membranous spicultc and much smaller leaves. It appears to be very abundant on the 

 Isthmus of Panama, and especially near the Lion Hill station of the Pacific Railroad. 



3. C. ABIETIFOLIA, Griscb. in Flora Brit. West-Indian Islands, 529. " Racemo fere 



simplici, spiculis 5-10 pedicellatis, glumis valde inajqualibus," foliis angustissimis 

 spinoso-acumiuatis, vaginis ore nuclis. — Arundo, no. 5, P. Browne, Civil and Nat. 

 Hist. Jamaica, 139 (teste Grisebach). 



Hob. in Jamaica, Wilson ! ; lud. occid., Swartz. Vidi folia tantum in herb. Hooker, s. v. Grisebach. 



" Culmus alte scandens/' internodiis glabris 3-5 poll, longis, 2 liueas diametro, ramulis foliiferis (inter- 

 nodiis 1-3-6 lin. longis) fasciculatis. Folia disticha, |-2 poll, longa, 1^-2 lin. lata, linearia, rigida, 

 subsessilia, glaucescentia, margiue cartilagineo serrulato-scabra, apice spinoso-acuminata, nervo 

 central! subtus prominente, secundariis a tertiariis non discerneudis. Vagina margine ciliatse, 

 demum glabrescentes, dense imbricatae, ore biauricuJatEe, eligulata;. Racemus brevis, folia sequans, 

 fere simplex, patulus, spiculis 5-10 pedicellatis, pedicellis 1 lin. longis, rhaelii angulata scabra. 

 Spicula lanceolato-acuminata, 3 lin. longa, glumis valde insequalibus, inferiore subobsoleta. Floseuli 

 neutri inaequales, inferior glumam superiorem sequans; superior amplectens, 5-nervis, acuminatns, 

 flosculum hermaphroditum lineari-acuminatum puberulum 3-nervem sequans. Palea superior bica- 

 rinata, acuminata, inferiore paulo brevior. 



Having seen only leaf-bearing specimens of this, I have taken the description of the 

 inflorescence and its details from Grisebach. He, however, mentions only " three sterile 

 glumes; " but as the plant, if it is really a Chusquea, must have had four, I have pre- 

 sumed that the lowest one was very small and nearly obsolete, and have so described it. 

 The foliage bears a remarkable general resemblance to that of some species of Coniferse. 



4. C. Venezuela, Steud. I. c. 337. " Panicula suhracemoso-divaricata, simplici, spiculis 



sessilibus, foliis lanceolatis." 



Hab. in Venezuela, Funck et Schlim, no. 494. s. v. Steudel. 



Culmus , " ramis ad nodos 3-4-nis, supremis binis vel solitariis. Folia sparsa, laneeolata, acuta, 



1—4 poll, longa, 2—4 lin. lata, brevipetiolata, glaucescenti-viridia, concoloria, tenuistriata, scabri- 

 uscula. Vagina apice fimbriatse, margine nudse. Panicula subracemoso-divaricata, simplex, rhachi 

 glabra; spiculis 3-floris, 2—5 lin. longis, ad angulos rhacheos sessilibus. Glumce membranacete, ner- 

 vosse, acutiusculse, flosculis multo breviores. Palea inferior 5-7-nervis, acuta; superior (floseuli 

 fertilis) margine ciliata." — Steudel. 



I know nothing of this plant except from Steudel' s description, given above verbatim. 

 It is the only species in the whole genus with sessile spiculte ; and on this account I think 

 it probable that it may belong to the genus Arthrostylidiiim. 



5. C. PiNiFOLiA, Nees in Linnaea, ix. 490. Panicula semel composita, depauperata, con- 



tracta, vix i^ollicari, glumis minimis ohtusis, palea inferiore mucronato-acuta, foliis 

 lineari-subulatis pungentibus. — Trin. in Act. Petrop. I. c. 614, icon. 340 ! ; Rupr. I. c.
