PSEUDOFANAX (from pseudos, false, and Panax). 



OP.D. AraliacecB. A genus comprising four species of 



greenhouse, evergreen, glabrous shrubs or small trees, 



two of which are from New Zealand, and the others 



natives of Chili. Flowers in small, racemose or paniculate 



umbels ; petals and stamens five, the former valvate ; 



pedicels articulated below the flowers. Fruit sub-globose. 



Leaves digitate or simple ; leaflets coriaceous, often 



slightly toothed. The two species here described are those 



introduced to cultivation. For culture, see Aralia. 



P. crassifolium (thick-leaved). I. alternate, 2ft. long, and about 



lin. broad, thick and fleshy, having a few obtuse, distant lobes 



along the edges, which end in a short spine; upper surface 



dark olive-green ; midrib prominent, deep orange. A. 10ft. New 



Zealand, 1846. SYNS. Aralia crassifolw, Panax crassifolium, 



P. longissimum. A garden variety, known as punctata, is 



in cultivation; the leaves are not so thick as those of the 



type, the marginal lobes are not so blunt, and the colour is 



dark olive-green, with a continuous line of emerald - green 



blotches all along, on either side of the midrib. 



P. Lessonii (Lesson's), fl. rather large ; umbels branched, on 



stout peduncles ; pedicels racemose. Jr. ovoid, Jin. long. I., on 



old plants, three to flve-foliolate ; leaflets lin. to 4in. long, sessile, 



oblong- or obovate-lanceolate, slightly acute, sinuate-serrate or 



quite entire, very thick and coriaceous ; petioles 4in. to Bin. 



long. New Zealand. A small, glabrous tree, with very stout 



branches. SYN. Aralia trifolia. 



PSEUDOS. A prefix, in Greek composition, signi- 

 fying false ; e.g., Pseudo-costate, false-ribbed. 



PSEUDOSCORDUM. A synonym of Notho- 

 scordnm (which see). 



PSEUDOTSUGA (from pseudos, false, and Tsuga). 

 OBD. Conifera*. A monotypio genus, the species being 

 a tall, hardy, evergreen tee. For culture, &c., see Finns. 

 A large number of forms, sports, or seedling variations, 

 are grown in some nurseries, under distinctive names. 

 P. Douglasli (Douglas').* I. flat, blunt, entire, pectinate, silvery 

 beneath, lin. to IJin. long, two-rowed, cones ovate-oblong, about 

 4in. long, IJin. to Ijin. broad ; scales broad, rounded, with con- 

 spicuous, projecting, deeply-toothed bracts, h. 100ft. to 180ft 



under name of P. Lindleyana.) SYN. Abies Douylasii. There 

 are several varieties, the best of which are : 

 P. D. pendula (drooping). A variety with elegant, drooping 



branches, h. 50ft. 



P. D. Standishii (Standish's). A seedling, with larger leaves 

 than the type, with a deeper green tint above, and quite silvery 

 beneath. 



P. D. taxilolla (Yew-leaved). A form with longer leaves and 

 stouter branches, of much dwarfer habit, 

 and more massive, than the normal 

 species. 



PSIDIUM (from Psidion, the 

 Greek name of the Pomegranate). 

 Guava. OBD. Myrtacece. A genus 

 of stove trees, shrubs, or rarely sub- 

 shrubs, often villous or tomentose, all 

 (perhaps with the exception of one 

 inhabiting tropical Eastern Asia) 

 natives of tropical and sub-tropical 

 America, one being broadly cultivated 

 over the tropical regions of the globe. 

 Upwards of 100 species have been 

 enumerated, bufr, according to the 

 authors of the " Genera Plantarum," 

 this number may be considerably re- 

 duced. Flowers rather large or rarely 

 small, on axillary or lateral, one to 

 three (rarely many) flowered pe- 

 duncles, cymose ; calyx tube cam- 

 pannlate, urceolate, or pear-shaped, 

 scarcely exceeding the ovary, or more 

 or less produced ; lobes of limb four 

 or five ; petals four or five, spreading. 

 Berries globose, ovoid, or pyriform. 

 crowned with the calyx limb, or 

 naked; seeds few or many, sub- 

 Leaves opposite, penniveined. The 



reniform, hard. 



species thrive best in a compost of sandy, fibry loam.
