236 A SYNOPSIS OF THE SPECIES OF DIAPHORANTHEMA. 



The XDlaiit inistakeii by Klatt for Blnme's Lysimachia cuspidata 

 had not, I beheve, been noticed by any previous writer. It has 

 been very fairlj^ described and figured by him/'' though he is mis- 

 taken in supj)osing that it grows in Hongkong, or that Hongkong 

 itself is situated in Northern China. I therefore desire to dedicate 

 it to him, as the first describer, under the name of L. Klattiana. 

 So far as I know, it has only yet been found in Northern and 

 East-Central China, and its nearest relative is apparently L. Alfredi, 

 Hance. 



A SYNOPSIS OF THE SPECIES OF DIAPHORANTHEMA. 



By J. G. Baker, F.E.S. 



The large genus Tillandsia, as monographed by the younger 

 Schultes in the second part of the seventh volume of Pioemer and 

 Schultes's ' Systema Vegetabilium,' in 1830, has been much sub- 

 divided of late 3^ears. With the exce^^tion of Catopsis, Griseb. 

 {Fogonospermum, A. Brong.), which differs from Tillandsia materially 

 in the seeds, I prefer to regard the groups which have been sepa- 

 rated (Anoplophytiim , Diaphoranthema, Allardtia, Platystachys, 

 Phytarhiza, Wallisia, and Vriesea) as of not more than sectional 

 value. One of the best marked is Diaphoranthema, characterised 

 by Beer, m 1857 ('Die Familie der Bromeliaceen,' j). 153.) Beer's 

 synopsis of the species is not satisfactory, as out of eight which he 

 defines not more than three will hold good, and there are several 

 others which he does not mention at all. The head-quarters of 

 DiaphorantheDia is in the Argentine territory ; and it was studied 

 carefully a generation ago by the late Mr. Gillies, who gave names 

 to the sx^ecies he distinguished, and sent specimens to Sir W. J. 

 Hooker, but never published them. I propose, therefore, to devote 

 the present paper to a synopsis of the species which I have been 

 able to see in the London herbaria. 



Genus Tillandsia, Linn. 



Sub-genus Diaphoranthema, (Beer). — Leaves subterete, per- 

 sistently lepidote up to the toj) on both sides, not condensed into a 

 rosette, but spread over the short, produced simple or forked, 

 densely caespitose stems. Peduncle leafless or obscurely bracteate, 

 sometimes 0. Flowers erect, 1-3, crowded if more than one. 

 Petals violet, oblanceolate, shortly exserted from the calyx, not 

 scaled at the base of the claw. Genitalia shorter than the petals. 



1. T. hryoides, Griseb., in Lorentz PI. Argent. Exsic, No. 128. 

 T. coarctata. Gillies MSS. Stems 1-3 in. long, simx^le, or little or 

 copiously branched. Leaves very tightly X3acked on the stems, 

 50-100 to a fully-develoi)ed simj^le stem, ascending, adpressed to 

 the stem or rather sj^reading, subterete from a clasping lanceolate 

 base one-twelfth of an inch broad, narrowed gradually from the 

 top of the base to a tine j)oint, the whole blade :^-^-in. long,
