sible over the year, and sufficient ice kept on the farm. The company- 

 owns and cleans all the cans, which hold 100 lb, of milk. From cans 

 for delivery to consumers the supply is drawn from the bottom. The 

 sweet milk is kept in round cans, and the skim in square cms. To 

 equalise the distribution of cream with the milk, the tube or pipe, in 

 which the discharge valve is placed is continued to the top of the can, 

 and contains rows of small holes through which the milk is drawn from 

 the whole depth of the milk. 



FERNS : SYNOPTICAL LIST— XXXVI. 



Synoptical List, with descriptions, of the Ferns and Fern- Allies of Ja- 

 maica. By GK S. Jenma.n, Superintendent Botanical Gardens, 

 Demerara. 



22. Nephrodium pubescens, Desv. — Rootstock slender, about as thick 

 as a quill, repent, slightly scaly ; stipites contiguous or scattered, erect, 

 rather slender, channelled, naked or lightly pubescent, 9-15 in. 1. ; 

 fronds deltoid, acuminate, about a foot each way, bi-tripinnate, 

 chartaceous ; throughout pubescent ; light green rather glossy above ; 

 pinnae spreading, lowest pair deeper on the inferior side, all acuminate, 

 and petiolate J- \ in., central ones lanceolate 4-6 in. 1. in. w., the 

 basal pinnule oa the upper side the largest ; pinnulse ovate or lanceo- 

 late-acuminate, the smaller cuneate at the base, f-lj in. L Jrd J in. w. 

 the point entire, lobed or pinnatifid within ; the segments on the upper 

 side at the base largest and more or less free, entire or toothed, ^rd \ 

 in. 1. 1^—3 li. w. ; teeth sharply acute or mucronate ; veins pinnate in 

 the ultimate divisions, the branches not reaching the edge ; with the 

 sori dorsal or terminal upon them ; involucres pale, delicate, fugacious. 

 — Hook, and Grrev. Icon. Fil. t. Aspidium, Swartz. Polypodium, Linn. 

 102. Phegopteris, Fee. 



a. var. breviculum, Jenm. — Fronds small, elongate-deltoid 

 (occasionally lanteolate) 4-6 in. 1. 1J-3 in. w., bipinnate ; stipites and 

 rachises slender. 



Common in damp woods among the lower hills, reaching up to 1,500 

 ft altitude ; distinguished by its creeping rootstock, pale colour, pilose 

 surfaces, relatively large pinnuke, and sharp teeth, which would be 

 pungent if the texture were stift'er. The lowest anterior veinlet often 

 terminates about halfway to the margin. Var. a, of which A. Klotzschii. 

 Hook. Cent. Ferns, t. 23, is a good representation of its outline and 

 cutting, is distinct in size and form from the type, which characters 

 hardly vary, and are constant under cultivation. It grows in the 

 fissures of rocks, often fully exposed. Usually only the interior segment 

 on the upper side of the pinnules is free but in some states others are 

 as well. 



23. N. ochropteroides, Baker. — Rootstotk erect or oblique, paleaceous 

 on the crown ; stipites tufted, a foot or more 1. stone-brown, channelled, 

 rather glossy, scabrous, clothed below with light or ferruginous linear- 

 acuminate scales ; fronds subdeltoid 9-12 or more in. each way, qudri- 

 pinnate, coriaceous, light green, paler beneath, naked and glossy except 

 the rachises which are pubescent, especially down the channel, and 

 brown; pinnee spreading, the upper lanceolate, the lower deltoid-
