acute. Bases of the culms hard and corm-h'ke, as in C, strigosus, 

 L. ; rootstocks very slender, with delicate scales. 



Florida, from the herbarium of Dr. Ferdinand Rugel, now 

 incorporated with that of I. C. Martindale, an enthusiastic col- 

 lector and patron of botany, for whom the species is named. 

 Collected also by Chapman at Appal achi cola, and marked in his 

 herbarium at Columbia College, as C. oviilaris^ Torr, with which 

 it has but little affinity. In habit it resembles C 



Cyperus echinatus (Ell.) {Mariscus echinatus, Ell., Sk., 

 i, 75> 182 1 ; Cyperus Baldwinii, Torn, Ann. Lye, iil, 270, 1836.) 

 This species, not hitherto reported from beyond the limits o{ the 

 United States, though from its collection by the botanists of the 

 Mexican Boundary Survey, and by Buckley in the Valley of the 

 Rio Grande, we may suspect its occurrence in northern Mexico, 

 comes now from Jamaica (J. Hart, No. 1034.) 



»^Var. MULTIFLORA (Chapm.), n. van Spikelets ten to even 

 twenty five-flowered, the latter elongated to 20-25 mm. {C. 

 Baldwinii^ van multiflora, Chapm., in Torr. Herb.) 



Cyperus ferax, Richard. Not reported from Mexico nor 

 Central America, in Hemsley*s Botany of the Biologia Centralis 

 Americanae is 1980, 1979 Miiller from Orizava, 438 Bernouilli 

 from Mazatenango, Guatemala, and also from Chihuahua (E. 

 Wilkenson, in Herb., J. Donnell Smith.) 



Cyperus ochraceus, Vahl, is also omitted from the Botany of 

 the Biologia. It appears to be quite widely distributed, how- 

 ever, having been collected by Botteri, as already noted by me, 

 and is represented in Mtiller's collections from Orizava by Nos. 

 1981 and 1982, and was collected by Tiirckheim at Coban, 

 Guatemala, in 1887, and distributed by Capt. J. Donnell Smith 

 as No. 1262.

-Cyperus humilis, Kunth, var. ELATIOR, n. van Culms 

 erect, 12 to 15 cm. high; cauline leaves about equalh'ng the 

 culm; those of the involucre about 2> the longest 15 cm. in 

 length. Otherwise nearly as in the type, which we have in C. 

 bright, Plantae Cubanse, No. 700. 



»^oIlected by H. von Turckheim, on the river-bank, near 

 Coban, Guatemala (Distr. J. Donnell Smith, No. 705).
