ERIOCHILUS 



ERIOCHILUS (woolly lip). Orchidacene. A half- 

 dozen species of terrestrial orchids from Austral., with 

 email subterranean tubers and a solitary If. at the base 

 of the st. or higher up: fls. pink or white, 1 or more and 

 sessile on a scape or peduncle; labellum much shorter 

 than lateral sepals, the margins often with small and 

 erect lateral lobes. Some of the species have been 

 mentioned as greenhouse subjects, but they are horti- 

 culturally little known. 



ERIOCNEMA: Bertolonia. 

 ERIODENDRON: Ceiba. 



ERIODICTYON (woolly net, referring to the under 

 surface of the Ivs.). Hydrophyllacese. Four species and 

 many varieties (see Brand in Engler's Pflanzenreich, 

 hft. 59, 1913) of shrubs of Calif, and the Great Basin, 

 with alternate coriaceous entire Ivs., and white, purple 

 or blue fls. in scirpioid cymes. Apparently not cult. 

 E. Parryi, Greene = Nama. 



ERIOGONUM (Greek, woolly joints). Polygonacese. 

 About 140 species, W. N. American (with extension 

 intoMex.), herbs tufted sub-shrubs or slender annuals, 

 mostly densely woolly: Ivs. crowded at the base of the 

 st., alternate or whorled, entire: fls. small, perfect, in 

 an involucrate head, fascicle or umbel, mostly recurved 

 or reflexed with age, mostly white, rose or yellow; 

 perianth 6-parted; stamens 9; styles 3: fr. an achene, 

 mostly 3-angled. Now and then some of the species are 

 listed by dealers in native plants, but they can hardly 

 be regarded as cult, subjects. E. compdsitum, Douglas, 

 perhaps the best known, has very many minute neutral- 

 colored fls., dull white to rosy, borne in compound 

 umbels 5-6 in. deep and broad. B.R. 1774. The fol- 

 lowing have been advertised, but are practically 

 unknown in our gardens: E. campaniddtum, E. com- 

 pdsitum, E. fldvum, E. heradeoldes, E. incanum, E. 

 microthecum var. effiisum, E. niveum, E. niidum, E. 

 ovalifolium, E. racemosum, E. sph&rocephalum, E. 

 thymoldes, E. umbellatum. E. giganteum makes a mound 

 or mat many feet across. G.C. III. 28:337. Descrip- 

 tions of eriogonums may be readily found in the floras 

 of the western part of the U. S. 



ERIOGfNIA: Luetkea. 

 ERI6LOBUS: Pyrus. 



ERIOPHORUM (wool-bearing, from the Greek; 

 alluding to the heads of fr.). Cyperaceae. Perennial 

 rush-like plants, growing in swales: fls. in dense heads, 

 the perianth-bristles very numerous and often becom- 

 ing greatly elongated in fr. and giving the head a wool- 

 like appearance. None of them is known in cult., but 

 the following names have been offered by collectors for 

 bog gardens: E. alpinus, Linn.; E. cyperinum, Linn.; 

 E. linedtum, Benth. & Hook.; E. polystdchion, Linn.; 

 E. vaginatum, Linn. ; E, virginicum, Linn. All these are 

 wild in the northern states, and descriptions may be 

 found in the regular manuals. Eriophorum comprises 

 upward of a dozen species in the northern hemisphere. 



ERIOPHYLLUM (Greek, woolly-leaved). Compdsitae. 

 Herbs, mostly woody, and commonly with yellow- 

 rayed heads; one kind cult, in a few hardy borders is a 

 low, tufted, herbaceous perennial, with much-divided 

 Ivs., covered with wool beneath (each st. bearing about 

 5), and 8-rayed yellow heads 2 in. across, borne in a 

 loosely forking fashion on peduncles 3-7 in. long. The 



fenus was included in Bahia by Bentham & Hooker, 

 ut is now kept distinct largely because of the per- 

 manently erect involucral bracts: seeds mostly 4- 

 angled, and pappus of nerveless and mostly pointless, 

 colorless portions. Actinolepis is included in this genus 

 by some authors. There are about a do/en species, in 

 N. W. Amer. E. caespitdsum, Douglas (Actinella 

 landta, Pursh, not Nutt. Bahia landta, DC.), described

above, has been advertised. Either moist or dry 

 ground, Mont, to Brit. Col. and S. Calif.; very variable. 



ERIOPSIS (Greek, like Eria, an orchid of the Epi- 

 dendrum tribe, which it resembles when not in flower). 

 Orchidacese. Five or six South American orchids of the 

 Vanda tribe allied to Acacallis and Warrea, requiring 

 coolhouse treatment as given to Cattleya; epiphytes. 



Leaves 2 or 3, long, plicate: racemes 2 or 3, basal; 

 fls. open, small, but showy, maxillaria-like; lip 3-lobed, 

 the lateral lobes broad and erect and inclosing the 

 column, the middle lobe small and spreading and some- 

 times 2-lobed. About half a dozen species in S. Amer. 



biloba, Lindl. Pseudobulbs 3 in. long: Ivs. lanceo- 

 late: fls. 1 in. across; sepals and petals yellow, with 

 orange-red margins; labellum yellow spotted with 

 brown. Colombia. B.R. 33:18. 



rutidobulbon, Hook. Stouter in habit than the above: 

 pseudobulbs wrinkled, dark-colored: racemes drooping; 

 sepals and petals orange-yellow, with deeper colored 

 margins; labellum white, with purple spots. Antioquia, 

 in exposed positions on the sts. of palms. Peru. B.M. 

 4437. 



Helenas, Kranzl. Said to be the finest in the genus. 

 It differs greatly in habit from the other members; the 

 pseudobulbs (standing 16 in. high) somewhat resemble 

 those of Epidendrum Brassavolse, but are much stronger, 

 and bear 3 long, coriaceous dark glossy green linear- 

 lanceolate Ivs. The fls. are twice as large as those of 

 E. biloba, and are borne on tall, arching scapes. The 

 sepals and petals are orange-colored, margined with 

 purple, the lip similar, but with a yellow blotch, 

 spotted with purple at the base. Peru. 



E. Fuerstenbergii, Kranzl. Racemes up to 12 in. long; fls. about 

 1 Yi in. across; sepals and petals brown outside, orange with brown 

 border inside; lip whitish, densely dotted with purple. 



OAKES AMES. 



ERIOSTEMON (Greek, wooUy stamens). Rulacex. 

 Coolhouse evergreen shrubs from Australia, with starry, 

 fiye-petaled flowers an inch wide, of white or blush- 

 pink. Very little known in America, but abroad con- 

 sidered amongst the finest of hard-wooded winter or 

 spring-blooming Australian plants. 



Leaves alternate, entire, glandular-dotted: infl. 

 axillary or terminal, solitary or in clusters; calyx and 

 corolla 5-parted, rarely 4-parted; stamens 8-10, free, 

 shorter than the petals; anthers pointed: fr. 2-valved. 

 1-seeded. Much care is needed to produce well-trained 

 specimens. 



Eriostemons are among the most beautiful of Aus- 

 tralian hard -wooded plants. They are propagated 

 from cuttings made of the points of half-ripened wood. 

 Choose pieces about 3 inches long, and insert in a pot 

 filled with one part finely sifted peat, and two parts 

 sharp sand. Water them and set in a case in a tempera- 

 ture of 55 to 60, shading them from the sun. After they 

 have rooted, pinch out the heart of the shoots, and when 

 they show signs of breaking, transfer them singly 

 into small pots in equal parts of peat and sand. When 

 well rooted in these pots, give them a shift about two 

 sizes larger, using good fibrous peat, in rather a lumpy 

 state, and about a fifth part of good sharp sand, adding 

 a little of finely broken charcoal. This compost may 

 be used for all future pottings. If large plants are 

 wanted quickly, it is better to grow them indoors all 

 the year round, but they will not set flowers so well. 

 Eriostemons flower in the smallest sized pot in spring, 

 if they are grown outdoors all summer. The outdoor 

 treatment ripens the wood thoroughly and the result 

 will be seen when flowering time arrives. These plants 

 are liable to run into strong shoots to the detriment of 

 the weaker ones. When this is observed, cut them well 

 back, and this will preserve the symmetry of the plant. 

 During their growing period they should be syringed 

 freely. This helps to soften the wood and secure
