[March, 



L. lo"'™ ; D. o""° , oi6, forthe full ones ; 

 R. 620 Hops. 



d. Groups presenting two types; one 

 containing sections of ten, very large, 

 full or with thick walls ; polygonal 

 in form, with obtuse or re-entrant 

 angles and rounded contours. The 

 other quite voluminous, composed of 

 very small sections of a clearer blue, 

 their forms rounded, but sometimes 

 irregular and distorted These two 

 kinds of sections are enclosed in a 

 yellow network slightly adherent, 

 whose meshes are often empty. The 

 isolated sections separated from the 

 meshes appear like sections of cotton, 

 but they present to view many well- 

 marked concentric layers which some- 

 times distinguish them ; the central 

 opening often contains a yellow gran- 

 ulated substance or one which remains 

 without color. 



Longitudinally, bundles easily di- 

 vided with needles into a confused 

 mass of large and very fine fibres, 

 well separated from each other ; these 

 are full, smooth or striated, with 

 plainly marked folds of flexion, or 

 else they are in ribbons ; the central 

 canal rarely apparent, or indicated 

 by detached masses of yellow granu- 

 lations which show themselves toward 

 the points ; the latter fibres have 

 rounded ends usually large. 

 L. 15'""'; D. o""", 025, p. the largest; 

 R. 430 .... Paper Mulberry. 



c. Small groups of not very large 

 blue sections, separated by a yellow, 

 generally thick, network ; f o r m s 

 rounded, some with salient angles, 

 very full, with central opening very 

 small, pointed or linear, often filled 

 with yellow grains. Concentric lay- 

 ers few, but plainly marked ; the outer 

 layer paler than the interior and some- 

 times tending to a yellow color. The 

 other sections irregular, like those of 

 the hemp but much smaller, having 

 a less pronounced tint than the full 

 ones ; central cavity linear or open, 

 sometimes garnished with yellow 

 grains. Groups of woody fibres are 

 frequently present, recognized by their 

 yellow color. 



Fibres blue, violet or yellow, short, 

 curly, full, round, regular, and of very 

 small diameter ; the central canal is 

 indicated by a very fine line ; the yel- 

 low envelope often overlaps the points 

 which are not usually slender, but 

 rounded at the end, bifurcated and 

 sometimes furnished with lobes.

R. 400 The Broom. 



SECTION II. 

 Monocotyledons. 

 This section includes the Alfa (embracing 

 under this name the Lygeiim Spartum 

 as well as the Stipa tenacissimd) and 

 the Pine Apple (Ananassa sativa.') 



1. Irregular groups composed of 

 blue intermingled with yellow sec- 

 tions ; the concentric layers often 

 plainly marked, the outer one some- 

 times colored yellowy the inner ones 

 being blue ; forms rounded or oval, 

 rarely presenting straight surfaces or 

 sides ; in the center a point, often of 

 a yellow color, indicates the inner 

 canal. These sections are accom- 

 panied by groups showing the yellow 

 fibro-vascular bimdles. 



Fibres short, blue, fine, very full, 

 smooth, curly and of a uniform and 

 regular diameter ; having a veiy fine 

 yellow line in the middle represent- 

 ing the central canal ; the points are 

 rarely slender, but rounded, truncated, 

 and bifurcated or notched. 



L. 1""°', 5 : D. o"™, 012 ; 



r. 125 Alfa. 



2. Groups very compact, quite vo- 

 luminous, and often in the form of a 

 cross ; very small sections of the fibres 

 of a blue or very pale violet tint only 

 appearing when they are very thin. 

 These sections are enclosed in a quite 

 thick yellow network ; their forms are 

 usually rounded, but sometimes po- 

 lygonal ; the cavity appearing in the 

 form of a point or a very short line. 

 The thick sections are greenish or 

 even yellovs^. Among these groups 

 are found sections of fibro-vascular 

 bundles, in which the tissue which 

 fills the center is of a blue color and 

 surrounded by a border formed by one
