12 Botanical Report. 
species above mentioned are of a very varied character, for 
they are representatives of no less than 83 out of the 94 
Natural Orders into which the 1680 species which are com- 
prised in the London Catalogue are divided. 
The families which are not known to occur wild in our 
district, excluding the limes (Tiliacez) are 11 in number :-— 
1. Frankeniacez, which contains but one species (F. levis), 
the Sea Heath. 
2. Tamariscacez, which also contains but one species (T. 
Anglica), the Tamarisc. 
3. Elatinacez, which has two species, the Waterpeppers. 
. Polemoniacez, which has but one species (P. ceruleum), 
the Jacob’s Ladder. 
Pinguiculacez, which has eight species, the Butterworts 
and Bladderworts. 
6. Plumbaginacee, which contains six species, the Sea 
Lavenders and Thrifts. 
7. Elzagnacez, which has but one species (H. rhamnoides),. 
the Sea Buckthorn. 
8. Asaracez, in which are two species, the Asarabacca. 
and the Common Birthwort. 
g. Empetracee, with a single species (E. nigrum), the: 
Crowberry. 
10. Eriocaulonacez, which also has but one species, (E.. 
septangulare), the Pipewort, and 
11. Marsileacez, also containing one species (P. globu- 
lifera), the Creeping Pillwort. 
The last-named species was formerly found on Esher 
Common, and may still grow there, but there is but little chance 
of any of the other excepted families being represented in our 
Flora, except, possibly, the Elatinaceez and Pinguiculacee.. 
The two species which are comprised in the first of these two 
families are both found in our county; and of the Pingui- 
culacez one species of Butterwort occurs in the south east of 
England, and two species of Bladderwort are included in the 
Flora of Surrey. 
On the other hand the Frankeniacee, Tamariscacez, and 
Elceagnacee are confined to the sea coast; and the same 
remark applies to the Plumbaginacez, except as to one species 
of Thrift which is found on the top of some of the Scotch 
mountains. The Jacob’s Ladder, again, is hardly a wild flower 
at all. Wherever it is found it has probably escaped from 
cultivation. Both the species of Asaracez are also considered 
by many to be introduced plants, the Birthwort being confined 
to the south and south-east of England, and being found only 
near old ruins. This is to be explained by the fact that this. 
plant was much cultivated in gardens in olden times, on
