m, very abundant locally and the only species of the genus in the locality 

 according to the collectors. 



Prospectus of the varieties of Calamus dim orphacant hits: 



1. Ligule membranous, brittle, armed with few spinules, leaflets very narrow, 



bristly only on the mid-costa above, margins ciliated with spreading, spinuli- 

 form hairs. Fruit 8 to 10 mm long forma typica 



2. Ligule very long (as much as 15 cm) rigid, very densely armed with horizontal.. 



more or less seriate spines; leaflets very numerous, narrow, bearing above, 

 on the mid-costa, and on one nerve on each side of it, several .subspiny 

 bristles; margins ciliated with rather robust spreading spinules. 



var. montalbanictts. 



3. Ligule relatively short, bristly-spinnlous ; leailets very closely set, very stiff 



and thickish, narrowly lanceolate, furnished with conspicuous subspiny 

 bristles only on the mid-costa above, margins ciliated with spreading 

 spinules. Fruit larger than in type (13 mm long, 10 mm broad). 



var. zambaU nsis.

Scandens, mediocris, vaginis densissime spinis laminaribus, inaequa- 

 libus, creberrime plus mimisve seriatis ac basi confluentibue armata; 

 ligula rigide elongaia. densissime spinoso-hispida. Frondium petiolo 

 breviusculo (7-8 cm longo), spinis inaequalibus arm a to ; parte pinnifera 

 circiter 1 m longa; cirro valid issimo aculeis reduncis robustis semiver- 

 ticillatis armato; segmentis numerosis, aequidistantibus, ensiformibus, 20-

Scandent, of moderate size. Leaf -sheaths very densely armed with 

 very unequal, laminate, more or less closely seriate, confluent spines; 

 ligule rigid, 5 to 6 cm long, entirely covered, in one specimen, with very 

 rigid, needle-like spiculae of unequal length. Leaves with the petiole 

 armed with the same kind of unequal spines as in C. dimorphaemthus, 

 7 to 8 cm long, the pinniferous part apparently about 1 m in length, 

 terminated by a very robust, strongly clawed cirrus: leaflets numerous, 

 equidistant, ensiform. or very narrowly lanceolate, 20 to 25 cm long, 13 

 to 15 mm broad, smooth underneath, sprinkled above on the mid-costa 

 and on one nerve on each side of it, with not very rigid bristles; margins 

 rather closely and appressedly spinulous. Fruiting spadix about 30 cm 

 long, with smooth spathes, and very few, small, slightly branched, partial 

 inflorescences, of which the lowest are only 5 cm in length and have 

 very few spikelets. Fruit ovoid or subobovoid, obtusely beaked. 17 mm
