RhynchofityUs.] OXLVIII. ORCHIDE^:. (J. D. Hooker.) 33 



petals elliptic, obtuse ; epichile of lip very variable in size, usually cuneiform, entire or 

 eraargiuate at the tip, disk flat or obscurely channelled. Capsule 1-1| in., clavate. 

 Lindley errs in describing the fruit of R. Garwalica as different from .5. retusa, also in 

 describing the blade of the lip of Sacc. guttatum as lanceolate, which misled Wight, 

 who founded his S. Rheedii on the difference. 



SPECIES UNKNOWN TO ME. 



SACCOLABITJM BEEKELEYI, Reichb. f. in- Gard Chron. 1883, i. 814 ; from the 

 author's remarks (there is no description) this appears to be near R. retusa, but the 

 lip is acute ; the flowers are white with] amethyst spots. Its habitat is unknown, 

 but probably Indian. 



SACCOLABITTM LITTOEALE, Reiclib. f. I.e. 1881, ii. 198, has very long leaves, a 

 short raceme, and the epichile cucullate, keeled and turned obliquely on one side. 



56. SARCOCHXXiUS, Br. 



Epiphytes, stem short or long, pseudobulbs 0. Leaves distichous, or at 

 flowering time. Flowers racemose or spicate. Sepals spreading ; lateral 

 adnate by a narrow base to the base of the column, or by a broad base to 

 its foot, and sometimes to the lip also. Petals usually narrower. Lip 

 sessile or clawed, very varied in form, side lobes small or large fleshy or 

 petaloid, midlobe sometimes reduced to a pubescent callus, disk very 

 various with often a callus or spur within. Column short or long, foot more 

 or less produced ; anther 2-celled ; pollinia 2, sulcate, or 4 in pairs, strap 

 short broad. Capsule usually long, strict, slender. Species about 40 known, 

 tropical Asiatic, Australian and Pacific. 



A polymorphous genus, no doubt to be dismembered when better known. The 

 following attempt to group the Indian species possibly indicates the lines upon which 

 some of the genera may be established. 



A. Flowers loosely inserted all round the rachis of a more or less elongate raoeme 

 or spike. 



* Lateral sepals inserted by a narrow base to the base of the column, or base of 

 the column and sides of the lip. Foot of column or very short. 



Sect. I. Lip shortly clawed. Column short; rostellum minute. PTEBOCEEAS, 

 Hasselt. (Sp. 1-4.) 



Sect. II. Lip sessile or subsessile. Column long; rostellum very long, slender. 

 STEEEOCHILUS, Lindl. (Sp. 5.) 



Sect. III. Lip long-clawed. Column short ; rostellum very short. (Sp. 6-7.) 



Sect. IV. Stem elongate, scandent. Lip sessile. Column short ; rostellum very 

 long ; strap of globose pollinia very slender, gland minute. MICEOPEEA, Lindl. 

 (Sp. 8-11.) 



** Lateral sepals inserted by a very broad base to the elongate foot of the 

 column. 



Sect. V. Leafless when flowering. Stem 0. Side lobes of lip large, erect, mid- 

 lobe a tomentose pulvinus. CHILOSCHISTA, Lindl. (Sp. 12-15.) 



Sect. VI. Leafing and flowering together. Lip various. (Sp. 16-19.) 



B. Flowers in very short spikes at the apex of a slender scape, bracts persistent, 

 imbricate. 



Sect. VII. FOENICARIA. (Sp. 20-26.) 



C. Flowers distichous on a compressed rachis, which is pectinate from the 

 uniform persistent laterally compressed fleshy bracts. 



Sect. VIII. Peduncles stout, solitary. Lip stipitate, articulate with the foot of 

 the column. CTJCULLA. (Sp. 27-33.) 



Sect. IX. Peduncles filiform, fascicled. Lip sessile. RIDLEYA. (Sp. 34.)
