12. amplifolia. "L. smooth above, villoso- 

 pubesccnt beaeatli, broadly obovate and oblong, 

 cordate at base. Lobes broad, short, entire or 

 somewhat crenate. Fr. on short spikes. Cups 

 hirsute when young. l.T. 4, 5, Shady val- 

 leys. Sic." — Guss. 



13. ESsculus. Rachis very short. L. attenu- 

 ate, on long stalks, sinuate. Lobes angular or 

 dentate, downy on both sides when young. 

 I.T. 4. Pdm. K. Nap. ? 



S. Leaves permanent. 

 i. Teeth not spinescent. 



14. bivoniana. " L. somewhat cordate, 

 ovato-oblong, smooth above, hoary beneath, 

 sinuato-lobate or tripartite : the middle lobe 

 Uneari -oblong, entire or inciso-dentate. Cups 

 solitary, sessile. Scales spreading. T. 4, 5. 

 IFood of Gerace, Sic." — Guss. 



15. Ilex. L: generally repand and dentate, 

 each tooth with a sharp muero ; hut vary- 

 ing much ill form and margin ; sometimes 

 quite entire. Bark even, not corlcy. T. 5. 

 s. Em'ope. 



In general, the Rachis is very short, and 

 the lower Fl. nearly or quite sessile ; but I 

 have a specimen from s. Fr. with a long rachis 

 and sometimes as many as 6, quite separate 

 flowers, of which the lowest is far from the 

 stem. It was a dwarf plant, with slightly 

 dentate L., and may be a species. 



16. Suber. L. like those of Q. Ilex, iut 



when gathered in floioer the ufper side be- 

 comes black in drying, and both L.-stalk 

 and Fl.-stalk are longer. Bark chinky and 

 corky. T. 5. s. Fr. 1st. s. It. What the 

 Pseudo-suber of Santi, mentioned by Tenore, 

 may be, I do not know. 



ii. Teeth of L. spinescent. 



17. coccifera. L. cordate at base, spinoso- 

 dentate. S. s. Fr. It. lapygia. 



^. humilis. L. downy beneath. 



728. CORYLUS. 



1. Avellana. Stipules oblong, obtuse. Cal. 

 of Fr. campanulate, lacero-dentate. L. subro- 

 tundo-cordate, acuminate. S. 2, 3. Woods 

 and thickets. 



2. tubulosa. Stipules oblong, obtuse. Cal. 

 of Fr. tubular, conlracted at top. L. subro- 

 tundo-cordate, acuminate. S. 2, 3. Woods. 

 Istria, abundant. — Koch. 



729. CARPINUS. 



1. Betulus. Scales of Catkin tripartite. 

 Div. lanceolate. T. 4, 5. Woods. 



2. duinensis. Scales of Catkin ovate, un- 

 divided. T. 4, 5. Austrian shore. — Koch. 



3. Ostrya. Invol. of Fr. nflated, membra- 

 nous 1 Catkin ovate, drooping. L. ovate, acu- 

 minate, somewhat cordate. T. 4, 5. adr. G. It. 



Tribe II. SALICINEM 

 730. SALIX. 



I have laboured in vain to reduce the Wil- 

 lows into a regular system, and I have there- 

 fore thought it the safest way to bring together 

 aU that had been enumerated as species by 

 Hooker and Koch ; adding occasionally a few 

 observations of Babington or of my own, or 

 deduced from the plates of ' Eng. Bot.' I do 

 not believe that any person, however weU 

 skilled iu other parts of botany, would be able 

 to determine the species from the descriptions. 

 Some degree of traditional knowledge in this 

 genus is indispensable. It is probable that not 

 one-half, perhaps not one-fourth, of the forms 

 here enumerated are genuine species ; but I am 

 unable to determine which should be adopted 

 and which omitted. I am not, however, pre- 

 pared to admit that each tribe, the Is'igricantes 

 for instance, is in fact only one species ; and I 

 should stiU less consider this to be the case 

 with the Bicolores ; but even if it were so, I 

 am stiU unable to point out satisfactory marks 

 to distinguish these different tribes. All that 

 I could do, I have inserted in its place. 



In aU the Salices the typical form of the 

 Fruit seems to be that of a pear reversed, 

 often described as lanceolate or subulate on an 

 ovate base : in some, as in S. purpurea, not 

 much longer than broad ; in others 3 or 4 times 

 as long. The shape of the L. is taken fi-om 

 the middle of a healthy shoot, not springing 

 immediately fi-om the root, nor fi'om the trimk 

 of an old tree. 



Sect. I. Catkins lateral ; the stalk producing 



no leaf-buds, but falling off with the catkin. 



Stalk of fertile Catkins leaiy. Scales of 



one eolom*. 



A. Fragiles. Scales falling off before the 



fruit is ripe. Trees, and for the most part 



only bearing fruit as trees, while in all the 



other sections (except, perhaps, the Friti- 



Hosce) the plants produce fi'uit as Shrubs
