with reflexed spines, up to 1.5 m in length, the tip 

 produced as a long armed flagella. Partial inflorescences, few, remote, 6 to 

 15 cm long. Flowers yellow, fragrant; the males about 3 mm long, crowded 

 in distichous, straight or curved, linear-oblong, 1 to 2.5 cm lon^ spikes, 9 

 to 15 to each partial inflorescence. Fruits many, ellipsoid, apiculate, 

 about 1 cm long. (PI. Filip, pi. 99.) 



In thickets, Pasay, occasional, fl. most of the year; widely distributed in 

 the Philippines. Endemic. 



Young plants of some other species of this genus are commonly cultivated 

 in Manila for ornamental purposes; one of the most common being C. dis- 

 color Mart., the leaves white on the lower surface. 



5. NIPA Wurmb 



A gregarious palm of brackish swamps, from stout, branched rootstocks. 

 Leaves elongated, pinnate; leaflets lanceolate, entire. Inflorescence erect, 

 from the rootstock, the male with many, brown, imbricate sheaths (spathes) , 

 the male flowers small, mixed with slender bracteoles, in catkin-like lateral 

 branches of the spadix. Sepals linear, the tips broad, inflexed. Petals
