ANA 



their walls, unconsolidated, become sub- 

 ject to decay, which is soon exhibited in 

 a variety of untoward symptoms. Fruit, 

 in consequence, which has been produced 

 in a wet season is notoriously subject 

 to decay, except compensated by a 

 high state of the hygrometer, a circum- 

 stance which may perhaps account for 

 the small quantity of decay which has 

 been experienced in autumnal fruits. 

 In some cases, as in Elms, there is direct 

 extravasation, and then the fluid accumu- 

 lates, and at length forces its way through 

 the bark, producing permanent ulcers. 



Anastomosis. The union of veins or the 

 angle formed by their union, or of their 

 branches. 



Anastomosing. The uniting of veins, vessels, 

 or nerves. 



Anatropal. When an ovule is turned down 

 upon itself, so that the foramen, or true 

 apex, points to the base, and the chalaza 

 (which see) is at the apex. 



Anbury. A gouty, nodular condition of cer- 

 tain roots, such as Turnips,Cabbages, etc. , 

 commonly known as " Club Boot," (which 

 see,) arising from the presence of grubs. 

 It must not be confounded with dactyl- 

 orhiza, which is a very different affection, 

 and entirely independent of the attack of 

 insects. 



Anceps. Two-edged. 



Ancipital. Flattened or compressed; with 

 two edges more or less sharp; as the 

 stems of Sisyrinchium anceps. 



Ancipitous. Two-edged, as the stem of an 

 Iris, 



Ander. In names formed from the Greek, 

 ander is equivalent to the male sex or sta- 

 men; thus mon-ander signifies having one 

 stamen. 



Andreceacece. A natural order, or, accord- 

 ing to some, a distinct tribe of Mosses. 



ANE 



They do not, however, differ essentially, 

 being distinguished mainly by the longi- 

 tudinal splitting of the valves at maturity. 

 It consists of but two genera, Andrecea 

 and Acroschisma, an Antarctic genus, dis- 

 tinguished by the cylindrical capsule 

 splitting into four or eight valves at the 

 apex only. All of the species are of a pe- 

 culiar dark blue, and the leaves, which 

 are of a close texture, are of a beautiful 

 yellow or golden brown under the micro- 

 scope. 



Andrcecium. The male system of a flower. 

 The stamens taken collectively. 



Androgynous. A term applied to such 

 kinds of inflorescence as consist of both 

 male and female flowers; producing male 

 and female flowers on the same plant, or 

 on the same spike or head. 



Androphore. The tube formed by mona- 

 delphous filaments, as in the Mallow. 



Androus. In the composition of words de- 

 rived from the Greek, androus refers to 

 the stamens; thus, mon-androus signifies 

 having one stamen, etc. 



Anemosis. The condition known in timber 

 by the name of wind shaken. A trunk 

 which is apparently sound externally, 

 proves, when felled, to have given way 

 in the direction of the concentric layers 

 of which it is composed, so that the con- 

 nection between them is more or less 

 completely broken. This occurs in many 

 kinds of exogenous timbers, and is no 

 less common in foreign woods than in 

 those of native growth; being, as it is 

 supposed, due to the pressure of extreme- 

 ly violent gales. This, however, is very 

 doubtful, the effect being more probably 

 due to frost or lightning. Wind, how- 

 ever, may be injurious to trees without 

 producing absolute fractures, or separa- 

 tion of parts, by causing too rapid evapo-
