92 FIELD COLUMBIAN MUSEUM BOTANY, VOL. 2. 



LIPPIA NODIFLORA (L.) Michx. Fl. Bor. Am. 2:15. 



Verbena n. Linn. Ditches near Hamilton, Bermuda (i 18), a some- 

 what depauperate growth as compared with the more southern forms, 

 leaves 1.2-1.4 x -4 x -6cm., peduncles 2.5 cm., heads 4 mm. diame- 

 ter. Two forms of this species occur at Catano, Porto Rico, one low 

 and strongly prostrate with the peduncle the only strict part of the 

 plant, and very small leaves 1.2 x .5 cm., peduncles 3.5 cm., heads 

 .5 cm. (331); the other (176, 253) with the branches erect, leaves 

 3.5-5 x .7-1.3 cm., peduncles 5.5 cm., and heads .7-. 8 cm. in diame- 

 ter. Center of island of Grand Cayman in a boggy soil (1365); bor- 

 der of a brackish lagoon on the north shore of Cozumel (1595), leaves 

 2-2.5 x -8-1 cm., peduncles 5 cm. long, heads i cm. long, 6 mm. 

 diameter. Sandy ditches near Progreso, Yucatan (1722), a form with 

 broader leaves (2.5 x 1.6 cm.) and longer purplish heads (1.6 cm. long, 

 7 cm. broad). 



VALERIANOIDES JAMAICENSE (Linn.) Medic. Phil. Bot. 1:177. 



Verbena Jam. Linn. Stachytarpheta Jam. and Indica Vahl. Com- 

 mon on the smaller islands in Hamilton Bay, Bermuda (17); dry fields 

 and roadside banks at Catano (151); south shores of Culebras Island 

 (581), and at Guanica (687), Porto Rico; under coco trees at The 

 Creek, Cayman Brae (1173), where it is known as " Verveen " and 

 used as a purgative; and fields in the center of the island of Cozumel 

 (1568). These specimens all agree with the descriptions of Stachy- 

 tarpheta Indica a.ndjamaicensis, while the following take on the char- 

 acters given for 6*. strigosa Vahl. (= Valerianoides Jamaicense Indicum 

 forma strigosum (Vahl.) O. Kuntze.), having the linear-acuminate 

 setaceous bracts, which is the only character that in reality has any 

 claim to permanence. The dentation of the calyx-lobes, sulcation of 

 the rachis, and breadth of the bracts is very variable and too incon- 

 stant to form even a varietal distinction; this, together with the fact 

 that almost any dry field in the neighborhood of say Charlotte Ama- 

 lia, St. Thomas, or the Island of Grand Cayman will yield all the 

 species known as Indica, Jamaicense and strigosa, would indicate that 

 these are all merely forms of one species. Paget's, Bermuda (39), 

 hillsides above Charlotte Amalia, St. Thomas (419), fields in the 

 environs of San Domingo city (864), stony bed of a dry stream near 

 Port Antonio, Jamaica (900), and fields along the Bodden Bay road, 

 Grand Cayman (1340). 



PRIVA LAPPULACEA (L.) Pers. , Syn. ii., 1807. 



Common as a roadside weed at Catano, Porto Rico (337), Port 

 Antonio, Jamaica (921); San Juan Hill, Santiago de Cuba (1043, 

 1048), tall and widely branching, branches attenuate. Spot Bay, 

 Grand Cayman, (1286); low, compact and regular in form at center of 

 Island of Cozumel (1548), where it is called Xpakunpak, " Stick- 

 tight," alluding to the fruits. The Mayas use the bruised herb as a 

 remedy for gonorrhoea. 



CITHAREXYLUM QUADRANGULARE Jacq. Enum. PI. Carib. 26. 



A tall tree along roadsides and about plantations near Hamilton, 

 Bermuda (122), where it has all the appearances of an introduced
