PROCHNYANTHES (liiv.k, ln,,,ln„i and flower;

 likened toaknci-). Amm-iillkh'ii-i-ii-. A genus closely 

 related to Polianthes and Bravoa, differing chiefly in the 

 shape of the flowers. Stems slender, from oblong 

 tubers which crown short, thick rootstock: Ivs. mostly 

 basal; inflorescence a lax spike or raceme: fls. always 

 in pairs, tubular below, abruptly bent at the middle, 

 bell-shaped above; stamens 6, included: fr. 3-celled, 

 many-seeded. Native of western Mexico. A genus, dis- 

 covered by Dr. E. Palmer in 1886, of which two species 

 have been described. It has been misspelled Prochy- 

 nanthes.

 the Southwest. The species of Prosopis may be spiny

PBOTfiA (from Proteus, the sea-god, who changed 

 into many forms; alluding to the bafiliug diversity of 

 the species). ProteAceir. Proteas are tender shrubs 

 which are among the most attractive and characteristic 

 plants of the Cape of Good Hope,— a region whose plant 

 life is unique. Their flower-heads are said to look like 

 a "glorified artichoke." Indeed P. cynaroides (Fig. 

 1962) is named from this very resemblance. {Cyna- 

 rtiides ini-ans , yn.ir.i-liU.- ; and Cynara is the artichoke. ) 

 It lias bii-bl pink 11. iwcr-heads which last several 

 ni.inibs. 'I'll.! siru.lur.i of tlie flower-heads is the dis- 

 liiii'(i\.- loainif ol Ilio wliole family of the Proteaceie. 

 The .showy ].arls ol; the flower-head are the bracts, 

 which are often rigid, colored, and overlap one another 

 like the scales of a hard cone or an artichoke. "When 

 the heads of P. cynaroides first open." says Watson, 

 "they are full of honey and ar« known to the Boers as 

 honey-pots." Tins hon.y is i-.,!l.M-t<-.l a:Hl nuide into a

as effective as big specimen rhododemlrons. "Fifty 

 years ago," writes Watson in 1891, "there were about .30 

 species of Protea included among popular greenhouse 

 plants in England; now one may safely say there is not 

 one, the few really under cultivation being only in 

 botanical collections." In 1881 Hooker wrote: "That 

 these and many other plants requiring like treatment 

 will be reintroduced, and will be the wonders of the
