216 THE LOEANTHACEAE OP AUSTKALIA, ii., 



Supplementary notes. — P. celastroides always forms round, compact shrubs, 

 1-3 feet in diameter. Branches short divaricate. Union often obscured by 

 matted adventitious roots, causing irregular swellings on the host; sometimes 

 the main attachment is enlarged to a diameter of 2-4 inches on very old plants; 

 the adventitious roots are shorter than those of P. eucalyptoides and are more 

 firmly attached to the host, very rarely free as in that species. Leaves mostly 

 oblong elliptical, 1-nerved with numerous fine jDarallel veins at an angle of 

 about 45 degrees, with reticulate veins between them. Cymes minutely pubasoent 

 on the pedicels and bracts, bearing 6-18 flowers, nearly all pendulous, but often 

 crossing each other owing to the curved calyx. Buds 3-4 cm. long, sea-green 

 underneath, shading on the upper surface from a deep rose pink, plate 120, to 

 carmine-red. No. 1, plate 114 (Rep. de Col., Dauthenay). Petals about the 

 same colour inside. Free portion of the filaments dark violet. No. 2-4 plate 

 193 (Rep. de Col.), the adnate portion carmine-red, the upper filaments the 

 longest, with a small solitary gland on the geniculate portion close to the anthers. 

 Anthers yellow, elliptical, 1 mm. long, opening before the flower expands, smaller 

 than those of P. eucailyptifolius. Stj'le curved in bud, exceeding the stamens 

 when the flower opens. Stigma small, often minutely bi-lobed. Fruit usually 

 pear-shaped, 7-11 mm. long, 4-6 mm. in diameter, very smooth and glossy, turn- 

 ing a strawberi-y red, especially on the upper surface, ripening somewhat later 

 than P. eucalyptifoUus, without the yellow top of that species, and usually free 

 from any depression at the top, but marked by two slightly-raised rings sur- 

 rounding the angular disc, which is also more or less conspicuous. Endocarp 

 thick and leathery; viscin sac 5-8 mm. long, the spongy base very small and 

 globose; seed turbinate, somewhat angular at the top, 3-4 mm. long; endosperm 

 white, embryo clavate, 2 mm. long; embryonic cotyledons spathulate, remaining 

 in the endosperm when germination takes place; hypocotyl very short, about 1 

 mm. long, disc broad. Primary leaves broadly ovate to spathulate 5 mm. long. 



Synonyms. — Lorcmtlms celastroides Sieber, Lorantlius maytenifolius A. Gray 

 (in Wilkes, Expl. Exped., p. 739, plate 99, in part), Dendrop'htho.e celastroides 

 Mart, {vide Etting'shausen in Uber die Blatt. der Loranth., p. 20, Taf. ix.. Figs. 

 7-9). 



Q. Don (Gen. Hist., iii., 432) places Loranthvis celastroides Sieber, No. 244, 

 with Nuytsia floribimda R. Br., probably on account of the versatile anthers. 



Port Jaclsson. in the vicinity of Sydney, is probably the type locality of 

 this species. It is evident that Sieber obtained his specimens close to Sydney 

 in 1825, where it is still very common, especially along the coast. It rarely ex- 

 tends more than ten miles beyond the salt water limit of the tidal creeks and 

 rivers. 



This species has a decided dislike for Eucalyptus and Acacia. After a 

 thorough search over a large area, and investigations of the specimens in the 

 National Herbarium, I have only found one example of this species living upon 

 a Eucalyptus. It is frequently found parasitic upon P. eucalyptifoUus and vice 

 versa, and in all cases observed, both species maintained their own individuality; 

 I cannot find one example where these two species, P. celastroides and P. 

 eucalyptifoUus, pass into each other or show any signs of mimicry, even when 

 living on each other. 



Examples of double parasitism of these species may possibly have given 

 rise to the idea that they were one and the same plant, as it is frequently met 

 with in the field. For instance P. celastroides and P. eucalyptifoUus gave ex- 

 amples of double parasitism on the Eastern Plane, Platanus orientalis, and
