HOYA (Thomas Hoy was once gardener to the 

 Duke of Northumberland). Asclepiadiicew. More 

 than 50 tropical Asian and Australian climbing or 

 trailing evergreen shrubs, bearing thick, opposite 

 lvs.,and odd, often showy tls. in umbel-like clusters. 

 Corolla rotate, 5-lobed, thick and n 

 in appearance : crown of 5 thick and depressed 

 fleshy appendages : pollen-masses 10, short, fixed by 

 their base in pairs to the 5 glands of the stigma: 

 follicles acuminate, smooth: stems twining, or climbin 

 by means of roots. 



Hoyas are summer-blooming plants, of comparatively 

 easy culture. They need an intermediate or warm tem- 

 perature. Let them rest or remai; 

 (50° in a dryish place), but start them into growth 

 wards spring. In the summer they 

 plunged in the border, but better results are to be ex- 

 pected, as a rule, by keeping them in pots in the con- 

 servatory. In their growing and blooming season, give 

 plenty of sun and air. They propagate by cuttings of 

 the top growth in spring, and also by layering. The lat- 

 ter method is particularly adaptable to H. carnosa and 

 other species which climb by means of roots. A. P. 

 Meredith advises as follows: "For compost, use fibrous 

 loam, lumpy (or coarse) in two parts, to one of leaf- 

 mold, using charcoal pounded fine, brick dust, or lime 

 rubble if procurable, instead of sand. They are often 

 found doing well in loam and sand. When in growth 

 use weak liquid manure." 



A. Plant distinctly cUmiing. 



camdsa, R. Br. (B. Mofdskei, Tei.jsm. ). Wax Plant. 

 Twiner, and attaching itself to support by means of 

 roots ; ordinarily grown as a pot- or tub-plant, and reach- 

 ing 5-8 ft. high, but growing twice and more this height 

 when it has the opportunity: glabrous: Ivs. succulent 

 and shining, ovate-oblong, acute, short-stalked, entire: 

 fls. white with pink center, fragrant, in axillary or inter- 

 petiolar umbels, the crown-segments very convex, and 

 spreading into a horizontal star. Trop. Asia and Aus- 

 tral. B.M. 788, as Asclepias carnosa. A.G. 18: 34. -The 

 common species, and often seen in window-gardens. 

 After the bloom is over (in summer) keep the plant in 

 a cool place in order that it may remain half -dormant. 

 In late winter or spring, start it into growth. Do not cut 

 off the spur which remains after the fls. pass, for this 

 spur bears fls. again. The Wax Plant is .-.isv tm iri,in:ii.-e, 

 and it improves with age. Often tr;iiiic 'I ms a ]i, rnia- 

 nent cover for a glasshouse wall. In the South, it is 

 nearly everblooniing. There is a form (var. can.yiita) 

 with handsome variegated Ivs. L. 44. 



globuldsa, Hook. f. Hairy: Ivs. elliptic-oblong or long- 

 oblong, acuminate, rounded at the base, the midrib very 

 stout, the petiole an inch or less long: fls. pale straw or 

 cream color, the star-like crown-segments white, with 

 pink at the base, borne in dense, globular umbels: folli- 

 cles a foot or more long. Sikkim. F.M. 1880:406. G.C.

B.M. 4397. F.S. 4:393-4. -A noble Hoya, requiring very 

 rich soil and a rather high temperature. Although 

 naturally a very tall climber, it can be made to flower 

 in pots when 3 or 4 ft. high. 



aa. Plant trailing or nearly erect. 

 b611a, Hook. (ff. Pdxtoni, Hort.). Slender, bushy, 

 1-2 ft. high, pubescent: Ivs. an inch long, ovate-acute, 

 very short-stalked, somewhat recurved: fls. % in. across, 

 pure white, with very short and half-acute lobes, the 

 crown-segments boat-shaped and violet: umbels few-

HOLSEA (Dr. G. W. Hulse, of La., who collected in 

 Calif.). Compdsitw. This includes one of many woolly 

 herbs offered by Californian collectors. It grows a few 

 inches high and bears fls. with 20-30 yellow rays. Six 

 species of herbs, perennial, biennial or annual, all Cali- 

 fornian, glandular pubescent or woolly: Its. pinnately 

 lobed or toothed: fls. large, solitary, yellow or purple; 

 involucral bracts free, narrow; style branches obtuse: 

 pappus of 4 hyaline, lacerated, chaffy scales. Monogr.

n&na, Gray. Stems depressed, leafy at summit: Ivs. 

 pinnatifid or incised, petiole long-margined: peduncle 

 1-2 in. long: involucral scales in 2 series: rays 20-30.
