Tabor.—The Leaf Buds of Archytaea alternifolia. 1021 
EXPLANATION OF PLATE LXXIX. 
Illustrating Mr. Tabor’s paper on Archytaea alternifolia. 
Fig. 1. Entire leaf bud ; leaf teeth are seen on the second leaf at t. Nat. size. 
Fig. 2. Lower epidermis in surface view. Stomata with 3-5 subsidiary cells, g = guard cells, 
= subsidiary cells, x 200. 
Fig. 3. Transverse section of mature leaf. m.k. = mucilaginous hypoderm cells with swollen 
stratified walls, m.e . — mucilaginous epidermal cells, m.m. = mucilage cell, g = guard cell, 
s — subsidiary cell. X 175. 
Fig. 4. Portion of young leaf showing three teeth and related vascular strands. Cleared with 
eau de Javelle. x 28. 
Fig. 5. One tooth from the same preparation as that from which the preceding figure was 
drawn, i, — intercellular space, p — thick-walled cells forming a plinth for the tooth, x 240. 
Fig. 6. Horizontal section of margin of leaf, with tooth in nearly median section. The terminal 
tracheides of two vascular bundles are seen associated with narrow elongated cells of epithem tissue. 
t — tracheide, ep. — epithem, i =- intercellular space, x 265. 
Fig. 7. Similar section in which the tooth was cut almost transversely near its base. In this 
and in the preceding section the tracheides and surrounding cells were torn by the razor, p — thick- 
walled cells at base of tooth, other lettering as in Fig. 6. x 300. 
Fig. 8. Tangential section of the epidermis of a tooth with intercellular spaces, e = epidermal 
cell, i — intercellular space. X 600. 
Fig. 9. Transverse section of bud immediately above the insertion of the outermost leaf. 
st = stem, l.t. = leaf traces, Lb. = leaf base, b = axillary bud, c = colleters. x 10. 
Fig. 10. Longitudinal section of base of bud showing portions of five leaves, t — row of 
immature teeth on fourth leaf, other lettering as in Fig. 9. x 10. 
Fig. 11. Transverse section of colleter. (Cell contents omitted in most cells.) m.c. = mucilage 
cavity, x 265.
