240 SIR JOHN LUBBOCK ON STIPULES, 
The wings terminate at the upper ends in stipuliform processes, 
which are subulate, falcate, incurved, and about equal in length 
to the petioles. Besides these processes there are also numerous 
filamentous intrapetiolar processes, which stand erect, closely 
surrounding the axis. These may be protective. There are 
also some intrapetiolar glands. 
Lagerstremia indica has also wings to the stems which termi- 
nate in stipuliform appendages. On the pedestal a little to the 
inner side of the stipules are a pair of conical glands; they are 
pale green when young, excrete small globules of matter, and 
then turn black soon after the leaves are full-grown. 
Lythrum (L. Salicaria) bas similar stipular processes at the 
summit of the wings; they are quite minute. 
ONAGRARIEZ. 
Fuchsia (F. excortica) has short, subulate or conical, fleshy 
stipules, which serve to protect the buds. The petioles are 
subterete. 
PASSIFLOREX. 
Passiflora racemosa.—The leaves are palmately 5-nerved and 
3-lobed, slightly peltate at the base, conduplicate in bud, petio- 
late, stipulate; the petioles are terete, slightly flattening on the 
upper side, and with two glands below the middle, about 14 in. 
long. The stipules are large, foliaceous, obliquely ovate, obso- 
letely dentate on the side away from the petiole, erect and 
clasping the stem. In the bud stage the stipules are developed 
far in advance of their own leaves, so that each pair enclose 
their own leaf, the simple tendril in its axil, and the younger 
portion of the bud. Proceeding from the outside inwards, the 
stipules change considerably, being first ovate, gradually becom- 
ing smaller, then lanceolate, and finally subulate. In the other 
species of Passiflora examined, the stipules more or less com- 
pletely protect the bud, and the petioles are terete, provided 
with glands. 
UMBELLIFERÆ. 
The Umbellifere very commonly have sheathing-petioles, 
effectually protecting the bud. Among English genera this is 
the case with Astrantia, Apium, Helosciadium, Sison, Petro- 
selinum, Trinia, Egopodium, Carum, Sium, Pimpinella, (Enanthe, 
Æthusa, Feniculum, Keseli, Ligusticum, Silaus, Meum, Angelica, 
Peucedanum, Pastinaca, &c. The marginal membranes of the
