UESOSFINtDIUM (Greek compound; meaning ob- 

 scure). OrchidHcece. The plants cultivated as Mesospi- 

 nidium are referred by some to the genus Cochlioda. They 

 have the habit of a slender Odontoglossum, with sheath- 

 ing lvs. at the base of the pseudobulbs. Fls. in racemes 

 or panicles; sepals and petals sub-similar, expanded; 

 labellum with 2 longitudinal ridges, adnate to the col- 

 umn, with rounded lateral lobes and a narrow middle 

 lobe: column long or short: pollinia 2, seated on a rhom- 

 boid pedicel. These plants are evergreen coolhouse 

 orchids, and thrive well in baskets of peat and moss, 

 with plenty of water. Cochlioda has about 5 species, of 

 which the following is often cultivated: 



sanguineum, Reichb. f. Pseudobulbs oval, 2-lvd., 

 mottled: lvs. ligulate, sharp-pointed, shorter than the 

 many-fld. drooping panicle: fls. numerous, small, vivid 

 rose; the lower sepals are partially united, oblong; 

 petals cuneate-ovate. Peruvian Andes. B.M. 5627. 



M. vulcdnicxnn. Reichb. f., is described as Cochlioda vuIcan- 

 ica (p. 341), its proper name. HeINBICH HaSSELBRING. 



MfSFILUS (Greek, substantive name). BosAcetr. 

 Mespil. Medlar. From Pyrus, with which this genus 

 is united by British authors, Mespilus differs in bear- 

 ing the flowers singly on leafy growths of the season 

 (the fruits, like the quince, having no true detachable 

 peduncles as pears and apples do), and in having the 

 top of the ovaries not covered by the over-growing 

 receptacle. There is but one species of true Mespilus, 

 but some authors (e. g. , Focke, in Engler & Prantl's 

 "Die Natijrlichen Pflan- 

 zenfamilien ") include 

 some of the Cratjrgus 

 species in tlic t;eniis. 



The .■..nun. Ill M.^tlar 

 is Mespilus Germanica, 

 Linn., native to Central 

 Europe. To a consider- 

 able extent in parts of 

 Europe it is grown for 

 its acid fruits, but in this 

 country it is very little 

 known. It is perfectly 

 hardy in central New 

 York, and Its cultivation 

 requires no special treat- 

 ment or skill. It makes 

 a twiggy, tough-wooded 

 bush or small tree, 10 to 

 15 feet high, bearing 

 large white blossoms late 

 in May or early in June, 

 after the leaves are full 

 size. The foliage is soft 

 and luxuriant ; leaves 

 lance-oblong or long-ob- 

 long, pubescent, simple, 

 serrate. The fruit (Pig. 



1397) remains hard and austere until mellowed by 

 frosts. With the freezing and the incipient decay, the 

 fruit becomes brown and soft. It is usually picked 

 after it is touched by frost and laid away on shelves 

 or in drawers in a cool, dry room; the ripening process 

 which follows is known as bletting. When finally soft- 

 ened, it is agreeable for eating from the hand, parti.*- 

 ularly for those who enjoy fruit-acids. It also makes 

 good preserves.
