NEMOPHILA 



best results have been attained by growing them in 

 pots in a cool greenlimisi-. Neniuphil:is are said to 

 do beautifully outdoors in JIaine. wlun- tlu' summer is 

 cooler and moister. In Scotland, N'cniophilas are es- 

 teemed most delightful garden plants. An odd thing 

 ahout Nemophilas is that cats are extremely fond of 

 rolling in them as they do in catnip.

N^NGA (Malayan name). PalmAcea;. Two or three 

 s]"-cics of IMalayan palms, one of which is cult, as 

 Arirti pnitiila. In Areca, however, the ovule is erect 

 and fastened at the base, while Neuga belongs to a large 

 group in which the ovule is fastened on the side and 

 more or less pendulous. Nenga is distinguished from 

 the 5 cultivated genera of this group (which are listed 

 under Hedyscepe) by the following characteristics : 

 staminate fls. with narrow sepals much surpassing the 

 petals; stamens 6; anthers erect. Nengas are graceful 

 spineless palms with erect, slender, ringed trunks: lvs. 

 terminal, equally pinnatisect; segments linear, acumi- 

 nate or obliquely 2-fld or 3-fid; margins folded back at 

 the base; primary nerves sparsely scaly below; rachis 

 3-sided; petiole short; sheath cylindrical, strongly ob- 

 lique at the throat: spadix with a short peduncle and 

 slender pendent branches: spathes 2, the lower sym- 

 metrical, lanceolate, folded, 2-crested, the upper un- 

 symmetrical, persistent, or lacking : bracts 3-fld. ; 

 bractlets scaly: fls. white: fr. ellipsoidal, smooth, red- 

 dish oiange. 



Wendlandid.na, Scheff (Areca pumila.Blume) . Stem

 nearly to the base; pinnae alternate, ensiform, acumi- 

 nate, 2}4 ft. long, }4-iyi in. wide, bright green, cori- 

 aceous, 2-ribbed; petiole slender; sheath sub-ventri- 

 cose, 2 ft. long. Java. Jared G. Smith.

NEPENTHES (name explained below). Ifepenthclcem. 

 About 35 species of insectivorous pitcher plants 

 which rank among the wonders of the vegetable king- 

 dom. The word Nepenthes occurs in the Odyssey, 

 where Helen threw a drug into the wine which was sup- 

 posed to free men from grief, anger and all ills. In de- 

 scribing one of these pitcher plants, Linnaeus said: "If 

 this is not Helen's Nepenthes, it certainly will be for 

 ail botanists. What botanist would not be filled with 

 admiration if, after a long journey, he should find this 

 wonderful plant ? In his astonishment past ills would 

 be forgotten when beholding this admirable work of 

 the Creator." 



There are about 35 species of Nepenthes, all tropical 

 and mostly Malayan. They are all remarkably alike, 

 and different from anything else in the W')rl(l. They 

 are probably supported in part by animal matter which 

 is caught in their pitchers. The fluid in tlie bottom of 

 the pitchers is largely secreted liy tlir jihiTits and is com- 

 parable to the gastric juice. It lirl|.s i.. decompose and 

 digest the food. The glands wliicli sicrcte this digestive 

 fluid may be seen with the aid of a hand-lens. This 

 fluid is used by the natives of Borneo as a remedy for 

 indigestion, as fresh ripe figs are often used. It has 

 been analyzed and found to contain pepsin. It is se- 

 creted before the lids open, even in the baby pitchers, 

 and the lid is believed to keep the rain from diluting 

 the viscid fluid. 



It is supposed that insects are attracted by nectar 

 glands situated near the mouth of the pitchers, and per- 

 haps also by the odor of the fluid. Later, the odor of 

 decomposing flies is thought to attract flesh-eating in- 

 sects, and thus a second harvest is secured. One spe- 

 cies is said to be still further specialized in its tastes. 

 Burbidge relates that N. Veitchii, from its peculiar 

 habit of growing on dead trees, catches mainly such 

 beetles and boring insects as exist in decayed timber, 

 and ants innumerable. There is. however, a species of 

 ant which outwits one of the pitcher plants; viz.. N. 

 bicalcarafa. " This ant's object is water, and to obtain 

 this it bores a hole through one of the large sugar-se- 

 creting glands of the stalk behind the pitcher, just
