short (3 cm.) spikes. The same form from Progreso, Yucatan (1735),

 the leaves, from the latter station (1655). 



Heliotropium Indicum Linn. Sp. PI. 130. 



Old fields near Caguas (211) and on south shores Culebras Island 

 (647), Porto Rico. Suburban banks and fields Charlotte Amalia, St. ,/

 irregularly repand crenate, 9x5 cm., spines 7 cm.; the same form

 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 

 spikes 3 cm. long. 



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 

 Cuba, the former with lanceolate leaves 4.5-7 x 1.3-2 cm., acute and 

 tending to apiculation, the latter with broadly lanceolate leaves

 ulate and scattered-hairy 2-4.5 x 1.1-1., 9 cm., spikes slender, about 

 gem; 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 -
