no other Culture, but to keep them 

 clear from Weeds. The fecond Sum- 

 mer thefe Plants will flower, and 

 produce Seeds ; but if the Roots are 

 not dilturbed, they will continue fe- 

 veral Years, and produce Seeds an- 

 nually : therefore, where the Plants 

 are defignM to remain, the Seeds 

 mould be fown in Drills, at about 

 fixteen Inches apart ; which will al- 

 low room to dig the Ground between 

 the Rows every Winter ; whereby 

 the Roots will be greatly encourag'd, 

 and the Weeds will be better deftroy-

TRANSPLANTING OF 

 TREES. Vide Planting. 

 TRIBULUS, Caltrops. 



The Characters are ; 

 // bath a Flower compofed of feveral 

 Leaves, which are placd circularly, 

 and expand in form of a Rife ; out of 

 nvhofc Empalcment rifes the Pointal, 

 which afterward becomes a turbina- 

 ted Fruit, composed of federal Parts y 

 which have Thorns, collected into an 

 Head ; and having fcveral Cells, in 

 which are inclos'd oblong Seeds. 

 The Species are ; 



1. Tribulus terrefiris, ciceris fo- 

 lio, fruclu aculeato. C. B. P. Land- 

 caltrop, with a Chich-leaf, and a 

 prickly P'ruit. 



2. Tribulus terrefiris major 

 Curajj Tavi:us. Prod. Par. Bat. Great- 

 er Land American Caltrops. 



3. Tribulus terrefiris America- 

 ?ius, fruclu turb'.nato, foliis lanugi- 

 nofis. Plum. Cat. American Land- 

 caltrops, with a turbinated Fruit, 

 and downy Leaves. 



4. Tribulus terrefiris Indise Ori- 

 entalis, fcliis vicitf fubrotundis & 

 cvillofts. Infi. R H. Eafi ■ India 

 Land-caltrops, with roundifli and 

 hairy Vetch leaves. 



The firft Sort is a very common 

 Weed in the South of France, in 

 Spain and Italy, where it grows 



among Corn, and on molt of the 

 arable Land, and is very trouble- 

 fome to the Feet of Cattle ; for the 

 Fruit, being armed with itrong 

 Prickles, run into the Feet of the 

 Cattle, which walk over the Land. 

 This is certainly the Plant which is 

 merttion'd in Virgil's Georgics, under 

 the Name of Tribulus ; no' mod of 

 his Commentators have applied it to 

 other Plants. 



It is call'd in Englifh, Caltrops, 

 from the Form of the Fruit, which 

 refembies thofe Inftruments of War 

 that were call in the Enemies Way 

 to annoy their Horfes. 



This Plant is preferv'd in feveral 

 curious Gardens in England, for the 

 fake of Variety. It is propagated 

 by Seeds, which ihould be fown in 

 Autumn ; for thofe which are kept 

 out of the Ground till Spring, com- 

 monly remain in the Ground a whole 

 Year, before the Plants come up. 

 Thefe Seeds mould be fown on an 

 open Bed of freih light Earth, where 

 they are defign'd to remain ; for, as 

 it is an annual Plant, it doth not 

 bear tranfphnting very well, uniefs 

 it be done when the Plants are very 

 young. In the Spring, when the 

 Plants come up, they ihould be care- 

 fully clear'd from Weeds ; and where 

 they come up too clofe, fome of the 

 Plants Ihould be pulled o.;t, to give 

 room for the remaining Plants to 

 grow. After this they will require 

 no other Culture, but to keep them 

 clear from Weeds. In June they 

 will begin to flower, and their Seeds 

 will ripen in Augufl and September ; 

 which if permitted to fcatter, the 

 Plants will come up the following 

 Spring, and maintain their Place, if 

 they are not overborne with larger 

 Weeds. 



The Branches of this Plant trail on 

 the Ground ; and when the Plants 

 are vigorous, will ipr^ad tc a great
