PHYLLOCACTUS 



PHYMATODES 



1319 



lanceolate, often very long and large, undulate branches : 

 fls., including the tube, nearly 1 ft. long, 5-6 in. in ex- 

 pansion, opening, according to Schumann, in the day- 

 time. Honduras; also said to be found in Cuba. 



crenatus, Lem. In cult, commonly not much more 

 than 3 ft. high, freely branching from the lower part of 

 the stem: branches thick, with a strong 

 midrib, but thinning to the edges, which 

 are rather deeply crenate: fls. greenish 

 yellow outside, 6-10 in. long, and about 

 as much in expansion, day-blooming. 

 Honduras. 



anguliger, Lem. About 3 ft. high, 

 many-stemmed: basal stems cylindrical, 

 hard and woody, the large leafy branches 

 deeply cut in the margins, like the teeth 

 of a very coarse saw: fls. 5-8 in. long, 

 the tube very slender. South Mexico. 

 B.M. 5100. 



BB. Style red. 



stenop6talus, Salm-Dyck. (P. Idtifrons, 

 Zucc. ?). Branches very long and large, 

 crenate or somewhat serrate, acute or 

 acuminate: midrib and usually side ribs 

 evident; areolse with rather large scales 

 and dark bristles: fl. 8-10 in. long, 

 spreading and in full bloom bent back- 

 wards; petals narrow. Perhaps from 

 Mexico. Much advertised as the Queen 

 Cactus. 



Hookeri, Salm-Dyck. Branches long 

 but narrow,crenate-serrate, in age dark or 

 bluish green, often reddish on the mar- 

 gins; midrib strong and side ribs evi- 

 dent: fls. 6-8 in. long, yellowish white 

 within, reflexed in full bloom. Brazil 

 and Guiana. 



strfctus, Lem. Erect, branching, 

 reaching a height of 10 ft., with long 

 cylindrical branches and shorter, leaf- 

 like secondary branches: creiiatures or 

 teeth rather deep, unequal 011 the oppo- 

 site sides; bristles wanting: tube of the 

 fl. very long and slender, outer sepals 

 brownish, inner pure white ; the flower 

 opens late in the evening and closes be- 

 fore dawn; in full bloom the sepals are 

 very strongly recurved. Said to come 

 from the island of Cuba. Often found 

 in collections under the name of P. 

 latifrons. 



AA. Tube of fl. very short: fls. red. 

 Day bloomers. 



Ackermanni, Salm-Dyck. Fig. 1773. 

 Stems numerous, sometimes reaching 

 3 ft., somewhat recurved : branches usu- 

 ally less than a foot long, with evident 

 middle and side ribs ; areolse on the lower and younger 

 shoots bearing short bristles : fls. scarlet-red outside, 

 carmine-red within, the throat greenish yellow, tube 

 very short, the limb wide-spreading, 4-6 in. in diam. 

 B.R. 16: 1331. -Not known in the wild state. 



phyllanthoides, Link. Branches at length hanging, 

 cylindrical at base, lanceolate above: serratures obtuse; 

 middle and side ribs evident; bristles few: fl.-tube 2 in. 

 long or less, with spreading scales, the limb somewhat 

 longer, often striate. South Mexico. 



bif6rmis, Lab. Soon pendulous, the branches cylin- 

 drical: short branches leaf -like, the lower egg-shaped, 

 the upper more lengthened: fls. small, purple-red, less 

 than 2 in. in expansion: ovary without scales or angles. 

 Honduras. B.M. 6156. V. 2:159. 



In addition to the species described above, the following are 

 recognized by Schumann: P. acuminatus, caulorrhizus, Qcert- 

 neri, phyllanthus, Russelianus and Thomasianus. Of these, 



. Goertneri and Russelianns are usually included in Epiphyl- 

 lum; P. caulorrhizus is perhaps an unusual state of some other 

 species ; P. Thomasiamis described from a garden plant is 

 almost certainly a hybrid. Epiphyllum Guedneyri is by some 

 referred to Phyllocactus. KATHARINE BRANDEGEE. 



PHYLL6STACHYS is treated under Bamboo. P. 

 heterocycla, now in the trade, is in the supplementary list 

 on page 130. Since the Bamboo article was printed, 

 P. Marliacea has been introd. to American trade. It 

 is a rare bamboo, hardy in England, of which Mitford 

 says : "It presents such a marked resemblance to Phyl- 

 lostachys Quilioi that I do not think any 

 expert could tell them apart without ex- 

 amining the wrinkled base of the stem, to 

 which Phyllostachys Marliacea owes its 



1773. Phyllocactus Ackermanni (X 



Japanese name, Shibo-chikee, 'the wrinkled bamboo,' 

 and -which makes it so useful for canes and umbrella 

 sticks."

PHYMATODES (Greek, a close network). Polypo- 

 dicLcece. A genus of ferns allied to Polypodium and 

 sometimes united with that genus, but differing in the 

 fine copious irregular areolse formed by the anastomos- 

 ing veinlets and the free included veinlets spreading in 

 every direction. For culture, see Fern. 



A. Lvs. simple. 



Swartzii, Underw. (Polypbdium Swdrtzii, Baker). 

 Lvs. 2-4 in. long, %-l in. wide, narrowed gradually 

 toward both ends : sori in a single row each side of the 

 midrib. Florida Keys and tropical America. 



musaefdlium, Blume. Lvs. 1-3 ft. long, 3-4 in. wide, 

 with an acute point, the lower part winged to the base ; 

 main veins very distinct, with numerous small sori 

 almost covering: the whole surface. East Indies. Known 

 also as Drynaria and Polypodium musct folium.
