in licing 2-lo1ip(l, and, T tliink, may Ik; relinl upon as a sure and distinp;uishing 

 clianu-tcr of this gonus. Other gonura, iRTcaftor to be mentioned, have a eallus in or 

 near the same part of the spur, but in no case, as far as I liave seen, is it 2-lobed. 

 Species about 12. 



S. ERrXACKUM. 



A pretty fleshy-h^avcd spoeios, with stems only a few inches long. The leaves 

 are lanceolate and pointed. The tluwers are white, suffused with pink, and have 

 a fleshy incurved pointed lip of a deep rose colour. They hang down in elegant 

 racemes, varying from ;i to G inches. The rostellum, or beak of the column, is 

 prominent. The pods are covered with short rigid hairs, hence I gave the plant 

 the name of S. dasycarpon (shaggy-fruited), not " dtiKi/poffoii" (shaggy-bearded), as 

 erroneously stated in the Hotu/iical llugazine, but it pleased Professor Iteichenbach 

 to change the name to its present one, derived from Pliny's word for hedgehog, 

 a name of which I admit the e(iual titness with my own, though not a greater. 

 The flower-stem or rachis, and the exterior parts of the flower, are similarly clothed 

 with hairs. 



S. LAXUII. 



Similar in general character to the last, so much so that one description might 

 almost answer for both. The leaves, however, are more fleshy still, being, indeed, 

 of a very remarkable thickness, about \ inch thick and linear, with an unequally 

 oblique termination. They are generally stippled on the under-side with greenish- 

 purple. The flowers, which much resemble those of S. erinaeeus, have the lip of 

 a deep ruby-red, and a very prominent column and beak, which, together with the 

 outspread sepals and petals, give them the appearance of tiny birds poised in mid 

 flight. The pollen-gland of these two, as of the other flat-leaved species, is very 

 small, and the stipes very long and slender. It seems to be rather rare, and when 

 found by me it has always been on the boughs of small trees overhanging mountain 

 streams," which I happened to be crossing. It is nicely figured in " Saunders 

 refugium Eotanicum," tab. 109. 



S. TERETIFOLICM. 



This is a long slender pendulous plant, sometimes as nuicli as 4 feet long. 

 Leaves few, distant, all inclining to one side, terete, about the thickness of a crow- 

 quill, and 6 to 8 inches long. Flowers small — i- inch across— distant, numerous, 

 on a pendent raceme 8 or 9 inches long. Sepals and petals reddish-brown. Lip and 

 interior of flower lilac, spur slightly 2-lobed. 



8. WlLLIAllSO.Vl. 



Another terete-leaved species, but of erect growth, with shorter and stouter stem 

 and leaves, about the thickness of a goose-quill. The racemes, however, are slenderer, 

 simple or branched, and the flowers rather more numerous and smaller. Sepals and 

 petals pale salmon colour, lip lilac with deep ruby- red side-lobes. 



S. API'EXDICULATL-JI. 



This is Acrides append icuhitiim of 'Wallieh (Lindl. Gen. and Sp. p. 212). _ It is 

 also a species with terete leaves, stem erect, simple or branched, leaves about 4 inches 

 long, llaceme curved and drooping, 15 or 16 inches long, flowers on the last third 

 only, J inch across. Sepals and petals spreading and refle.xed, nearly equal, linear- 

 oblong. Lip 3-lobed with a pointed middle lobe and a conical spur. Colour, red- 

 brown stripes on a yellowish ground, lip yellow and purple, also striped behind on 

 the spur. 



This plant received its name in consequence of a peculiar appendage, "callo 

 magno tabulari a dorso calcaris projiciente," Lindley, inside the lip. It was the 

 discovery of this plant in 18o(i, at "The Tliree Pagodas," and the observation of this 

 singular" appendage, together with the fact that notice of it was taken by Lindley 

 (and so I was enalded unmistakably to id.'niify the species), that led me to pay special 

 attention to similar ai)i)endages, and to note their presence or absence, and accurately 

 to draw their varving forms.
