• Offsets usually employed. Difficult to handle. 



••• S*>me species form plantlets on old flower stems when pegged down on moss; otliera 

 form plantlets on the roots. 



Seeds. Hand pollination of cultivated orchids la necessary to secure seeds. Chooao 

 nearly related genera or S[>ecies where hybrids are desired, because distantly related ones 

 may not "take to each other." or the offspring may resemble the eeed-bearing parent. 

 Select for the seed-bearing parent a plant of vigorous health, free growth and flowering 

 habit, because the offspring usually •fake after the mother" in form, but after the 

 "father" in flower color. To pollinate, place one or more ripe pollen oiasses nn the right 

 ftignia of the female flower. Seeds require snnietiines three to six months, but oftener a 

 year, to rii>en. Sow seed as soon as ripe by dusting on surface I'f pnts or baskets in 

 which healthy plants of the same genus are grown. Keep moist with rery flne rose till 

 .seLKilings are started. Spring-sown seed usually sprouts quickest. Some 8i>ecles require a 

 yeiir or more to germinate. When seedlings have two or three leaves, plant In flats, or 

 singly in small pots, in compost suited to the parent, hut finer. Should compost become 

 sour, transfer seedlings to other soil. 



ADivisinn. Choose none but sturdy plants. Carefully remove soil. Cut plant with 

 keen knife so each piece will have at least one "lead." In eiime cases the pro- 

 cnmbt'iit rhizomes produce only one growth from the )iRcudo bulb. With these cut part 

 way tlirongb the rhizomes two or three pseudo bulbs behind the leaf, in late winter or 

 early spring. Count on one new bud fmm the base of the bulb next the division. Do 

 not separate till the lead la well eetablialied; then sever and pot. 



B Cuttings- Choose long-jointed species. In midwinter, just before plants start growth, 

 cut old psendo bulbs according to joints, l^ay pieces on moist moss in warm propa- 

 gating frame. \Mien yomig offshoots have started well, pot whole piece and plantlet. 

 Wbcrc the rhizomes form roots before cutting, leave surh roots on the lower parts of the 

 stems (at least a foot long), discarding the upper part. These stems produce new 

 growths, which may be rooted later.
