COLONEL MUNRO'S MONOGRAPH OF THE BAMBUSACE^. 17 



I have not seen any specimen of this ; and Ruprecht states that the specimen he saw- 

 was too young to have any of the genitalia perfect. If the lower flower has only one 

 palea, the plant would belong to Arthrostylidimn, from which, however, the tessellated 

 leaves would appear to keep it distinct.

 briatis, inter strias pubcscentibus, demum glabrescentibus ; panicula 2-3 poll, longa,

 gine apicem versus ciliata, sub lente scaberulo-hispida ; superior brevior, apice bimucronata, carinis 

 apices versus extus ciliatis. Squamula vix insequales, basi venosse, oblongse, obtusae, apice longe ciliatse. 

 Stylus vix ullus, cito in stigmata 3 divisus. Fructus matm-us linearis, sub 3 Un. longus, apice attenu- 

 atus, sulco longitudinali notatus. 



This species has very rarely been found in flower ; and when in foliage only it is 

 extremely difficult to distinguish it from Tliamnocalamus spathijiorus, Munr., Arun- 

 dinaria spathiflora, Trin. The best marks of distinction are the roughness of the stem 

 below the nodes, the long points to the leaves, and the membrane at the top of the 

 vagina and below the articulation of the petiole, which is only slightly haii-y. The leaves 

 have often long hairs below. 



4. A. KuuiLENSis, Ruprecht, in Bull. Petersb. viii. (1850) 121. Panicula simplici 

 racemosa, 2-3 poll, longa, rhachi pubescente; foliis tessellatis, 10-11 lin. latis; vaginis 

 efimbriatis. — Steudel. I. c. 335. 



Hab. Ins. Ouroup Kui'ilarum, s. v. Ruprecht.
