Dendrobinm crumenatum Sw. W. .sp. pl. n. 20. Ilort. Trans. VII. 70, 

 Dr. Blunie found it in Java , near Batavia and on ihe cost of ihe litllc island of Nusa 

 Kambanga ; and llie iate Sir Siamford Rafiles met wilh it in Sumatra. Rumphius gives 

 no locality for its referring from the body of his work to a description in the appendix ; 

 wbere however nothing is to be found exccpt a reference back to the body of the work ; ii 

 is doubtlcss however an inhabitant of Amboyne. The sj»ecimcn now flgured was scnt 

 by Mr. Nighlingale from Ceylon to his Gracc the dukc of Nortliumhcrland , in whose 

 coll. at Syon it flowered Aug. 37. — According Btume it varies wiih white and pink 

 flowers , wilh lcaves more or less oblong and coriaceous. It is one of ihe easiesl 

 of the gcnus to manage. Why it is called crumenalum (literaily purse- shapcd) I am 

 unable to state. Rumphius wiih whom the name criginated, givcs no explanation ; 

 but in one placc he calls it A. crumenatum , and in anolher Augrecum angustis cru- 

 mcnis. — Pcrigoniura album , labelli cristulis flavis.
