Mexico. Sonora, Guadaloupe Cafion, International Boundary Com- 
mission, 2035; Durango, Palmer 537; Oajaca, Villa alta, Liebmann 547; 
Lower California, Sierra de San Francisquito, Brandegee 6, Sept. 
1899; Jalisco, between Huejuquilla and Mesquitec, Rose 3570. In 
addition to these specimens in the National Herbarium, FourNIER gives 
the following: Inter Victoria et Rio Blanco (Karwinsky); Borrego prope 
Orizaba (Botteri 1213 in herb. VAN HeEuRcK); Mirador (Schaffner); 
Tacubaya (Schaffner 41 in herb. FRANQUEVILLE); Secus Amnem in her- 
bosis- pr. Pedregal (Bourgeau 444); Aguas Calientes (Hartweg 252). 
Liebmann 547 is also cited by FourRNIER and it is upon this specimen 
that I have based my identification of the species. FoURNIER’s description 
does not apply in all respects to the plants which I have included under 
this species. He states that the culms are pilose, which is not true of any 
of the specimens I have seen. Neither are both staminate spikelets pedi- 
celled, as he describes. 
The name first appears in Plant. Haitw: Addenda, p. 347. In the 
body of the work (p. 28) no. 252 is listed without description as T. dacty- 
loides ‘‘in saxosis, Aguas Calientes.” In the addenda this is corrected 
as follows: ‘“‘n. 252 est species a Tripsaco dactyloide distincta, T. lan- 
ceolata, Ruppr. ex cl. Rupprecht in Litt.”” Fournter (/.c.) cites T. 
lanceolatum Rupr. in Benth. Pl. Hartw. 247. Under the circumstances 
I think Hartwec’s no. 252 from Aguas Calientes should be considered 
as the type of 7. lanceolatum rather than coca gomgse s specimen, the 
first cited by FouRNIER. 
FourNIER cites as a synonym of this “7. acutiflorum Rupr. mss. in 
herb. Petrop.”” Under the rules of the recent code 7. acutiflorum was 
not published. FouRNIER (/. c. 69) also mentions without description, 
var. 8B monostachyum from San Luis Potosi (Virta 1447). I have not 
seen this specimen.
