 immediately from the root, and divided into several simple 

 diffused branchlets, clothed all round with leaves at most a 

 finger's height; leaves linear, blunt, almost menibranaceous, 

 having a longitudinal nerve, concave above, prominent be- 

 neath, perennial, the lower ones finally withering, but not 

 falling ; peduncle from the top of the branch straight, slender, 

 one-flowered ; corolla shining, snowy white. Native of the 

 mountains of Lapland, among stones covered with moss ; also 

 found on the coast of Labrador, and in Norway. 



2. Diapensia Barbulata. Leaves somewhat wedge-shaped, 

 downy beneath ; antherae spurred at the base. Found on tin- 

 mountains of North Carolina. 



Duma ; a genus of the class Polyaridria, order Monn- 

 gynia. GENERIC CHARACTER. Calir : perianth four or 

 five parted ; leaflets equal. Corolla: petals four or five, 

 obovate, trifid ; segments obtuse, the middle one longest ; 

 nectary of four or five small emarginate corpuscles surround- 

 ing the germen. Stamina; filamenta (twelve to twenty)

1. Dicera Dentata. Style one ; leaves oblong, acuminate, 

 toothed ; racemes simple, axillary, loose. This is an elegant 

 tree, bearing at the extremities of the branches abundance of 

 leaves, which are alternate, oval, or oval-oblong, blunt ish, 

 smooth, veined, bluntly serrate, petioled with a double 

 gland at their base : racemes axillary, simple, loose, solitary, 

 the length of the leaves ; flowers on very minute pedicels, 

 nodding; stamina sixteen when there are four, and twenty 

 when there are five petals. Fruit an oval berry, with a hard 

 stone in it; while unripe, ; .t is preserved after the manner of 

 olives. Linneus remarked twenty stamina in the Ceylonese 

 plant, and only eight in that from Java. Native of New 

 Zealand. 



2. Dicera Serrata. Styles four ; leaves opposite, cordate- 

 ovate, unequally serrate ; racemes lateral, compound. This 

 agrees with the preceding species in the structure of the 

 flowers, but differs in the fruit. Native of New Zealand.

 nia. GENERIC CHARACTER. Calix: five-leaved; leaflets 

 obovate, netted nerved, hairy without, smooth within, per- 

 manent. Corolla: monopetalous, inferior, rotate, suhcam- 

 panulate, five-cleft, the length of the calix. Stamina : fila- 

 menta five, subulate, spreading, placed alternately between 

 thedivisionsof the corolla, and only half the length ; an there 

 roundish. Pistil .- germina two, hairy ; styles two, divari- 

 cate, setaceous, the length of the stamina, arising on the in- 

 side from the base of the germina; stigmas capitate. Pen-

 five-leaved. CorolUi: rotate, inferior. Capsule: dicoccoua. 

 The only known species is, 



1. Dichondra Repens. Stem prostrate, creeping, branched, 

 round, leafy; leaves alternate, petioled, erect, kidney-shaped, 

 sometimes emarginate, above almost naked, below silky, ra- 

 diate-veined ; flowers small, rather nodding, on axillary fili- 

 form, simple, silky peduncles, scarcely the length of the pe- 

 tioles, and usually solitary. The specimens from different 

 countries differ in having the leaves naked above, or silky on 

 both sides ; also in the length of the petioles and peduncles ; 

 but these seem only to be varieties. Mutis sent it to Linneut 

 from New Granada; Commcrson found it at Buenos AyreB, 

 and in the island of Mauritius ; and it is likewise known to 

 be a native of Peru, Jamaica, and New Zealand.

 Filices. GENERIC CHARACTER. Fructifications, kidney- 

 shaped, lying under the edge of the frond at the lower sur- 

 face ; outer valve formed of the substance of the leaves itself, 

 inner membranaceous. The species are,
