 locality is tall and shrubby with very long spikes 15-24 cm. Fields 

 about El Caney, Santiago de Cuba (1029), a very low form (8 cm.) 

 with large, pilose, cordate reticulate leaves 8 x 5.5 cm. and dwarfish

HELIOTROPIUM PARVIFLORUM Linn. Mant. 2:201. 



Waste ground south shores of Culebras Island (585) and Guan- 

 ica (691), Porto Rico. Common in waste places about Charlotte 

 Amalia, St. Thomas (436), leaves ovate blunt 1.7-3 x 1-2-2 cm., plen- 

 tifully scattered-hairy above, spikes 6.5 cm. Environs of San 

 Domingo (781), leaves as in the previous plant but acute and sparingly 

 scattered-hairy above, developed spikes 12 cm. Shores of the Bay of 

 Santiago de Cuba (102), leaves ovate lanceolate 4-5 x 1.7-2 cm. spar- 

 ingly scattered-hairy above, strongly reticulate veined above and 

 beneath. San Juan Hill (1049) and Morro Hill (1084), Santiago de

 ulate and scattered-hairy 2-4.5 x i.i-i., 9 cm., spikes slender, about 

 9 em. long when fully fruited. Woodlands and opens center of the 

 island, Cozumel (1538), leaves broadly lanceolate, spikes short (7 cm. 

 in full fruit), scattered hairiness reduced to a minimum. An infu- 

 sion of this plant is used in domestic practice on this island in such 

 cases of illness as are supposed to be due to a thick condition of the 

 blood. It is called by the Indians "Ne-maax," or in the feminine 

 gender, " X-ne-maax," " Monkey-tail," and by the Mexicans of 

 Yucatan " Rabo de Mico," meaning the same, in allusion to the per- 

 fect resemblance of the inflorescence to that appendage. A similar 

 form collected along the roadsides of Progreso, Yucatan (1704), but 

 with almost the hairiness of H. Indicum, and with large ovate-lanceo- 

 late reticulate leaves 4.5-6.5 x 2.3-3 cm -
