*Tnefe Plants have no great Beauty 

 in their Flowers ; fo are feldom pre- 

 ferred in Gardens for Pleafure ; but 

 by fuch Perfons as are curious in Bo- 

 tany, they are preferved to add to 

 the Variety. 



DIAPENSIA. Vide SanicuJa. 



DICTAMNUS ALBUS. Vide 

 Jraxinella. 



DICTAMNUS, Dittany. 

 The Characters are ; 



*Fhe Flower - cup confifls of two 

 Leaves ; after that another athwart 

 the former ; and again a third in like 

 manner ; until a fcaly Head be thence 

 formed: out of the Centre of all thefe 

 Scales grows a Flower, who/e Creft 

 is erccl, roundifh, and bifd : the Beard 

 is divided into three Parts : thefe lit- 

 tle Flowtrs come forth from leafy 

 Scales after the manner of the V zr ti- 

 tle Plants, in a long loofe Spike. 

 The Species are ; 



1. Dictamnus Creticus. C. B. 

 Dittany of Crete. 



2. Dictamnus mentis Sipyli, ori- 

 gani foliis. Flor. Bat. Dittany from 

 Mount Sipylus, with Wild-marjoram- 

 leaves. 



The firft of thefe Plants hath been 

 renowned for many Ages, upon the 

 account of its fovereign Qualities in 

 Medicine. This is generally brought 

 over dry from the Levant, and is 

 ftill ufed in fome of the grand Pre- 

 parations. 



This Plant, although a Native of 

 a warmer Country than ours, yet is 

 tolerably hardy, and will endure the 

 Cold of our common Winters, if 

 planted in the open Air, provided it 

 is planted in a dry fandy Soil. It 

 may be propagated by planting Cut- 

 tings in any of the Summer-months ; 

 which mult be fhaded and watered 

 until they have taken Root ; after- 

 wards they may be either planted in 

 Pots, or in a warm Border under a 

 South Wall, where they will remain 



D I 



for feveral Years, unlefs deftroyed 

 by violent hard Frofts ; for which 

 Reafon 'tis advifeable always to keep 

 a Pot or two of this Plant under a 

 Frame as a Referve, in cafe thofe 

 abroad mould be deftroyed. This 

 Plant produces its Flowers infune 

 and July ; but the Seeds are feldom 

 perfected in this Climate : and al- 

 though there is no great Beauty in 

 the Flowers of this Plant ; yet, for 

 the Variety of its round hoary fvveet- 

 fmelling Leaves, it deferves a Place 

 in very good Gardens. 



The iecond Sort was found upon 

 Mount Sipylus, by Sir G. Wheeler in 

 his Travels, and by him fent to Ox- 

 ford. This is a very neat Plant, af- 

 fording long Spikes of Flowers, 

 which continue a long time in Beau- 

 ty ; and deferves a Place with the 

 former in every good Garden. This 

 is propagated and managed as the 

 other in every refpeft. 



DIER VILLA [This Plant was 

 fo named by Dr. Toumefort, from 

 Mr. Die'rville, a Surgeon, who 

 brought it from Acadia"]. We have 

 no Englifh Name for this Plant. 

 The Characters are ; 



// hath a Flower confifling of one 

 Leaf which is tubulous, and divided 

 into fve Parts : the Ovary, which 

 crowns the Point al, is produced from 

 the Centre of the two-leavd Calyx : 

 and after the Flower is paffed, it be* 

 comes a pyramidal Fruit divided into 

 four Cells, which are filed with fmall 

 Seeds. 



We have but one Species of this 

 Plant at prefent in Europe ; which is, 



DiER villa Acadienfis fruticofc{, 

 fore luteo. Acad. Reg. Scien. Shrub- 

 by Diervilla of Acadia, with a yel- 

 low Flower. 



This is a very low Shrub, feldom 

 rifing to the Height of three Feet in 

 England-, but is very fubjett to 

 fpread at the Root, and become 



bufhy.
