Euphorbia Esula, Linn. 
Provinces [1]2--5----- 11--1415. Chiefly in 14. 
Alien. Oyb. ii. 860. iii. 505. Bot. Gaz. ii. 98. One of the 
recorded localities for this plant may afford us an illustration of the 
difficulty in distinguishing between artificial and natural stations. 
In the Supplement to the Flora Bathoniensis a station is recorded 
for it as a true native, with the name of Mr. T. B. Flower as the 
authority. Several years afterwards that gentleman “ ascertained 
this species was planted in the locality. The root had been taken 
from the Prior Park Botanic Garden by one of the students.” In 
English Botany this is distinguished into two varieties, genuina 
and Pseudo-Cyparissias ; the latter known by its narrower leaves. 
Euphorbia salicifolia, Host. 
Province- 15. Forfarshire; George Lawson, in Phytol. iii. 345. 
Alien. Cyb.ii. 3866. ‘Sub-species of E. Esula”; Eng. bot. vii. 117. 
Euphorbia Cyparissias, Linn.

Alien. Cyb. ii. 861. iii. 505. Cornwall to Fife. 
Euphorbia Lathyris, Linn. 
Provinces 12345---91011-18-15. 
Alien. Cyb. ii. 864. iii. 505. Introduced; DC. geog. bot. rais. 
Becomes a sort of weed, a self-sown biennial, in shrubberies; but 
is killed by severe winters. There is weighty authority for holding 
it a native in some counties, notably, Professor C. C. Babington 
for Somerset, Mr. Borrer for Sussex, Mess. Webb and Coleman 
for Herts. It readily renews itself ‘on sufferance” in shrub- 
beries and gardens; and it is thus likely to do so in coppices 
afterwards, if a single seed should once be introduced and grow to 
plant-hood there. 
Euphorbia Characias, Linn. 
Province - 5. Malvern, Worcester. Needwood, Stafford. 
Error. Cyb. ii. 8365. A misnomer, probably of amygdaloides. 
Buaus sempervirens, Linn. 
Provinces 12845--8-10. Always planted? 
Alien? Cyb. ii. 866. Surrey, locally established. Perhaps 
introduced; A. DC. in Geog. bot. rais. 686.
