Physosiphon 



( 195 ) 



Physurus 



grn., or red (jsyn. Stelis 



punctulatus, grn. 

 spotted pur. 



yel., 



PHYSOSIPHON. 



(Stove epiphytal Orchids (ord. Orchidace:c), 

 resembling the Pleurothallises in habit, and 

 needing similar treatment. They are of little 

 horticultural value, but Loddigesii is occasionally 

 met with in collections. 



Principal Species : 



Loddigesii, Jy., yel., 

 tnbata). 



Other Species : 

 guatemalensis, yel., pur.; 



close to Loddigesii. 

 Limlleyi, grn. , sepals red ; 



close to Loddigesii. 



PHYSOSPERMUM. (BLADDER SEED.) 



Glabrous perennial herbs (urd. Umbelliferai) of 

 little horticultural value. The (lowers are white, 

 in umbels, and the leaves are much cut. 



PHYSOSTEGIA. (FALSE DRAGON 

 HEAD.) 



Two or three species of hardy, erect-habited 

 herbs (ore/. Labiataj), all from North America. 

 They need the same culture as the members of 

 the genus Dracocephalum. 



Principal Species and Varieties : 



virgiiiiana, H' to 4', Jy., 

 Sep., flesh pk. or pur.; 

 very variable 



Dracocephalum varie- 

 gatum and virgini- 

 aimm). 

 alba, flowers wh. 



Other Species : 



imbricata (xcc virginiana 



speciosa) . 

 intermedia, 1' to 3', sum., 



pk. or pur. 



nana, dwarf, pk. (//. 

 Regelii of gardens). ' 



speciosa, a fine var. 

 with large spikes (xyiw. 

 imbricata and Draco- 

 cephalum speciosum of 

 Sweet). 



parviflora, 1' to 2', sum., 



pk. 

 Regelii (see virginiana 



liana). 



PHYSOSTELMA. 



Two species of climbing stove shrubs (ord. 

 AsclepiadesG), answering to the same cultural 

 treatment as Hoya. Probably only one species is in 

 cultivation, and that one is by no means common. 



Principal Species : 



Wallichii, My., grn., yel., Ivs. leathery (*yia. 

 campanulatum and Hoya campanulata). 



PHYSOSTIGMA. (ORDEAL BEAN OP 

 OLD CALABAR.) 



There is only one species of Physostigma two 

 by Index Kem-nsis (ord. Leguminosas), a tall, 

 climbing, stove herb, of no garden value but with 

 a sinister reputation of its own. The seeds are 

 virulently poisonous, and are employed by the 

 natives of Old Calabar in their witch-finding 

 functions. Suspects are made to eat the Beans 

 until they vomit or die, the first contingency being 

 taken to prove innocence, the second guilt. The 

 poison has also the property of causing contraction 

 in the pupil of the eye. 



Only Species : 



venenosum, flowers pur., pods 6" long, seeds 1" 

 long, nearly round. Ordeal Bean. 



PHYSURUS. 



Stove, terrestrial Orchids (iird. Orchidaceas), 

 bearing prettily marked leaves for the most part. 



Physopoda (fee Thripg). 



The genus is closely related to Ancectochilus, and 



j several species have figured in both genera. The 



cultural hints given for Anesctochilus will apply here 



also. Comparatively few species are in cultivation. 



Principal Species : 

 argenteus, 4", Ivs. 2i" 



long, I!," broad, light 



grn., margined silver 



(tyn. Aiioectochilus 



pictus, 6", Ivs. 3" long,

 nobilis, Ivs. ovate, dark 

 grn., veined silver; 

 close to pictus (ayii. A. 

 nobilis).
