COLONEL MUNRO'S MONOGRAPH OF THE BAMBUSACE^. 33 



Huh. In Himalaya, in montibus Kliasise, Moosmai-Cliurra, alt. 1000 p. s. m., Griffith, no. 558 ! ; Kala- 

 panec, alt. 4500 p. s. m., Hooker, no. 1107 ! v. s. 



Culmus " 10-15-pedalis, subcrectus, nutans," vix fistulosus, intcrnodiis glabcrrimis t-O ])oll. longis, 

 ramulis proliferis 5-9 poll, longis ad nodos glabros fasciculatis. Folia angusta, subsetaceo-acnminata, 

 basi attenuata, margine udo alterove brevissime serrata, concoloria, nervis secundariis utrinquc 3— l, 

 venulis transversis distantibus, vix elevatis, interdum segre discernendis. VayiruB striatse, usque ad 

 basin solutaj, glabrae, membrana brevissime ciliata tcrminatte, apice longe fimbriatse vol interdum 

 biauriculatse, ligula conspicua sat brevi. 



This approaches A.falcata and A. Khasiana in the form and size of the leaves, but it 

 is distinguished from both by the fringe at the top of the vaginae and the presence of 

 transverse veinlets on the lower surface of the leaves ; in this latter respect it approaches 

 A. Ilookeriana, of which, however, I can scarcely believe it to be a narrow-leaved state. 

 Griffith certainly mentions that he found it growing on the banks of the Moosmai water- 

 fall ; and it is well known that plants growing in such situations often assvime peculiar 

 forms.

II. Thamnocalamus. 



Falconer, MS. (nomen tantum) in herb. Hooker, et herb. Strachey. 



Spicule snrsiim imperfecta, l|-8-flora, in racemo simplici spatha vel bractea longissima involucrato, brevi- 

 pedicellata. Gliiina acuta;, paucinervia;, spiculis suis vix ^ breviores. Palea inferior acuta vel longe 

 acuminata, supremam vel sequans vel longe superans. Squaniula 3 fimbriatse. Stylus cito supra 

 basin trifidus. Caryopsis linearis vel lagenseformis. 



Cseteroquin quoad spiculas ut in Arundinaria. 



Gramina Himalayana, culmo plerumque tereti suffruticoso vel fere arboresccnte, nodis vix promiuidis. 

 Folia parva vel inconspicue vel conspicue tessellata, vaginis fimbriatis vel efimbriatis. Inflorescentia 

 panicula maxima decomposita laxa, ramis gracilibus longis multinodis, ramulis ultimis, ad nodos, 

 racemos 1-4 subsessiles, spatha ipsis multo longiore velatos, gerentibus. Interdum in T. Falconeri 

 racemi intra spatham basi muUibracteati, et rarissiine circa nodos ramorum dense fasciculati sunt. 



, The structure of the spicula in this genus is so very similar to that of Arundinaria, 

 tliat I should not have separated the two following species from that genus had I not 

 been joersuaded that so excellent a botanist as the late Dr. Palconer must have had good 

 reasons for separating the genus Thamnocalamus. Unfortunately I can find no defini- 

 tion of the genus by Dr. F., nor any specimen in flower of either species in his herba- 

 rium ; but, as I have already stated, it contains numerous specimens, in all stages of 

 growth, of Arundinaria falcata, which may therefore be the plant he intended as Tham- 

 nocalamus. It appears to me that this genus can only be well distinguished from 

 Arundinaria by its inflorescence, as described above. The spathes, which sometimes 

 have a foliaceous appendage, are remarkably persistent in T. spathijlorus, but much 

 sooner caducous in T. Falconeri.
