PACHYRHIZUS 



PACKAGES 



can not be distinguished except by tasting the root. 

 To have good roots, the blossoms and seed-pods must 

 be kept pinched off, for if they are allowed to mature 

 the roots are not good. The roots mature in about 5 

 months and may be allowed to remain in the ground 

 longer, as they become sweeter ' as the cold season 

 approaches. 



2697. Pachysandra procumbens. (Flowers Xl. Leaves XH-) 



AA. Lfts. lobed. 



palmatilobus, Benth. & Hook. (Dblichos palmatiloba, 

 Moc. & Sesse). Fig. 2696. St. twining, glabrous or 

 pubescent : Ivs. pubescent, often long-petioled, pinnately 

 3-foliolate, terminal 1ft. broadly ovate, deeply 3-lobed, 

 with lateral lobes often somewhat 2-lobed, lateral Ifts. 

 less deeply 2-4-lobed, lobes ovate, mucronate: fls. 

 purplish, in long-peduncled racemes. Trop. Amer. 

 Not so common, root smaller and less cult, than the 

 preceding. p. L. RICKER. 



PACHYSANDRA (Greek, thick stamen). Buxaceas. 

 Perennial herbs or subshrubs of some value as ground- 

 cover in shade for their more or less evergreen leaves. 



Stems prostrate or ascending, 6-12 in. high, from 

 rootstocks, scaly below: Ivs. alternate, usually coarsely 

 toothed, evergreen or deciduous, 3-nerved: spikes 

 staminate above, with a few pistillate fls. at the base of 

 each; staminate fls. with 4 sepals and stamens and a 

 rudimentary pistil; sepals variable in the pistillate fls.; 

 petals none; pistil 3-celled, 2 ovules in each cell, the 

 3 styles spreading, filaments thick, exerted, conspicu- 

 ous, usually white : seeds smooth. Two species known: 

 of low and dense growth, with very early fls. attractive 

 to bees, and masses of bright green Ivs. Easily prop, 

 by division in ordinary soils. Good for rockeries. 



In the vicinity of Boston, P. procumbens is decidu- 

 ous, and is desirable only from the feature of its curi- 

 ous flowers borne so extremely early in the spring. The 

 foliage is of a dingy color and deciduous, whereas P. 

 terminalis is a true evergreen with thick, glossy foliage 

 forming a dense mat, making a very desirable low- 

 growing cover-plant, succeeding admirably either in 

 full sun or partial shade. The variety variegata is a 

 very choice cover plant for ornamental effects. (J. 

 Woodward Manning.) 



procumbens, Michx. MOUNTAIN SPURGE, Fig. 2697. 

 One foot high or less: Ivs. ovate to obovate, 2-4 in. 

 long: spikes of white or purplish fls. from the base of 

 the sts. March-May. W. Va. to Fla. B.M. 1964. 

 L.B.C. 10:910. B.R. 33. G.C. III. 55:335. 



terminalis, Sieb. & Zucc. Smaller: Ivs. obovate- 

 cuneate: the small spikes of whitish fls. terminal. May. 

 Japan. Var. variegata, Hort., with white variegated 

 Ivs., is in the trade.

PACHYSTIMA: Pachistima. 



PACHYSTOMA (Greek, meaning thick mouth, refer- 

 ring to the thick lip). Orchiddcese. Terrestrial orchids 

 with leafless scapes from underground nodose rhizomes : 

 pseudobulbs producing 1-2 Ivs.: sepals and petals 

 similar, the lateral sepals occasionally forming a chin, 

 all upright; labellum 3-lobed, forming a sack with the 

 base of the column; anthers bent over; pollinia 8, 

 lying in pairs and bound into 4 by elastic threads. 

 About 10 species, chiefly E. Indian and Malayan, but 

 1 from Trop. Afr. P. Thomsoniana, Reichb. f. (Ancis- 

 trochUus Thomsonidnus, Rolfe), is the most commonly 

 cult, species. It has large fls. with white sepals and 

 petals, and the lip has green erect side lobes thickly 

 dark purple-spotted and a narrow recurved midlobe 

 which is white nearly covered with deep purple lines. 

 Trop. Afr. B.M. 6471. J.H. III. 51:147. G.C. II. 

 12:582 (note), 624, 625; 18:501. Gt. 30:1061. A 

 warmhouse plant. P. Thomsoniana is now referred to 

 Ancistrochilus by Rolfe. Ancistrochilus has 2 species 

 and is readily distinguished from Pachystoma by the 

 pollinia being united to a single stipitate appendage 

 as well as by the remarkable lip and spreading segms. 



PACHYSTROMA (Greek for thick layer). Euphor- 

 bidcese. The one species, P. ilicifolia, Muell. Arg., is a 

 shrub or tree of S. Brazil rarely cult, and chiefly in 

 botanical gardens; the oily seed has been used in medi- 

 cine. Juice milky : Ivs. simple, pinnately veined, spinu- 

 lose dentate: fls. apetalous; sepals valvate or slightly 

 imbricate; stamens 3; styles 3, undivided; ovules 1 in 

 each cell of the ovary. Related to Manihot.

PACKAGES for horticultural produce. The choice 

 of a package and the method of packing horticultural 

 products are very important considerations to every 

 grower who is interested in establishing a reputation 

 for his goods. The commercial value of well-grown 

 produce of choice varieties may be greatly lessened or 

 utterly destroyed if the attempt is made to market 

 it in poor uninviting packages, or if it is poorly 

 packed. Inferior produce or poor varieties are some- 

 times sold for prices above their real value when 

 packed in an extra attractive way. 



2698. A good pack of apples in a box-tray.
