long lax raceme, greenish-purple, varying much in intensity, some- 
times nearly green, sometimes all dark purple. We can perceive no 
essential difference in these varieties, between which there arc inter- 
mediate forms : the shape and size of the lip, although variable, as 
well as its structure, distinguish this species from the next, which are 
the only two European ones of this section we are able to recognise. 
2. E. palustris Sw. (Marsh II.) ; leaves lanceolate, bracteas 
mostly shorter than the slightly drooping flowers, upper lobe 
of the lip roundish-oval or obovate broadest at or above the 
middle undulato-crenate very obtuse or refuse with two crests 
at the base longer than the sepals. Serapias Scop. : E. B. t. 
270. S. longifolia L. 
Moist and marshy places, especially in a chalky soil. If.. 7. — 
Stem 1 foot high, purplish above. Outer sepals purple-green, inner 
ones and lip white, with rose-coloured streaks at the base. 
** Upper lobe of the lip naked, recurved. Column elongate. Anther 
on a short thick stalk. Ovary sessile, twisted. Cephalanthera Rick. 
3. E. grandi/lora Sm. ( large white II.) ; leaves ovato-lanceo- 
late sessile, bracteas longer than the glabrous ovary, sepals 
erect obtuse, upper lobe of the lip very blunt or rounded 
shorter than the rest of the perianth. Serapias L.: E. B. t. 
271. Cephalanthera Bah. E. pallens Sw. 
Woods and thickets, chiefly in a chalky soil. If. 5,6. — Stem 
a foot or more high. Flowers remote, racemose, quite erect; sepals 
all nearly equal, large, oblong-ovate, obtuse, cream-coloured, concave, 
including the small lip which is also white but yellowish within. 
Dr. Lindley ascribes to this and the following species a truly terminal 
anther, and therefore places them in the group Arethusece. 
4. E. ensifulia Sw. (narrow-leaved, white H.) ; leaves lanceo- 
late much acuminate subdistichous, bracteas subulate much 
shorter than the glabi’ous ovary, sepals erect, outer ones sub- 
acuminate inner acute, upper lobe of the lip roundish somewhat 
obtuse or slightly pointed shorter than the rest of the perianth. 
Serapias L. : E. B. t. 494. Cephalanthera Rich. 
Mountainous woods, but not general. . 5, 6. — Flowers approxi- 
mate, subspicate, more or less diverging, pure white. 
5. E. ruhra Sw. (purple II.) ; leaves lanceolate, bracteas 
longer than the downy germen, perianth spreading, upper lobe 
of the lip acuminate as long as the inner sepals marked with 
raised wavy lines. Serapias L. : E. B. t. 437. Cephalanthera 
Rich. 
Very rare in mountainous woods, in England. “ Bank sloping to the 
south on Hampton Common, Gloucestershire:” Sm. 2f. 6,7. — 
Sepals purplish-red. Lip almost white.
