COLONEL MUNRO'S MONOGRAPH OF THE BAMBUSACEJ2, 17 



I have not seen any specimen of this ; and Kuprecht 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 Arthrostylidium, from which, however, the tessellated 

 leaves would appear to keep it distinct. 



3. A. uaceuosa, Munro. Culmi internodiis apice scahris; foliis tessellatis; vaginis fmi- 



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

 rhachi glabra, spiculis subpollicaribus, 4-5-floris.

Culmus teres, 2-1-pedalis, pallide cseruleus, internodiis ssepe vix bipollicaribus, apice scabris vel scabriuscnlis,

 petiolum brevem attenuata, 4-6 lin. lata, 2-4- poll, longa, apice setaceo acuminata, nervis secundaria 

 utrinque 3, venulis transversis supra subtusque conspicuis; juniora subtus pilis longis hirsuta, 

 demum glabra. Vagina striata, inter strias primum pubescentes, demum glabrae, membrana brevi 



ciliatula terminate, ligulatae, oreque ciliis paucis longis fimbriate. Panicula simplex, rhachi glabra 

 in ramulis terminalibus longe exserta; spiculis 8-4 j pedicellis angulatis, 1— 1| poll, longis. SpicuUe 

 glabra3 vel hirsutiuscute, 4-5-florae, intra glumas pcdicellatae, subpollicares ; rhachillaj articulis 

 hirsutis flosculis fere aequilongis. Gluma valde variabiles, plerumque breves vel brevissimse, obtuwe 

 vel acuta, inferior ssepe fere obsoleta. Palea inferior caudato-acuminata sub 9-11-nervis, fusca, mar- 

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

 apices versus extus ciliatis. Squamula vix inaequales, basi venosae, oblongae, obtusa, apice longe ciliata. 

 Stylus vix ullus, cito in stigmata 3 divisus. Fructus maturus linearis, sub 3 lin. 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 Thamnocalamus spathijlorus, 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 hairy. The leaves 

 have often long hairs below.

efimbriatis. — Steudel. I. c. 335.
