\aT. gultulata Rcbb. fil. in v. Schl. B. Z. 1852. 763: major. epichilii disco verrucu- 

 loso. Ich verdanke diese Pflanze der freundlichen Miitheilung des Herrn Josst im 

 graflich Thun'schen Garten zu Tetschen. Derselbe hat sie in seiner ,,Beschrei- 

 bung und Cultur der Orchideen" p. 334. unier Peristeria guttata var. viulacea be- 

 schrieben und bemerkt . er habe sie vou Hrn. Van Houtie bezogen. Sie gehort aber 

 zu P. cerina, weil die seillichen Lappen der Lippe sehr entwickelt sind ; auch ist die 

 Lippenspilze ausgerandet. Die Bluihenfarbe ist ochergelb mit vielen Purpurflecken, 

 Wiltellappen der Lippe stark purpurfarbig. 



4. PEBISTERIA GUTTATA Knowles Westc. Floral Cab. II. tb. 70. (1838): 



Scapo brevi, pendulo, muUifloro, racemo denso, secundo, labello di- 

 midio inferiori disco crasso concavo, lobis lateralibus vix conspicuis, 

 superiore ovalo, margine denticulato , apice inlegro abrupte incurvo, 

 intus tuberculis minulissimis obsito; columna aptera. 



Flowers erect. fleshy, ventricose, of a pale salmon colour, copiously marked wiih- 

 in and without wiih spots of a reddish purple or maron colour. and emitting a power- 

 ful, peculiar and agreeabie odour. Upper sepals ovate oblong, obtuse, lateral ones 

 enlarged and tuniid below. embracing and uniled with the base of the labellum. La- 

 bellum joinied in ihe middle. the upper portion or lobe erect, purplish at the apex, 

 lying against and parlly enibracing the column ; the inferior porlion concave , with 

 a fleshy border exiending from the joint to the base of the column. Column thick, 

 semiterete, spotied, much dilaied. 



Bot. Reg. XXVII. (1842.) Misc. 33: Allicd to pendula. from which il difl"ers in 

 ihe colour. the sliape and ihe smaller size of tbe ilowers , in the absence of wings 

 from ihe column, and in the scarcely developed lateral lobes of ihe labellum. It is 

 much more nearly allied to P. cerina of the Bot. Reg., wilh which it agrees in the 

 general shape of ihe flowers and the denticulated margin of ihe middle lobe of the 

 labellum. but dilTers from it in the colour and copious markings of ibe flower, in 

 the entire, nol emarginate point of the middle lobe and in the absence of distinct 

 iateral lobes. Still however the rcsemblance between them, except in colour, is so 

 great, ihat we quesiion, wheiher our plant niay not eventually be considered a spotted 

 variety of P. rcrina. Said to have been imported from Rio Janeiro — but this is 

 doubiful. Flowered with Mr. Barker.
